Information
High-performance dome-loaded pressure regulator-set.
For high and varying flows requiring maximum pressure stability.
A complete solution, applicable as a manifold pressure regulator per DIN EN ISO 7291.
Features
- Pilot Control Tube (PCT)
One of the features enabling highly accurate control of outlet pressure - Balanced Seat Design (BSD)
Further enabling control precision, high reliability and low maintenance - A complete solution, ready to use
With integrated pilot pressure regulator, and stainless steel pressure gauges, completely assembled and tested - Own-medium controlled
Enabling autonomous operation - Closed system
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.
Maintenance
- 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.
