Pressure Regulator utilizes closed-loop technology.
Housed in IP65 enclosure, Series QPV provides high resolution pressure control. Output pressure is proportional to electrical command signal input and is unaffected by changes in supply pressure. Pressure is controlled by 2 solenoid valves; inlet valve operates proportionally to flow required to maintain system pressure. Variable orifice effect allows precise control of pressure at low flow...

Electronic Pressure Regulator uses O-rings for seat.
Model QB3 incorporates electronic pressure sensor that detects downstream pressure at work port for accurate regulation. Replaceable O-rings for intake and exhaust valve are set into groove that captures O-ring, but leaves room to move slightly and seal correctly for positive shut-off. Regulator accepts 0-10 V or 4-20 mA command signal and provides analog output that corresponds to actual...

Control Valve combines valve, actuator, and positioner.
FCV 1 in. control valve incorporates LVDT for detecting position; actuator; and electronics and pneumatics positioner to open and shut valve. Available in normally open or normally closed versions, product operates with command signal of 0-10 V or 4-20 mA. Valve position and Cv changes linearly over 0-19 Cv range.

Flow Transducer provides real-time measurement.
Contained in NEMA 4 housing, Series F measures gas flows as low as 2 scfh with real-time output of 0-10 V or 4-20 mA. Pressure changes that occur when gas is passed through venturi orifice are measured and used to determine flow of gas. Output is linear over flow range.

Electronic Pressure Regulator delivers high relief flow.
Offering reverse flow rates in excess of 25 scfm @ 100 psi, the QB3 electronic pressure regulator makes backpressure and high relief applications possible without use of a quick exhaust valve. It uses solid-state pressure sensor to monitor pressure at work port and electronically adjusts the integral regulator to desired pressure by filling or exhausting air from system. Product can be calibrated...
