Type A - Pneumatic / Hydraulic

Ideal valves for shut off or control applications that involve abrasive or corrosive slurries, powders, or granular substances.

Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed on the sleeve. Modulating the air pressure within the annular space between the body and the sleeve can open, throttle or close the valve.

The valve body acts as a built-in actuator, eliminating costly pneumatic, hydraulic or electric actuators.

Type A-PRV - Pressure Relief Valve

Type A-PRV Pressure Reducing Valve protects pumps & motors from damage.

It consists of a pinch valve in combination with a pressure gauge.

The pinch valve is installed in a bypass line of a pump. If the pump becomes blocked, the increased pressure forces the valve to open which provides a pressure relief allowing the sewage to bypass the pump until the blockage is cleared. Then the valve resets itself in it’s closed position.

Series 2600 Miniflex - Pneumatic

Manufactured on the same design principles as Type A valve (above), Series 2600 Miniflex valves are designed with threaded end connections, enabling use on small lines (1/8”-2”).

Series 75 / Series 70 - Manual

Ideal valves for applications that involve abrasive or corrosive slurries, powders, or granular substances.

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

Ideal valves for shut off or control applications that involve abrasive or corrosive slurries, powders, or granular substances.

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

Ideal valves for shut off or control applications that involve abrasive or corrosive slurries, powders, or granular substances.

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.

Y-Flex Diverter Valve - Pneumatic

Y-Flex is designed to replace two separate valves and a 'Y' connection, simplifying installation.

Each leg of the diverter can be operated independently of the other leg, in either on-off or modulating mode.
