Type A - Pneumatic / Hydraulic

Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed on the sleeve. The valve body acts as a built-in actuator, eliminating costly pneumatic, hydraulic or electric actuators. Modulating the air pressure within the annular space between the body and the sleeve can open, throttle or close the valve.

Series 75 / Series 70 - Manual

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. The design principle is very simple - two mechanical pinch bars open and close the elastometer sleeve. The pinching action is on centerline, so the valve closes on a smooth venturi and is self-cleaning.

Series 5200 - Pneumatic

A heavy-duty pinch mechanism positions the sleeve for accurate control over a wide flow range. Particularly in slurry applications, the stroke adjustment allows for fine-tuned flow control as the sleeve wears.
True feedback positioning is accomplished through the direct linkage of the pneumatic positioner to the valve stem shaft. Accurate small-change response signals to the positioner greatly enhances control accuracy.

Series 5200E - Electromechanical

Series 5200E electrically actuated valves are actuated by AUMA, Limitorque or Rotork electric operators as a standard. Other electric motor operators are also available.

Weirflex 70 CSO - Manual / Electromechanical

The Weirflex 70 CSO is designed to specifically meet the needs of stormwater and combined sewer systems. The valve features a full-port opening for unobstructed flow when in the open position. To control the rate at which stormwater enters a collection system, the valve is closed from the bottom, creating an adjustable weir. The weir can be closed up to 96% of the total pipeline diameter. This allows operators to adjust for seasonal rainfall changes, wet-weather conditions, storm events or changing population demands.
