Bray Commercial 70E121-113DA536/K Actuator

The Bray Commercial 70E121-113DA536/K Actuator is a heavy-duty 120V electric actuator designed for high-torque industrial valve automation. Delivering 1200 lb-in of torque, this Series 70 NEMA 4/4X enclosure unit is built to withstand rigorous HVACR and process environments. It features a die-cast aluminum alloy housing and is the direct replacement for the legacy 70-0121-113DA-536K model. This high-torque industrial actuator utilizes a permanent split capacitor motor with internal thermal overload protection and a standard manual override handwheel for emergency operation. For technicians looking for on-off or modulating control in automation or material handling, this unit provides precise mechanical travel stops and a visually clear position indicator. Its Bray Series 70 electrical actuator design ensures seamless integration into existing 120VAC control loops, maintaining reliable operation in manufacturing and commercial plant maintenance.

• High Output Performance: Provides 1200 lb-in torque to handle demanding butterfly and ball valve applications easily.
• Rugged Enclosure: Rated for NEMA 4, 4X, and IP65 to resist corrosion and moisture in harsh mechanical rooms.
• Manual Override: Features an integrated handwheel for safe manual positioning during power loss or system testing.
• Internal Safety: Built-in thermal overload protection prevents motor burnout during high-duty cycle operations.

Common Questions

What is the primary difference between the 70E121 and the older 70-0121 model?
The 70E121-113DA536/K is the current production standard, offering updated internal electronics and improved sealing, while maintaining the same physical mounting footprint and 120V actuator wiring specifications as the discontinued model.

Can this actuator be mounted in any orientation?
While these Bray butterfly valve actuators can be mounted in various positions, it is industry best practice to install them with the motor upright to prevent moisture accumulation and ensure long-term grease distribution in the gear train.

Does this unit support 24V control signals?
This specific model is a 120VAC actuator. If your control system requires 24V or a 4-20mA signal for modulation, verify the specific sub-model code (DA536/K) to ensure it matches your site-specific controller requirements.
