BODY①

The body is in cast steel. The basic dimension,i.e.wall thickness,face to face and flange comply with the relevant API and ANSIstandards. The body-to-bonnet flange is circular and the sealingsurface for connection to the bonnet are recessed in the 150lb and300lb class or may be ring joint in the high classes. Bosses areprovided for drain taps or by-pass piping.

BONNET②

The bonnet is in cast steel. It is machined to accept the yokesleeve and incorporates a stuffing box dimension in accordancewith the API standard.

DISC③

The disc is part of the trim. It is in cast stainless steel for diametersup to 8” and in cast steel for larger valves. It is normally supplied ofthe flat, tapered or plug type or, on request, of the parabolicregulating type, always free to rotate on the stem. Special attentionis given to the seating face which is ground and lapped, for aperfectly tight seal.

STEM⑤

The stem is part of the trim. A ground backseat is provided toensure a perfectly tight seal to the stuffing box when the valve isfully open. The stem is attached to the disc by means of athreaded ring which allows the disc to rotate. The stem is ground tominimize friction and prevent damage to gland packing.

YOKE SLEEVE⑦

The yoke sleeve is made from cast austenitic ductile iron havinghigh resistance to wear and a high melting point. It is screwed intothe bonnet and properly sized to withstand the stresses whichdevelop when opening and closing the valve.

BONNET BUSHING⑥

The bonnet bushing or backseat is part of the trim. Specialattention is give to its machining and heat treatment to insure aproper seat for gland repacking under pressure. Special attentionis given to the seating face which is ground and lapped, for aperfectly tight seal.

BODY①

The body is in cast stainless steel and is carefully designed in allits details. The basic dimension,i.e.wall thickness, face to face andflanges comply with the relevant API and ANSI standards. Thesealing surfaces for connection to the bonnet are flat finish in the150lb Class, recessed in the 300lb Class or may be ring joint in the600lb Class and above. Bosses may be provided for drain taps orby-pass piping.

BONNET②

The bonnet is in stainless steel. It is machined to accept the yokesleeve and incorporates a stuffing box dimension in accordancewith the API standard.

WEDGE③

The wedge is part of the trim. It is normally supplied as flexible. It isconnected to the stem by means of a T-joint. The guides on eachside of the wedge are casted for proper alignment with the bodyguides. Special attention is given to the seating surface which areground and lapped to insure a perfectly tight seal.

STEM④

The stem is part of the trim. A stem is provided with a T-head. Aground backseat is provided to ensure perfectly tight seal to thestuffing box when the valve is fully open. The stem is ground tominimize friction and prevent damage to gland packing. Thethreading is trapezoidal ACME type. Dimensions comply with theapplicable standard.

YOKE SLEEVE⑤

The yoke sleeve is made from bronze, stainless steel or ductileiron having high resistance to wear and a high melting point. It isdesigned to permit removal from the bonnet or the yoke while thevalve is in service. Gate valves 6” 600lb Class and above are fittedwith a ball thrust bearing.

HANDWHEEL⑭

The steel or nodular iron handwheels are well shaped and largeenough to give ease of movement when operating the valve, evenunder maximum differential pressure.

BONNET BOLTING⑨,⑩

Bonnet studs and nuts are manufactured from alloy or stainlesssteel to the relevant ASTM standard.

The body-to-bonnet flange is circular and thesealing surface for connection to the bonnet are recessed in the150lb and 300lb class or may be ring joint in the higher classes.The body may be threaded for a renewable seats. Bosses may beprovided for drain taps or by-pass piping.

BONNET②

The bonnet is in stainless steel. It is machined to accept the yokesleeve and incorporates a stuffing box dimension in accordancewith the BS standard.

DISC③

The disc is part of the trim. It is normally supplied of the flat,tapered or plug type or, on request, of the parabolic regulatingtype, always free to rotate on the stem. Special attention is given tothe seating face which is ground and lapped for a perfectly tightseal.

STEM④

The stem is part of the trim. A ground backseat is provided toensure perfectly tight seal to the stuffing box when the valve is fullyopen. The stem is attached to the disc by means of a threaded ringwhich allows the disc to rotate. The stem is ground to minimizefriction and prevent damage to gland packing.

YOKE SLEEVE⑤

The yoke sleeve is made from bronze, stainless steel or ductileiron having high resistance to wear and a high melting point. It isscrewed into the bonnet and properly sized to withstand thestresses which develop when opening and closing the valve.

BODY①

The body of the high pressure gate valve is designed as an onepiece casting, with smooth inside contour providing maximum flowefficiency. The body has an integral casting guiding system to guide thewedge full throught the valve stroke. The pressure seal type gate valve is designed with 4 holes in theneck at the region of the segmental retainer for a proper disassembly.The contacting surface the pressure seal gasket outside has astainless steel 18-8 inlay to assure soundness and corrosionresistance for carbon and alloy steel valves. The body is seal welding for body seatrings.

