Pinch valves are a type of valve that is designed to control the flow of a fluid. They are used in a variety of different industries, including power, oil and gas, petrochemical, food and pharmaceuticals. These valves are available in a number of different configurations, and can be fitted with pneumatic or electric actuators.
Unlike ball valves, piston valves and gate valves, pinch valve manufacturers are simple in design, meaning that they can be used in a wide range of applications. They are also relatively easy to install and maintain.
They are a great choice for bulk handling and product transporting applications, as they do not require any mechanical parts or bearings. They also have a low maintenance cost and can be operated by hand or through the use of pneumatic or electric actuators.
These valves are often used in chemical process control, sewage treatment, and mining. They have a very high level of wear resistance, so they are ideal for handling corrosive or abrasive fluids.
The key to the longevity of these valves is their rubber sleeve, which provides an extremely tight shut off around the solids in the medium. The sleeve is made of a very high quality rubber, and it is able to resist the kinetic energy of the solids without breaking.
Another major advantage of these pinch valves is their rebound resilience, meaning that the sleeve will quickly and completely return to its compressed lip shape when air pressure is removed. This helps to ensure that they can be opened and closed repeatedly, and therefore last longer than other valves.
Pinch valves are suitable for a variety of applications, but are especially useful when the medium has a high concentration of metals. This is because their sleeve is completely isolated from the medium, preventing corrosion or metal contamination of the fluid or slurries.
Besides their ease of installation and maintenance, pinch valves are also a good choice for hygienic applications. They can be used in a variety of ways and are often installed inside stainless steel equipment, which makes them an attractive option for pharmaceutical or biopharm manufacturing processes that require sterilization or full washdown cleaning procedures.
They are also commonly used for pipelines that contain abrasive or corrosive fluids. The sleeve is able to contain the flow media and isolate it from the environment, so it can be used for all types of liquid, solid or slurry applications.
Some of these pinch valves are even suitable for carrying pulp, dry and wet powder and crystalline material mediums. They are also resistant to acid and alkali, which means that they can be used in a range of chemical processes.
Pinch valves are a great choice for the sanitary and industrial sector, as they are an ideal solution for handling corrosive or abrasive liquids and slurries. They are also extremely flexible and can be used for any type of medium, which makes them a versatile solution for various industrial applications.
