  • No packing to maintain, ever
  • Sleeve is the only wetted part, reducing maintenance and alloy body costs

Materials of construction

  • Cast iron body, ANSI 125/150
  • Sleeve available in Pure Gum Rubber, Neoprene, Hypalon, Chlorobutyl, Buna-N, EPDM and Viton


Type M manually operated pinch valves are reliable, maintenance-free, cost-effective valves designed for slurry and abrasive and corrosive-chemical applications. There are no seats to grind, no stuffing boxes to repack and no packing glands to adjust. The pinching action is on centerline, so the valve closes on a smooth venturi.

The heart of this unique valve is the durable, flexible rubber sleeve which is reinforced with high-strength fabric. The sleeve, which is the only part of the valve exposed to the line process, eliminates maintenance and the need for expensive materials. Additionally, valve operation will not freeze, and operating torques remain constant. AWWAnuts, chainwheels, stem extensions and bevel gear actuators are also available.
