Gases, drinking water, hot liquids and steam are the application

focuses of the type 6240 piston valve. The body, seals and design

were selected in accordance with the required certificates and

general requirements.

The piston solenoid valve 6240 combines the advantages of

a servo-controlled and a direct-acting valve. It is suitable for both

high pressures and large diameters. The fixed coupling between

the pilot valve and piston of the main seat ensures complete

opening even without differential pressure. The advanced piston

design and optimal fluidic geometry allow surprisingly good flow

rates even with small diameters.

The material and construction form the basis for a valves reliability and

safe operation. Especially fuel gases and steam place high requirements

on the materials used. The 2/2-way piston valve type 6240 features a large

selection of tested materials. This makes it possible to adapt the valve to

specific applications.

The following versions are available:
