Pinch Valve is made up of two parts: the upper side is the body, and the lower side is the connection that can hold the pipe. Keyto pinch valve has three series. The mainly different is the port size. The port size means the pipe diameter you want to use.

In addition to port size, we have many functions to choose from. like single port or dual port, and different installations and different voltages to meet your unique needs.

Pinch Valve Working

The working principle of a pinch valve, specifically a micro pinch valve or miniature pinch valve, is based on the concept of pinching and releasing a flexible tube to control the flow of fluids. Pinch valves are commonly used in various industries, including medical applications.

A micro pinch valve consists of a flexible tube made of materials such as silicone or elastomers. The valve body comprises a housing that holds and supports the tubing. At the heart of the valve is the pinch mechanism, which is typically actuated by a pinch solenoid valve or a similar actuator.

When the pinch solenoid valve is energized, it applies force to the tube, pinching it shut and sealing off the flow of fluids. This prevents any passage of fluids through the tube. Conversely, when the solenoid valve is de-energized, the force is released, and the tube reverts to its natural position, allowing the fluid to flow freely.

This working principle offers several advantages, especially in medical applications, as it provides a complete seal when the valve is closed, ensuring no leakage or cross-contamination. It also eliminates the need for additional sealing components, such as gaskets or O-rings.

Micro pinch valves are known for their compact size, precision, and reliability. They are particularly suitable for applications where space is limited, or when precise control of fluids is required, such as in medical devices or diagnostic equipment.

In summary, a micro pinch valve operates by pinching and releasing a flexible tube through the activation of a pinch solenoid valve. This mechanism allows for precise control and shut-off of fluid flow, making it an ideal choice for various industries, including medical applications.

Pinch Valve For Tubing

A pinch valve is a type of control valve that operates by employing a pinching action to either close or open the flow of fluid or gas through a full bore or fully ported passage. A solenoid pinch valve, on the other hand, is a device that is operated by a solenoid, specifically designed to electronically open and close tubes to control the flow of liquids or gases.

By energizing the solenoid, the plunger is either retracted or attracted, thereby either opening or closing the flexible tube. This type of pinch soleniod valve is particularly well-suited for applications that require frequent changes to the flow path because only the easily replaceable tubing comes into contact with the flowing media.

Our solenoid pinch valves are designed with reliability and versatility in mind. With their efficient operation and precise control, they are suitable for various industries and applications that demand accurate flow regulation. From pharmaceutical manufacturing to industrial processes, these valves ensure optimal performance and reduce the risk of contamination.

The advantage of our pinch solenoid valves lies in their easy installation and maintenance. The replaceable tubing simplifies maintenance procedures, allowing for quick replacement and minimizing downtime. With their robust construction and durability, pinch valve selenoid can handle a wide range of fluids and provide long-lasting performance.

Choose our solenoid pinch valves to experience efficient flow control and enhance your operational processes. Benefit from their reliable performance, versatile application, and easy maintenance. Take control of your flow with our innovative solenoid pinch valves today.

FAQs of Pinch Valves

  • Can a solenoid pinch valve regulate flow?

    The solenoid pinch valve cannot be used to regulate flow because it is only available in two states, fully open or fully close, and the degree of opening cannot be adjusted at will.

  • How doe s a pinch solenoid valve stop flow?

    Two types of solenoid pinch valves are available: N.C. and N.O. 

    Normally open valve(N.O.): the solenoid is powered to drive the pressure plate action, then the pressure plate clamps hose tightly, so as to stop the flow. Normally open valve(N.C.): the initial state of a normally close valve is that of a stop-flow, and the stop-flow principle is the same as that of a normally open valve. The difference is that normally open valve stops flow when powered on and normally closed valve stops flow when powered off.

  • What are the components of solenoid pinch valve?

    Main components of the solenoid pinch valve: solenoid, valve body, spring, moving iron core, hose pressure plate, mounting plate.
