No gas is released to atmosphere
- Simple to install and operate
Removable spindle enables simple setting of the required outlet pressure. Can be positioned at any angle / orientation. For indoor and outdoor installation.
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.
