Product Overview
Fast and sensitive response for precise and demanding control objectives
NAMUR-compatible positioner providing fast, sensitive response for quarter-turn valve control
For double-acting and spring-return actuators
The Bray Series 6P positioner delivers exceptional control for a range of quarter-turn valves. This design is fast and sensitive, using a 3-15 psi pneumatic control signal to meet the most demanding control objectives. Standard features include a highly visible dome position indicator and 3 gauges. The 6P series offers a variety of options, including position feedback limit switches and a 4-20 mA position feedback transmitter.
Features
The Bray Series 6P positioner is designed to control quarter-turn valves including butterfly and ball valves (standard or segmented). Its sensitive dual-poppet relay makes it ideal for precision damper control applications. When valve positioning and sensitivity are critical, the Bray Series 6P is the solution of choice. The 6P series automatically positions the valve at precise angles between 0° and 90° based on the pneumatic input signal for modulating valve position control. The standard positioner is double-acting but can be easily converted to single-acting/spring-return. The 6P also features split-range capability with easily adjustable span and zero.
Mounting and Materials
The 6P series mounts directly to any NAMUR-compatible quarter-turn valve actuator. Contact your local Bray distributor for information on installing the 6P series on non-NAMUR actuators. The 6P series housing is constructed of durable die-cast aluminum, first anodized for internal corrosion resistance, then powder-coated for enhanced external environmental protection.
Options/Accessories
Special cam: Factory or field convertible special cam for non-standard ranges
Air filter: A coalescing air filter is recommended for all positioners to eliminate dust, moisture, and oil particles, preventing unit contamination
