Description
Actuator manual, hexagon head SW 17 Feedthrough bellows Technical data Leak rate - To the outside ≤ 1 . 10-10 mbar ls-1 - Seat ≤ 1 . 10-10 mbar ls-1 Molecular flow conductance 50 ls-1 Pressure range UHV to 5 bar (abs) Test pressure 1 bar Differential pressure on the gate - in closing and opening direction ≤ 5 bar Max. differential pressure at opening - in closing and opening direction 1 bar (> 1 bar at reduced cycle lifetime) Cycles until first service 10'000 Bake-out temperature (incl. actuator) - open ≤ 450°C - closed ≤ 350°C Heating and cooling rate ≤ 60°C h-1 Material - Body, Mechanism (in contact with media) 1.4435/1.4404, AISI 316 L; 1.4435, AISI 316 L, ESU - Bellows 1.4404, AISI 316 L Seal - Bonnet, Plate metal Mounting position any Radiation resistance - Valve / Actuator 108 Gy (1010 rad) Turns per stroke 8 Weight 2.3 kg / 5.1 lbs Attachments Dimensional drawing No. 233056 Comments The all-metal angle valves Series 57.1 are sealed with the patented VATRING sealing system (hard to hard). VAT Series 57.1 all-metal angle valves, with manual actuator, use a hexagon head for closing. The valve has not to be closed with a specific closing torque, it is closed to a mechanical stop. During the specified cycle life of 10'000 cycles no service is necessary.
