PNEUMATIC PINCH VALVE

We are a pneumatic pinch valve manufacturer. Pneumatic pinch valve is mainly composed of upper and lower cast iron or cast steel body, rubber tube sleeve, size valve stem, ram, upper and lower guide post, pneumatic device and other parts. Among them, the body material is various, including cast iron, aluminum alloy, carbon steel, etc.; The rubber tube sleeve contains a reinforced cord layer to enhance its pressure and wear resistance. The stem material is usually cast copper or carbon steel.

The working principle of the pneumatic pinch valve is based on air pressure control. When the air source enters the compressed air, the piston in the cylinder is pushed by the pressure, so that the piston rod extends or retracts. The valve disc can be opened or closed by connecting the piston rod with the valve disc. When the air source stops supplying gas, the return force of the spring retracts the piston rod, and the valve disc is closed under the action of the spring force. When the control medium is not input, the cavity between the rubber sleeve and the valve body is communicated with the atmosphere, and the rubber sleeve is tensified outward by the fluid pressure. When the control medium enters the cavity between the tube sleeve and the valve body, the tube sleeve deforms under the pressure of the medium.

1.No leakage: The product has no sealing point, the control medium space and the valve channel are completely isolated, so there will be no internal and external leakage.

2.Particle corrosion resistance: relying on rubber sleeve deformation to achieve opening and closing, even if the fluid contains solid particles or fiber impurities will not block, can be completely and quickly wrapped closed.

3.Wide application: simple structure, can replace large volume, complex structure of the valve, especially suitable for explosion-proof requirements.

4.High efficiency and longevity: The unique rubber tube sleeve with reinforced cord fabric can withstand high frequency of opening and closing operations, acid, alkali and chemical media resistance, with a long service life.

5.Simple installation: the valve installation is non-directional, the use of pipelines without cleaning, once the rubber sleeve is damaged, the replacement is simple and rapid.

6.Easy control: local or remote automatic operation control can be achieved according to needs.

1. Occasions requiring high sealing

No leakage features: no sealing point, the control medium space and the valve channel are completely isolated to avoid internal and external leakage.

2. Fluid handling containing solid particles or fiber impurities

Particle corrosion resistance: relying on rubber sleeve deformation to achieve opening and closing, even if the fluid contains solid particles or fiber impurities, it can be quickly wrapped and closed to ensure the smooth passage of fluid.

3. Wide range of industrial fields

Multiple industry applications: pneumatic pipe clamp valve is widely used in petrochemical, fertilizer, metallurgy, power, construction, pharmaceutical, food, wine and other industries of the pipeline system.

4. Need to explosion-proof occasions

Simple structure, only by three main components, can replace large volume, complex structure of the valve, especially suitable for explosion-proof requirements.

5. Frequent opening and closing situations

High efficiency and long life: The unique design of rubber tube sleeve with reinforced cord makes the pneumatic tube clamp valve able to withstand high frequency of opening and closing operations, and is resistant to acid, alkali and chemical media corrosion, and has a long service life.

6. Convenient installation and maintenance occasions

Simple installation: the installation is non-directional, and the use of pipelines does not require cleaning.

Easy control: local or remote automatic operation control can be achieved according to needs, improving work efficiency and convenience.
