Large gate valves Low shock, damped opening and closing Differential pressure possible on either side Proven design, used in large research and industrial systems as well as in space simulation Body material stainless steel Series 190 HV gate valve Pneumatic actuator double acting with position indicator with solenoid Series 192 UHV gate valve Ordering numbers (specify control voltage) Series 190 HV gate valve ISO-F Series 192 UHV gate valve ISO-F without position indicator, without solenoid: 19 . . . - . E14 with position indicator, without solenoid: 19 . . . - . E24 Other sizes Projects for special versions Our product groups are experienced in developing special requirements concerning material, stability, heaters, etc. On customer request, we can perform special test programs, bakeout and provision of customer specific hand-over quality documentation. Acceptance tests are conducted for large special projects, and are prepared by our engineers. Large VAT gate valves have proved their reliability in various large systems all over the world. Reference list available on request.
