RF Valves Manual Pinch Valves are mechanically actuated flow control valves designed to regulate or isolate media by compressing a flexible elastomer sleeve.
These valves are widely used in applications involving abrasive slurries, corrosive fluids, and solids-laden media where traditional valve designs may experience excessive wear or clogging.
The manual actuation mechanism—typically a handwheel or lever—allows operators to directly control the opening and closing of the valve, providing reliable shutoff and throttling capability without the need for external power sources.
The core design of Manual Pinch Valves centers on the sleeve as the only wetted component, which helps minimize maintenance requirements and reduces the risk of contamination. When actuated, the valve compresses the sleeve to restrict or completely stop flow, then returns to its original shape when released. This simple yet effective operation supports consistent performance in demanding environments where durability and ease of maintenance are critical.
Manual Pinch Valves are commonly selected for installations where automation is not required and where straightforward, dependable flow control is preferred.
