Control the pressure in your gas or liquid system with our compact Pressure Regulators or High Pressure Regulator Packages. Both can use the gas* from the system as the supply to actuate the valve. We can also build a custom regulator package for Hi-Low Regulation, Gap Control, Worker Monitor, Redundant Regulation, or any other need you have. *Gas used for actuation must be relatively clean and dry. Liquid pressure regulators require an outside supply of air or gas, except for our Spring Loaded Back Pressure Regulators.
