Series 5A Limit Switch
The Bray Series 5A and 5B Valve Status Monitors (VSM) provide visual and electrical indication of position on any VDI/VDE 3845 compliant quarter-turn device. Our solutions enable end users to better monitor their process no matter the conditions.
Features:
Enclosure: The compact low-profile weatherproof VSM is UL certified Type 4, 4x and IP66/67. A die-cast aluminum cover and base coated with a polyester powder coat for exceptional corrosion, wear, impact and ultraviolet resistance.
High Visibility Position Indicator: Visual Open and Closed indication is provided with an impact resistant dome style indicator. Inverting the Open and Closed visual output is easily done by removing the dome and rotating it 90 degrees. There is no need to remove the cover and expose internal wiring of the limit switch to change position indication.
Stub Shaft Secondary Seal: Ensures indicator area is separate from the VSM’s internals. Provides a secondary seal to prevent water ingress should the dome or dome seal become compromised due to adverse site conditions.
Captive Cover Bolts: The cover is attached to the base by captive stainless steel bolts placed outside the sealing area.
Protective Washers: Clear, nonmetallic, corrosion resistant washers are used to ensure coating integrity when cover bolts are tightened.
O-Ring Seal for Watertight Enclosure: The O-ring seal between the cover and base provides a weatherproof seal preventing internal corrosion.
Sensor Cams: Splined cam design allows for easy and accurate setting of switch activation without the use of tools.
Limit Switches: Multiple limit switch options and configurations to meet connectivity requirements.
Terminals: Clearly marked terminal blocks are angled towards the user to ensure easy access.
Conduit Entries: Two conduit entries available in either imperial or metric threads.
Grounding: Green color-coded, easy-access grounding bolt.
Series 52 Valve Status Monitor
The Series 52 offers the bounce-free electronic valve signaling required for all PLC, computer and solid state circuitry vital to process control and information networks. Costly external junction boxes are eliminated and field wiring costs are greatly reduced.Bray’s approach delivers the most compact, reliable and economical valve position monitoring system available.
Specifications:
• Models: DC NPN, DC PHP, AC, I.S., DeviceNet, PROFIBUS, ASi
• Electrical Connections: Inductive: M12(4 pin), 7/8"(5 pin)
• BUS Network: ASi Flat Cable, DeviceNET, ASi M12
• Housing: Valox
Moisture, Chemical and Corrosion Protection
The two proximity sensors are completely encapsulated with epoxy resin in a rigid polymer enclosure that is impervious to moisture and most chemical and corrosive agents. Once the multi-pin connection is made, the cable link to plant wiring is completely sealed eliminating the possibility of failure due to moisture. These protections make the Series 52 the best choice for hostile environments.
Electrical Connection
A multi-pin electrical connector is designed for full compatibility with today’s industrial wiring requirements.
Polymer Enclosure
Bray’s design of two sensors in one rugged enclosure greatly reduces space requirements and expensive housings needed for previous dual switch applications. The epoxy resin encapsulation protects the sensors against vibration or shock.
Local Position Indication
A Valve Position Pointer, made of highly visible yellow ABS material, shows valve position locally throughout the full range of travel.
• LED Indicators give positive verification that the sensors are electrically functioning and show the target position has been reached.
• High Visibility Valve Position Display: (optional) Prominently labeled and color coded – yellow for open, black for closed – the display indicates valve position throughout the full range of travel.

Precision digital control with proven reliability Bray’s Series 6A positioners were designed with ease of installation, simple calibration, efficiency and economy in mind. Units for rotary single acting and double acting actuators are offered as standard. Intrinsically safe versions are also available.
Bray’s BUS positioners offer all Series 6A features plus increased network communication and remote access to positioner parameters and diagnostics.
ON-LINE ADAPTIVE CONTROL: During operation, the unit continually optimizes control behaviors and travel times in response to changes in line media pressure.
DIAGNOSTICS: Bray’s Series 6A positioners feature corrective and preventative maintenance self-diagnostic checks. All diagnostics run constantly, may be continually monitored, and recorded.
AIR SUPPLY MONITOR: An additional feature of the Series 6A is an internal monitor that transmits a fault signal alarm if the air supply fails. The alarm is shown locally on the LCD and may be sent to the remote control panel.
LOCAL POSITION ADJUSTMENT: Valve position can be manually adjusted locally by removing the housing cover, then using the push buttons to override the remote command signal.
FLOW RESTRICTORS: Precise control of even the smallest pneumatic actuators through internal Flow Restrictors.
POSITION INDICATOR: In addition to the LCD display, valve position is clearly shown over a distance by a yellow indicator.
LOCKING DEVICE: For high vibration applications, the Series 6A features, as standard, a friction clutch locking device.
Auto Calibration
Calibration is easily performed by entering only three parameters into keypad push buttons. The less than 5 minute calibration process automatically determines the position of the travel limit stops, then measures and records the parameters for both the open and close positions.
Explosion Proof
Designed for hazardous and severe applications, Series 6A explosion proof positioners offer all the features of the waterproof units in a flame-proof enclosure.
The automatic calibration keypad push buttons in the explosion proof units are externally mounted and easily accessible behind a flap. The units can be controlled locally, even during operation, without removing the housing cover. The LCD display is viewed from behind a sodium glass explosion proof window.
Waterproof/Explosion Proof enclosures meet NEMA 4,4x,7 & 9 specifications. These enclosures are constructed of die cast aluminum with an epoxy coating for chemical and corrosion protection. A waterproof Stainless Steel enclosure is available upon request.

Series 6P Pneumatic Positioner
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.
Applications
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/Accessories
SPECIAL 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 Relay
Provides fast, sensitive response characteristics for precise control of critical control valves and dampers.
Corrosion Resistant Materials
All exposed parts are either stainless steel or powder coated anodized aluminum to permit use in corrosive environments.
High Visibility Dome Position Indicator
Provides high-contrast, full-angle viewing of valve position.
Field Upgradable
The Series 6P is field-upgradable to a number of options including limit switches or a 4-20 mA position transmitter.
