Butterfly Valve Actuator - 4" 5" & 6"

Butterfly Valve Actuator - 4" 5" & 6"

This is a Bray International Series 92 pneumatic actuator, model 92-0830, designed for the automation of quarter-turn butterfly and ball valves. Its rack and pinion mechanism converts compressed air into rotational motion to open or close a valve, making it a crucial component for automated flow control systems in concrete batch plants and other industrial settings. This actuator is needed to replace a failed unit or to upgrade a manual valve to automated service, ensuring reliable and remote operation. The unit is engineered with a compact, self-contained design featuring an anodized aluminum body and polyester-coated end caps for corrosion resistance.

Key Features

• Rack and pinion, opposed-piston design for linear torque output.
• Double-acting operation for pneumatic control in both open and closed directions.
• Anodized aluminum body and die-cast aluminum end caps with polyester coating for corrosion resistance.
• Adjustable travel stops for precise bidirectional movement adjustment (+/- 5 degrees).
• Permanently lubricated guides and bearings for smooth operation and minimal maintenance.
• Designed to mount directly to Bray valves per ISO 5211 standards, eliminating the need for external brackets.
• Suitable for both on/off and throttling applications.

Fits These Mixers

Vince Hagan, CMW, Con-E-Co, Erie Strayer, Stephens, Donaldson Torit. This actuator is part of the Bray Series 92 line, which is used across a range of valve sizes. The specific '0830' model is most directly referenced for use with 3" and 4" (DN65-DN100) butterfly valves. It is listed as a component for actuator assemblies on valves from 2" up to 12" depending on the specific valve series and torque requirements. Vince Hagan, a concrete batch plant OEM, uses Bray Series 92 actuators on their 4" butterfly valves. Actuator selection is ultimately determined by the torque requirement of the specific valve, not just the pipe size.
