The Bray Series 6P positioner 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 Series 6P 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. Specify Bray Series 6P whenever valve positioning and sensitivity is critical.
For modulating control of valve positions, the Series 6P automatically positions the valve to precise angles between 0° and 90° in response to a pneumatic input signal. The standard positioner is Double Acting but can be easily converted to Single Acting/Spring Return. The 6P also has Split Range capabilities and an easy to adjust Span and Zero.
Mounting & Materials
The Series 6P can be installed directly on any quarter-turn valve actuator conforming to the NAMUR standard.
Contact your local Bray Distributor for information about mounting the 6P on non-NAMUR actuators.
The Series 6P housing is constructed from durable die-cast aluminum that is first anodized for internal corrosion resistance, then powder coated for external resistance to harsh environments.
Options/AccessoriesSPECIAL CAMS: Special cams for non-standard ranges may be modified by the factory or customer.AIR FILTER: A coalescing air filter is recommended for all positioners to eliminate dust, moisture, and oil particles from contaminating the unit.
Two-Stage Pilot RelayProvides fast, sensitive response characteristics for precise control of critical control valves and dampers.
Corrosion Resistant MaterialsAll exposed parts are either stainless steel or powder coated anodized aluminum to permit use in corrosive environments.
High Visibility Dome Position IndicatorProvides high-contrast, full-angle viewing of valve position.
Field UpgradableThe Series 6P is field-upgradable to a number of options including limit switches or a 4-20 mA position transmitter.
Vibration ResistantHigh natural frequency and pneumatic dampening make the Series 6P resistant to vibration.
Gauge Manifold3 gauges are provided for Signal, OUT 1, and OUT 2 ports.
