Pneumatic, electric or hydraulic actuators with ancillary equipment, such as solenoid valves, limit swit-ches, positioners etc. can be supplied.

Also availble:Valves with actuator and free shaft end to suit existing operating methods as described above.

Soft seat: Elasticity of the seat

and fl uid pressure assures

perfect “bubble tight” sealing.

Fire safe seat: After a fi re when

the PTFE-R seat has burned away,

the supplementary metal sealing

seat activates automatically and

prevent from excessive fl op.

Metal seat: This version offers

very high sealing capability with

an unusually low leakage rate.
