Geeplus solenoids are also used in a variety of valve applications, where the solenoid’s plunger is used to control the flow of fluid or air. In the Geeplus Pinch Valve shown, when the solenoid is energized, the plunger retracts, closing the valve. When power to the solenoid is cut, the plunger is released, opening the valve again.

Proportional Options for Greater Control
In some cases, a greater degree of control is necessary than simply opening and closing the valve. For these valve applications, a proportional or semi-proportional solution is often implemented, where the armature moves in proportion to the power of the current. 

Pinch Valves

Pinch valves are used to facilitate the flow of liquid through a tube by opening and closing the flow, without any contact between the liquid and the valve itself. The tube is pinched between a fixed and a moving bar (pinch elements); as these are closed together the tube is pinched closed and the flow is shut off.

The Geeplus range of pinch valves suit a wide variety of applications calling for control of water, air and other non-aggressive fluids across a wide range of industries.

A development of Geeplus’ widely used general purpose solenoid valves, the pinch valves are robust in manufacture and thoroughly reliable in operation. Geeplus is also known as the world’s leading supplier of actuators in medical ventilators.

Typically used with silicon tubing as the carrying device, the pinching is achieved by energizing the solenoid. This cuts off the media in the tube by pinching or releasing the tubing. The fluid can flow in either direction.
