Series 5700 Control Pinch Valve

Red Valve’s Series 5700 Control Pinch Valve is a cost-effective choice when centerline valve closure is required.

The Series 5700 offers a 100% full-round port opening and Class V shut off.

In throttling service, the 5700 provides true feedback positioning and accurate, repeatable, variable venturi flow control.

There are no seats to grind, no stuffing box to repack and no packing gland to adjust.

The rugged, self-cleaning elastomer sleeve isolates all mechanical parts of the mechanism, so the operating torque remains constant.

Full-port opening and centerline closure is extremely important for larger sized pinch valves in abrasive and high-velocity applications.

Patented by Red Valve Company in 1983, the Series 5700 with centerline closure outlasts all other types of gate, plug or ball valves on control of abrasive and corrosive slurries.

Cone Sleeves can be specified to further enhance control performance and match the exact Cv level desired.

True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft.
