Pneumatic and solenoid pinch valve suppliers in UAE
How does a pneumatic pinch valve work?
Pneumatic pinch valves is spring-loaded, air-operated valves that are used to relieve pressure in pressurized piping systems. Pneumatic systems use compressed air as the medium for transferring pressure between pipes. If a valves is pinched, it releases the air pressure in the system. If the Solenoid pinch valves is open, it lets the air out of the system. Pneumatic pinch valves are designed to close when a pressure differential of 1.5 to 2.0 pounds per square foot exists between the piping system and the valves. If the pressure in the piping is higher than 2 psi above the system pressure, the pneumatic valve will close, relieving the higher pressure at the other end of the piping system.
A manual pinch valve is a 2/2-way valve designed to shut off or control the flow of corrosive, abrasive, or granular media
What is a manual pinch valve used for?
A Manual pinch valves is used in situations where the system pressure is relatively constant. The typical application is to connect a water system to a pressure vessel for controlled flow. The controlled flow water pressure is delivered to the vessel via the manual valves. Another example is a controlled flow system. This can be found in many food processing plants. In this environment, the customers’ food ingredients are blended and stored in tanks and racks. As components are needed, they are drawn off the tanks and processed in the process lines. The process lines are usually connected to the customer’s silos via an Air operated pinch valves. This is used to control how much liquid is drawn off the storage tanks and sent to the customer’s silos.
A Pinch control valve is a full bore or fully ported type of control valve which uses a pinching effect to obstruct fluid flow
What are the advantages and disadvantages of a pinch control valve?
The main advantage of an Electric pinch valves is that it is a quick and easy solution for relieving pressure in a system when a burst pipe or other damage has occurred. The disadvantage is that it is not a fail-safe system. If the pressure in the system is higher than the setpoint, the valves will open. If the pressure in the system is lower than the setpoint, the valves will close. In this case, the customer’s ingredients will be trapped in the process lines and not be processed. If the pressure in the system is too low, the Pinch control valves will close and trap the customer’s ingredients in the storage tanks. If a valve with a low setpoint is used, the potential for damage and loss of customers’ ingredients is great.

Can a pinch tube valve regulate flow?
No. A valve with short stroke seals against the high-pressure side of the Pinch tube valve. When the valve is opened, the high-pressure side of the valve pushes against the valve seat, causing the valve to close. This action seals the line and stops the flow of the product. When the valve is closed, the lower-pressure side of the valve pushes against the tube, causing the opening of the valve and the release of the product. When the valve is open, air pressure is building in the system. When the Flow control pinch valve closes, the low-pressure side of the valve opens the valve.

How do you test an air operated pinch valve?
Air-operated valves should always be tested before they are used. There are several ways to test an air operated valve. The most common way is to test the valve with a hand-operated spring pressure gauge. Another way is to use a compressed air gauge. This is connected to a flexible hose that is pushed into the valve. The hose must go all the way into the valve so that the gauge has pressure from both sides of the Tubing pinch valve. If the valve does not have a gauge, it can be tested by pushing air through the valve while you hold an object against the valve. If the flow is blocked, the valve should be replaced because it could be leaking.
