BRAY VALVE CONTROLS 93-2105-11300-532 DOUBLE ACTING ACTUATOR S.N 148891

The Bray Controls 93-2105-11300-532 is a Double-Acting, Pneumatic Rack-and-Pinion Actuator. It is a robust, quarter-turn (90-degree rotation) device designed to automate industrial ball, butterfly, and plug valves.

Core Function:
It converts compressed air energy into rotary torque to open and close a valve. “Double-Acting” means compressed air is supplied to both sides of the internal pistons. Air pressure drives the piston in one direction to open the valve, and pressure on the opposite side drives it closed.

Key Specifications & Features :

1. Actuator Type: 93 Series – This is Bray’s flagship line of high-performance, modular rack-and-pinion actuators, known for durability and easy field servicing.

2. Size: 21 – The “21” indicates the actuator size, which corresponds to its output torque range. A size 21 is a mid- to large-frame actuator, typically generating significant torque (exact ft-lbs/Nm depends on supplied air pressure).

3. Action: 05 – This code specifies a Double-Acting (DA) mechanism.

4. Accessory Package / Options (11300): This is a critical part of the code that defines the built-in controls and accessories. “11300” typically signifies a comprehensive package that includes:

   • Solenoid Valve(s): For electrical on/off control (likely a 5-port, 2-position solenoid).

   • Limit Switches (Mechanical or Proximity): To send electrical signals indicating the fully open and fully closed valve positions to a control system.

   • Visual Position Indicator: A mechanical flag or pointer showing “OPEN” / “SHUT.”

   • Manual Override: A hand lever or crank to operate the valve if air pressure is lost.

   • Air Connections: Standard NPT ports.

   • Electrical Conduit Entry: One or more entries for wiring.

5. Mounting & Interface (532): This designates the specific mounting configuration and valve interface.

   • It defines the drive shaft size, shape (e.g., ISO 5211 standard), and bolt pattern.

   • The “532” configuration is engineered to directly mate with a specific range of Bray (and often other manufacturers’) valves using an ISO 5211 F10 or F12 flange, a common industry standard. It includes the correct coupling and bolts.

Summary of Characteristics:

• Model: 93-2105-11300-532

• Serial Number: 148891 (This unique identifier is used for tracing manufacturing records, warranty, and exact configuration details with Bray.)

• Operation: Double-Acting Pneumatic (requires compressed air supply to both open and close).

• Fail-Safe Mode: None. Upon loss of air pressure, the valve will stay in its last position (unless a secondary spring-return module is added). This is a “fail-in-last” design.

• Control: On/Off (from the integrated solenoid). Not typically used for precise modulating control.

• Typical Supply Air Pressure: 40-120 PSI (3-8 bar) is standard.

• Applications: Used in demanding industries such as:

  • Oil & Gas Production and Refining

  • Chemical & Petrochemical Processing

  • Power Generation

  • Water & Wastewater Treatment

  • Marine & Offshore Systems
