Low pressure & high flow UHP cylinder valve with pneumatic actuator - D387
D387 low pressure pneumatic cylinder valve for UHP, corrosive, reactive and toxic gases is designed with the tied-diaphragm in order to keep the highest level of purity of the gas. Its 8mm orifice size allows a high CV value.
Key advantages
- Reduced dead space and gas wetted volumes allow easy purging
- No particle generating threads in the gas wetted part
- Prevents seizure - Gas does not come into contact with the valve operating mechanism
- Back-up welded diaphragms provide a permanent and durable gas tight seal
