Pinch valves are used in a variety of applications

Pinch valves are used in a variety of applications. They are especially useful for handling slurries and granular materials. These types of valves can also be used in laboratory equipment. They have many advantages over other valves, such as ease of use and reliability. They are also suitable for high hygiene control. However, pinch valves have a limited range of operating pressures. They should be avoided for vacuum applications, as they can collapse with the pressure.

The pinch valve has three major components. The pinching mechanism, the body, and the rubber sleeve. The pinching mechanism pushes the middle of the sleeve, which blocks the flow. The body is made of a synthetic material. The material is abrasion resistant and can tolerate temperatures and application conditions.

The sleeve is usually made of natural rubber or nitrile. In certain applications, they can be made of silicon, Viton, or other suitable synthetic polymers. Abrasion resistance can also be improved by lining the sleeve with polyurethane. A pinch valve can also be fitted with clamps to secure the sleeve.

A pinch valve is an effective and inexpensive way to control the flow of media. The evr valve pinching mechanism can be controlled manually or pneumatically. It is an excellent choice for laboratory equipment or in processes where solids need to be isolated. The valve is available in a wide range of sizes, including those that fit standard flanges. In some cases, a pinch valve can be used to connect two pipes, allowing the user to choose between a straight and an angled connection.

There are several different pinch valve types, each with different advantages. Most pinch valves are designed for the optimum flow of slurries, and they have a tight shut-off. In addition, they have a full bore for the flow media. They are also available with end connections, providing stability. They are suitable for many kinds of media, including water, chemical solutions, sewage, and food grade. They have been used for many years in concentration plants. They are also popular in pharmaceutical, food, and washdown applications.

The pinching mechanism is a mechanical device that can be operated by turning a hand wheel. In addition to manual operation, there is also an air-operated model. These models can control most abrasive products. A pinch valve is the most practical solution for flow control. They offer a reliable and cost-effective method for controlling the flow of slurries.

Pinch valves are typically used in pipelines that handle corrosive products. They can be fitted with end flanges to allow flush fitting with the transport tubing. They have a throttling range of 10% to 95% of the rated flow capacity. A pinch valve can be used in a number of applications, such as clinical analyzers, IV drug delivery systems, and more. They are easy to clean and have a low price.

Some pinch valves have a conical sleeve that increases the linearity of the control curve. They are available with extended hubs for ease of installation.
