The Series 4400 High-Flow Capacity Pinch Valve is ideally suited for hard-to-handle fluids, especially slurries. Solids in the flow make operation of other types of valves - such as ball, plug and butterfly valves - problematic. The Series 4400 handles tough fluids easily with its full port design.
Series 4400 Pinch Valves provide excellent flow control compared to other valves due to their simple yet effective design. In addition, the sleeve is the only part of the valve exposed to the line process, eliminating maintenance and/or corrosion of the more expensive mechanical components. The heart of the Series 4400 Pinch Valve is a durable rubber diaphragm spool, available in a wide variety of elastomers - including Teflon lined - suitable for any application.
Automated operation is achieved by installing any pneumatic or electric, quarter-turn actuator control package to the stem of the Series 4400 Pinch Valve. Tapped mounting holes are provided for assembling the actuator mounting bracket to the valve. Manual operation of the Series 4400 Valve is accomplished with a 6-position, notched detent plate and spring-loaded lever assembly. During operation of the valve, two opposing gear-driven cams act on the sleeve, providing flow control over the entire 90 degrees of valve stem travel. The Series 4400 Valve exhibits negligible pressure drop in the open position and bubble tight closure - even around solids - in the closed position.
