A rubber pinch valve is a type of valve used to control pressure in bulk materials and can be used in a variety of applications. This type of valve is made of all-quality elastomers and is suitable for a wide range of bulk materials and temperatures up to 80degC. They are also safe for food products. A rubber pinch valve can have an inner bushing made of nitrile rubber, fluoro rubber, or silicone resin.
Membrane
There are several types of rubber membranes available for use in rubber pinch valves. The most common type is made of natural rubber which offers high elasticity and flexibility. This material is also the best choice for applications involving abrasive media. It also offers the longest lifespan. Other types of rubber membranes include EPDM and Nitrile. All three types are FDA approved and have different temperature ratings.
Diaphragm
Diaphragm valves have a number of advantages. This https://evrproducts.com/products/pinch-valves/ type of valve is used for fluid handling in applications where the flow rate is low. They can also handle low pressures. Because of this, many manufactures focus on diaphragm valves that are smaller in size. However, the material used for the diaphragm is critical.
Full bore
The full bore rubber pinch valve has a variety of benefits over conventional valves. Its unobstructed flow path, low friction, and laminar flow design help control and regulate the flow. Its rubber sleeve also minimizes turbulence, resulting in less pressure loss. Its sleeve is also lined with Linatex for protection against harsh process environments. Its low friction, full bore design, and dual action pinch mechanism also contribute to the valve’s high flow capacity, predictable linear flow performance, and low sleeve wear.
Liner motion
A pinch valve has several advantages over other types of valves. They have an effective throttling range and can be used in a variety of applications. They are effective in controlling the flow of liquids, solids, and slurries. Because they have no moving parts inside, they also have a low maintenance requirement. However, they are not suitable for applications requiring high holding forces.
Operating pressure
When operating a rubber pinch valve, the pressure differential between the valve sleeve and body must be precisely controlled. It should be between 2.5 and 3.5 BAR. More than that may deform the sleeve. If the pressure differential is too high, it can result in valve failure. Keeping the pressure below this range will prolong the life of the sleeve and minimize the risk of deformation.
Cost
There are a number of factors that determine the cost of a rubber pinch valve. These include the materials used to manufacture it, the size, and the location of the valve. Generally, a rubber pinch valve will have three major components: the rubber sleeve, the valve body, and the pinch valve sleeve. The rubber sleeve comes in many different types, including abrasion resistant NR, neoprene, EPDM, gum, and Butyl. If you’re unsure of what type of sleeve to buy, you can consult the manufacturer of the valve.
