UNOX Three-Piece Flanged Double Acting Pneumatic Actuator Stainless Steel Ball Valve

What is a Pneumatic Actuator Stainless Steel Flanged Ball Valve?

A flanged ball valve is a type of valve used in piping or machinery systems to control the flow of water, gas, or other fluids. It is designed with a ball-shaped flow control element that allows direct flow when open. Due to this structure, flanged ball valves are commonly used in pressurized systems and are suitable for high flow and high pressure applications.

Flanged ball valves are mounted onto a flange connection, which creates a secure interface between the valve and the pipeline. This ensures a strong mechanical connection and a leak-proof sealing performance.

Pneumatic actuator stainless steel flanged ball valves are operated using compressed air. Depending on system requirements, they can be used in industrial automation applications where reliable and fast flow control is needed.

Pneumatic Actuator Torque Values

Depending on the connection size, pneumatic actuators with torque values ranging from 9 Nm to 400 Nm are used. Optional accessories such as switch boxes and directional control valves can also be integrated.

• UDA 040 = 9 Nm
• UDA 052 = 25 Nm
• UDA 063 = 50 Nm
