Information

High performance dome-loaded pressure regulator set.
For high and varying flows requiring maximum pressure stability.

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 (no separate gas supply required)

Closed system
Self-relieving design, but 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.

Glycerine-filled manometer, unfilled version for oxygen

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.

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