Operation / Usage

Ideal for process gas supply where pressure accuracy is required even when inlet pressures and flow rates are varying. High flow rates and outlet pressure accuracy are achieved, even when the difference between inlet and outlet pressures is small. Own-medium controlled, with integrated pilot gas regulator, meaning no separate gas supply is required.


Annual testing of body leak tightness is recommended. Depending on application, moving wetted parts may need periodic replacement. Device-specific Maintenance-Kit available upon request.