BONNET②

The bonnet is designed and manufactured in order to ensure aperfect seal, as well as to allow for easy dismounting and reassembly.A longer packing life is ensured by a condensation chamberinserted between the backseat and the packing.

FLEXIBLE WEDGE③

The flexible wedge is circumferentially symmetrical in order toensure a complete distribution of forces and to ensure thatpossible irrgularities of alignment can be compensated.The flexible wedge design is based upon the elasticity of thewedge material.The flexible wedge contacting surface with deposit stellite no.6hard facing is ensured by pressure tightness and freedom fromsticking. It is connected to the stem by means of a T-joint.Special attention is given to the seating surfaces which are groundand lapped to ensure a perfectly tight seal.

STEM④

The non-rotating rising stem has trapezoidal thread.The stem is ground to minimize friction and prevent damage togland packing. The stem is jointed to the wedge by means of a T-connection which is an integral part of the stem itself. Thestemhead has a tapered shoulder for backseating purposes.

BODY SEAT RINGS⑤

The seat rings are made of the same material as the body, andsurfaces have stellite no.6 hardfacing.Special attention is given to the seating surfaces which are groundand lapped to ensure a perfectly tight seal.

BACKSEATThe bonnet of the high pressure gate valve has an integralbackseat design with hardfacing and provides tight sealablity dueto contact between the backseat and the taperes shoulder stem.Backseating of the valve results in positive isolation of the stuffingbox from the pressure area in case of packing failure.A ground backseat is provided to ensure a perfectly tight seal tothe stuffing box when the valve is full open.

STEM④

The non-rotating or rotating rising stem has trapezoidal thread.The stem is ground to minimize friction and prevent damage togland packing. The stem is jointed to the disc by means of a locknut. The stemhead has a tapered shoulder for backseatingpurpose.

SEAT⑤

The seat is integral welded to the valve body and is provided with ahardfaced sealing to assure better wear and longer valve life. Special attention is given to the seating surfaces which are groundand lapped to ensure a perfectly tight seal.

BACKSEATThe bonnet of the high pressure globe valve has an integralbackseat design with hardfacing and provides tight sealablity dueto contact between the backseat and the tapered shoulder stem.Backseating of the valve results in positive isolation of the stuffingbox from the pressure area in case of packing failure.A ground backseat is provided to ensure a perfectly tight seal tothe stuffing box when the valve is full open.

BODY①

The body of the high pressure sw-ch valve is designed as an onepiece casting, with smooth inside contour providing maximum flowefficiency. The pressure seal type sw-ch valve is designed with 4 holes in theneck at the region of the segmental retainer for a properdisassembly.The contacting surface the pressure seal gasket outside has astainless steel 18-8 inlay to assure soundness and corrosionresistance for carbon and alloy steel valves. The body is seal welding for body seatring.

BONNET②

The bonnet is designed and manufactured in order to ensure aperfect seal, as well as to allow for easy dismounting andreassembly.

DISC③

The disc contacting surface with deposit stellite no.6 hard facing isensured by pressure tightness and freedom from sticking. It isconnected to the arm by means of a disc nut. Special attention is given to the seating face which are ground andlapped to ensure a perfectly tight seal.

HINGE PIN⑤

The hinge pin is part of trim. The hinge is retained in the body athread plug and sealed by metallic gasket.The hinge pin can be easily removed for maintenance of the valve.

SEAT RING④

The seat ring are made of the same material as the body, and thesurface have stellite no.6 hardfacing. The seat is welded into thevalve body preventing leakage between seat and body.Special attention is given to the seating surface which are groundlapped to ensure a perfectly tight seal.

THT pressure valves are designed for high pressure, and high temperature applicable service in nuclear power plants, chemical plants andthermal power plant.The pressure seal bonnet joint remains tight under all conditions. The initial seal is established by the inner row of studs. The higher theinternal pressure. The greater is the sealing force.

⦁ EASY DISMANTLINGby dropping bonnet assembly into body cavity and driving the 4-segmentalthrust rings by means of a push pin. A 1 。 body taper above the 18-8 inlayinsures easy sliding of the gasket even after years of service.

⦁ INNER ROW OF STUDSestablishes the initial seal of the Pressure Seal joint.

⦁ OUTER ROW OF STUDSsecures the yoke to the body.

⦁ SEGMENTAL RETAINERabsorbs all the thrust applied by internal pressure.

⦁ DRILLED KNOCK-OUT HOLESfor driving out thrust rings. using pins.

⦁ ADAPTER RINGprovides bearing surface and prevents deformation of the gasket.

⦁ SOFT STEEL SEALING GASKETof 100 Brinnel. silver-plated for soft corrosion-resistant coating. provides largecontact area for perfect sealing.

⦁ 18-8 INLAYassures soundness and corrosion resistance in the vital body sealing zone forcarbon and alloy steel valves.

All seating faces and important wear surface are hard-faced with Stellite 6. Thehard erosion and abrasion resistant cobalt-chrome alloy ensures long life of allworking parts. such as seats, backseats, wedges, and disc surfaces.
