Dome-loaded pressure regulators withstand system pressure, withdrawal fluctuations

Witt-Gasetechnik has announced that it has improved the pressure consistency of its dome-loaded gas pressure regulators. A design modification to the newly integrated control pressure regulator ensures an almost complete compensation of supply pressure and outlet fluctuations, helping to keep gas supply constant at all times, the company states.

The control pressure regulator can be used to increase or reduce the gas pressure at any time, as soon as another working pressure is required. The control module is fully integrated into the housing to make the system more compact and maintenance-friendly. New materials for seals, diaphragm, and threaded joints have increased the temperature range to -22 to 122 degrees F.

The new sets are available with dome-loaded pressure regulators of types 737, 747, 757, 767, and 772. All casings are made of brass, but they also are available in stainless steel (with the exception of the 767).
