Unox Double-Acting Pneumatic Actuator U-PVC Ball Valve

What is a Pneumatic Actuated U-PVC Ball Valve?

A U-PVC (unplasticized polyvinyl chloride) ball valve is a type of valve used to control the flow of liquids, gases, or other materials through pipes or other flow systems. It consists of a spherical component fixed inside a body and enclosed by a casing. The ball has a hole through its center, and when the valve is open, this hole aligns with the flow path, allowing material to pass through. When the valve is closed, the ball is rotated so that the hole is perpendicular to the flow, stopping the passage of material.

Where Are Pneumatic Actuated U-PVC Ball Valves Used?

U-PVC ball valves are commonly used in plumbing and water treatment systems, as well as in various industrial and commercial applications. They are known for their durability, corrosion resistance, and ease of maintenance. Since they require only a quarter turn to open or close, they are relatively easy to operate.

In general, U-PVC ball valves provide a reliable and cost-effective solution for controlling material flow in various applications.

Ball Valve Construction:

• Aluminum extrusion body, corrosion-resistant inside and out, with a precision-processed cylinder surface for long life and low friction coefficient.

• Symmetric and easy mounting position; compact pistons made from special aluminum alloy enable fast operation and simple reversal of piston direction by repositioning.

• Optional mounting at 45°–90° angles with a symmetric, corrosion-resistant, high-quality steel pinion compatible with the piston stroke at any mounting angle.

• Fast opening and closing capability, low friction coefficient, and industrial-grade hard plastic bearing elements that minimize wear on friction surfaces.

• Pistons and pinions equipped with precision-machined module gears produced by special processing techniques, ensuring silent, compatible, and maximum efficiency operation.

• Long-lasting corrosion-resistant stainless steel fastening elements.
