Dual Valve (DFV)

The DUAL valve operates on the discharge side of the pump. As the flow through the pipeline starts or stops, the ball automatically rises or falls, opening or closing the valve. The handwheel is there to lock the ball in position. The handwheel can be used to isolate, but with back pressure. The Dual valve can work in the horizontal and vertical position.

Free Flow Valve (DFFV)

DUAL‘s Free Flow Valve operates on the discharge side of the pump as the flow through the pipeline starts or stops, the ball automatically rises or falls, opening and closing the valve. This occurs without noticeable shock or hammer, regardless of the line pressure or the speed of closure.

Slimline Free flow Valve(DSFFV)

DUAL‘s Slimline Valve’s heart is a reinforced urethane or rubber ball. The unique design of the valve allows free movement of the ball. The ball lifts completely out of the flow when the pump starts and allows free flow of liquid without any interference. As the pump stops, the ball falls and positively locates in the seat due to its own weight and back pressure of the liquid. This results in dropless sealing.

Dual Pinch Valve Open Body Type (DPVO)

Dual’s Pinch Valve consists of a tough, but flexible bore sleeve, which forms part of the pipeline. The valve is closed mechanically via movement of the Pinch Bars located on the opposite sides of the sleeve. The core of the Dual Pinch Value is the sleeve – this sleeve is reinforced with high-strength fabric. The valve are well suited for on/off and throttling control applications where scale build up is a problem.

Straight Through Pinch Valve (DSTPV)

DUAL‘s Straight-Through Pinch Valve consists of a tough, but flexible full bore sleeve, which forms part of the pipeline. The valve is closed mechanically via movement of a pinch gate located above the sleeve. The core of the Dual Straight-Through Pinch Valve is the sleeve. The valves are well suited for on/off and throttling control applications involving slurries, powders, liquids, granulated materials and applications where scale build is a problem.

Slurry Knife Gate Valve (DSKG)(Bray)

DUAL‘s Slurry Knife Gate Valve is built with a cast SG Iron GR. 42 or fabricated body and features a heavy-duty stainless steel blade. Removable sleeves on either side of the blade provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry.

Pump Protection Valve (DPV)

DUAL PUMP PROTECTION VALVE (DPV) DUAL ‘s Pump Protection Valve has been designed and manufactured to provide protection against excessive fluid temperature rise, within the pump housing. Low flow conditions can cause flashing, cavitation, vibration, bearing failure and damage to mechanical seals and pump housing. The DPV valve is fitted to the suction side of the pump. The valve can be used to control or limit the pressure in a system or vessel.
