All You Need to Know About Proportional Pinch Valve


Usually, the proportional pinch valve is used in the industrial process because of its long life span and better performance than the mechanical valves. With this hydraulic proportional valve, you don’t need to fear the corrosion in the pneumatic pinch valve. The main reason behind its popularity is that there isn’t any use of metal in the closing circuit of the pinch valve. It uses only the rubber and air in the closing circuit of the valve. The pneumatic valve sleeve and housing open and shut the circuit completely. 

The Quick Response of the Valves:

The proportional pinch valve closes rapidly when the system supplies the high-pressure air. The proportional flow control valve begins to open when the air pressure is distributed in the proportional valve. The process of opening and closing the proportional pinch valve is automated and can also be controlled remotely, increasing the whole system’s efficiency. 

Various Parts of The Pneumatic Pinch Valve:

There are different components of the pinch valve, and these components work in the operational sequence that makes an ideal choice for the industrial application. The long life span performance of the proportional pinch valve becomes mandatory because there is no fear of corrosion & contamination of the pneumatically operated proportional valves. The major three components of the pressure controlling valve are:

A Housing of the Valve: 

The pneumatic proportional electric valve housing is considered a frame in which the whole hydraulic system & rubber sleeves are fitted. Actually, this housing offers the shape and size of the valve.

Rubber Sleeves:

In the pneumatic valves, the rubber sleeves are placed in the frame or housing of the hydraulic flow control valve. In a few pneumatically operated pressure control valves, the rubber is used as in some of the valves, and the air is used for its operations. 

End Connection of Valves:

The electronic proportional valve is connected with its end connections and is bolted, screwed, or threaded at the setpoint to provide support.


What Exactly is An Electronic Control Valve Function:

The proportional flow valve is defined as an electronically controlled valve. It uses a solenoid that compromises the electrical coil with the moving ferromagnetic core in its middle. The plunger gets closed by the tiny component called orifice when it is in the resting position. The electric current flows from the coil that produces the magnetic field.


In this article, we have provided all the information related to the pressure-controlling valves. The information we provide is enough for you to decide on purchasing pinch valves for the pressure regulation. We might have some concerns about what is the function of the proportional pinch valve. The answer to this question is that they are best suited for the inflow & outflow applications. Another benefit is that these proportional valves don’t have direct contact with liquids and gasses. This is the reason why the risks of contamination & rusting are reduced with the passage of time. These pressure-controlling regulators are known to be long-lasting devices that work great.
