Bray International Pneumatic-to-Pneumatic Positioner (Series 6P) provides outstanding control for a wide range of quarter-turn valves. This design provides fast, sensitive response characteristics to meet the most demanding control objectives using a 3-15 psi pneumatic control signal. A high visibility dome position indicator and 3 gauges are provided as standard. The Series 6P is available with many options including position feedback limit switches, and a 4-20 mA position feedback transmitter.
Bray pneumatic-to-pneumatic positioners are used to control quarter- turn control valves such as butterfly and ball valves (standard and segmented) and its sensitive two-stage relay makes it ideal for precise damper control applications. For modulating control of valve positions, the actuator automatically positions the valve to precise angles between 0° and 90° in response to a pneumatic input signal. The standard pneumatic positioner is double acting but can be easily converted to single acting/spring return. Series 6P also has split range capabilities and an easy to adjust span and zero.
