FAQ
- A pressure regulator is a self-operated valve that maintains a target pressure downstream (or upstream) of itself. A spring-loaded diaphragm or piston senses the pressure and modulates a valve port to hold it at setpoint. No external power, no controller, no signal wiring. Used everywhere from instrument air drops to gas distribution to industrial steam systems.
- Pressure-reducing regulators hold a constant downstream pressure regardless of upstream variation. The standard gas-and-air regulator: high pressure in, controlled lower pressure out. Back-pressure regulators hold a constant upstream pressure by opening to vent or relieve when upstream gets too high. Used for surge protection, pump relief, and maintaining tank or header pressure. Same mechanism, different sensing port location.
- Start with three numbers: maximum required flow at the outlet, inlet pressure range, and outlet pressure setpoint. Use the manufacturer's flow curves to find a regulator that delivers your flow at your pressure drop without drooping (where outlet pressure falls as flow increases) more than your process can tolerate. Oversize and you'll get poor low-flow control; undersize and you'll starve the downstream. Safety note: always install a properly sized relief valve downstream of any pressure regulator on critical service - a regulator can fail open, and the downstream piping and equipment must be protected per ASME BPVC. For oxygen and other compressed gas service, additional CGA guidelines apply.
