Bray VP700-G-T1 Electro-Pneumatic Positioner 4-20mA with Gauges

The Bray VP700-G-T1 Electro-Pneumatic Positioner is a general-purpose valve and damper positioner engineered to deliver precise pneumatic actuator control in HVACR and industrial process environments. Accepting a standard 4–20 mA input signal, this positioner converts the electrical control signal into a proportional pneumatic output that accurately drives rotary or linear actuators to the commanded position.

Designed for demanding applications, the VP700-G-T1 features a rugged, corrosion-resistant enclosure and a high-visibility flat 90-degree position indicator. Port gauges are constructed of brass and provide clear signal (G1/G2) pressure readings at a glance. The unit operates across a wide supply pressure range of 30–150 PSI and is rated for ambient temperatures from -40°F to 150°F, making it suitable for both indoor mechanical rooms and outdoor installations.

A linear characterizing CAM combined with a standard flow spool valve delivers a linearity of ±1.0% maximum, ensuring repeatable, tight deadband control required by automated valve systems. Air consumption is an efficient 0.25 SCFM at 80 PSIG, reducing compressor load in multi-positioner installations. Gain is rated at 250 for single-acting configurations and 500 for double-acting setups.
