What You Should Know About Rubber Pinch Valve Components

If you’re thinking about getting a pinch valve, there are a few things you should know before making the purchase. One of the most important things is the quality of the inner bushing. Choosing the right inner bushing will make a huge difference in the service life of the pinch valve. Luckily, pinch valve manufacturers are doing continuous load tests to ensure the quality of the product and extend its service life as much as possible.

Rubber sleeve

The heart of any pinch valve is the rubber pinch valve sleeve. These sleeve pieces are usually hand-built and consist of layers of rubber with fabric inserted between the layers. These sleeves are then ground to the diameter and length needed for the valve. The design and construction of the sleeve are critical to the valve’s closing and opening capabilities, as well as its service life. These sleeve pieces are available in a variety of sizes ranging from DN 80 mm up to DN 300 mm.

Rubber sleeve material

Regardless of your application, the pinch valve sleeve is an important part of the valve. It will come in contact with the flowing fluid, so it should be made of a material that is resistant to abrasion. Depending on your specific requirements, different elastomers are used to make the sleeve. Some materials include natural rubber, EPDM, and NBR. Other options include silicone, butyl, and PTFE.

Rubber sleeve liner

A pinch valve sleeve liner is a highly versatile valve accessory. This type of valve sleeve liner features a double-wall construction for additional protection from abrasion and corrosion. The design is easy to install and is cost-effective. ThisĀ https://evrproducts.com/products/pinch-valves/ sleeve liner also features an orifice that prevents cavitations. Its sleeve is available in a variety of materials.

Rubber sleeve body

The sleeve body of a pinch valve must be flexible to handle the flow of the medium. Generally, the body material is rubber. This material should be lightweight, with a good abrasion resistance and a high degree of chemical and pressure resistance. It can be made from a variety of materials, including EPDM, NBR, silicon, and natural rubber.


A high-quality EPDM rubber pinch valve can be used in a variety of applications. Its design enables quick and easy valve replacement, reducing downtime and production costs. This valve is also suitable for regulating fluid flow and has an extremely long service life.


A Neoprene pinch valve is a type of pressure valve that has a rubber or synthetic sleeve that comes in contact with a flowing fluid. It has a flexible sleeve that resists abrasion, and it is a lightweight material. Other materials that can be used for a pinch valve include EPDM, NBR, natural rubber, silicone, food-grade rubber, butyl, and PTFE.
