DOME PRESSURE REGULATOR SET 737 LE/S Complete solution, own-medium controlled  High performance dome-loaded pressure regulator set. For high and varying flows requiring maximum pressure stability. Features ●● Balanced Seat Design (BSD) Further enabling control precision, high reliability and low maintenance For this we offer our Maintenance Set with original spare parts. ●● A complete solution, ready to use With integrated pilot pressure regulator, and stainless steel pressure gauges, completely assembled and tested Enabling autonomous operation (no separate gas supply required) 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. 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 Depending on application, moving wetted parts may need replacement every 1-3 years.
