Pinch Valve

Magnetbau Schramme - Your specialist for pinch valves

Electromagnets designed as pinch valves are mainly used in medical and analytical technology, in chemical processing and in measurement and control technology as well as for the reliable control of difficult materials. Other areas of application are liquid filling systems in the food sector.

With the choice of high-quality materials and customised development, it is possible to realise products in series and in any design with a wide range of specifications.

How do pinch valves work?

Pinch valves can be controlled by compressed air, water pressure, fluid or electromagnetically and usually consist of an elastomeric hose section, a valve body and a mechanism that compresses the hose.

When the mechanism is activated, it presses on the hose and squeezes it. This stops or reduces the flow of the liquid or gas inside the hose. When the pressure on the hose is released, the hose can return to its original shape and the flow continues.

Features & Advantages of Pinch Valves

A pinch valve offers a number of features that make it attractive for various applications.

• No valve parts in contact with the medium: The medium only comes into contact with the hose, which means that no contamination can occur in the pinch valve.
• Quick unrestricted assembly: Space-saving design and installation in any position enables easy assembly in practice. Furthermore, there is no interference with the medium when replacing the hose clamp valve.
• Low power consumption: The pinch valve requires only 3 watts of energy when switched on.
• Durability of the components: We install high-quality components in order to be able to deliver the highest quality to our customers.
• Maximum flexibility: Flow can be in both directions and can be used with 1 or 2 hoses.
• Low maintenance: As there are no moving parts in the pinch valve that come into contact with the medium, wear is low and maintenance requirements are minimal. This reduces operating costs and ensures a longer service life for the valve.
• The range of electromagnetic pinch valves: 1.5 mm to 12 mm hose diameter.

Disadvantages of pinch valves

Pinch valves have few disadvantages.

For example, pinch valves are unsuitable for high temperature applications. Due to the elastomeric property of the pinch valve sleeve, the pinch valve is not designed for high temperature applications.  The limiting factor is the silicone tube. Temperatures up to 200 degrees can be realised.
