Stainless steel valve with bellows for harsh process conditions Suitable for 1 bar differential pressure Very easy maintenance thanks to simple wedge design Body material stainless steel Manual actuator with position indicator: 091 . . -. E08 Pneumatic actuator double acting without position indicator without solenoid with position indicator, without solenoid: 091 . . -. E24 with position indicator, with solenoid: 091 . . -. E44

Sealing materials Feedth rough 1 valve gate 3 gate seal V valve seat side 2 sliding elements 4 bellows Very robust design with wedge sealing system No grease and no moving parts in the vacuum Technical data Continued next page Depending on the process conditions shorter service Maximum values: depending on operating conditions Leak rate: - Valve seat Pressure range Differential pressure on the gate Differential pressure at opening Bellows feedthrough Cycles until first service - Valve body - Manual and pneumatic actuator - Position indicator - Valve body - Valve gate - Small parts (contacting...

Solenoid for impulse actuation Solenoid separate, for external mounting Bake-out jacket (picture 1) Shaft feedthrough with PTFE bellows (instead of metal bellows feedthrough) Ports (diagram 2) for roughing (by-pass), venting or for gauges Ordering information for options: Ordering No. of valve-X (e. g. 09140-PE44-X, X = port ISO-KF25 in position B) Technical data
