Pinch Valve Information

Pinch valves are a versatile piece of valve equipment. When open, they transmit fluids and are generally bolted between pipe flanges. As the name implies, they are characterized by an oval shape that is created by compressing air, which pinches the tube in the middle and closes the flow at its center. They work with many fluids, and many are designed for food-grade applications.

Simple design

Pinch valves are a type of pressure-controlled valve that transmits fluids when they’re open. They are bolted between two pipe flanges, and compressed air is pushed into the valve body, pinching the tube into an oval shape and closing the flow at the center. Pinch valves can accommodate a wide variety of fluids and are often suitable for food-grade applications.

Simple design is another advantage of pinch valves. They’re easy to engineer as tight shut-off valves, and are usually supplied with a pinch tube contained between the end flanges. This means that if the valve is not closed properly, the pinch tube can be monitored to detect leaks. Pinch valves also offer secondary containment and are well-suited for pipelines containing abrasive slurries or large suspended solids.

Low cost

Pinch valves are a popular choice for a variety of liquid, solid, and slurry applications. They are lightweight and require relatively little maintenance. In addition, they are bubble-tight, allowing users to control flow with a high degree of accuracy. Many types of applications include sewage treatment, food processing, and grit removal.

When selecting a pinch valve, a wide variety of factors must be considered. For example, the material used to manufacture the body should be light and non-combustible with the flow media. Another consideration is the abrasion resistance of the liner. If the material is worn or damaged, it can cause the valve to malfunction, causing the flow of media to be interrupted. Also, if the click this material is too weak, it can develop a memory and protrude into the media stream. A pinch valve is also not recommended for use in vacuum applications, as the media must pass through the sleeve before the valve can open.

Easy to install

Easy to install pinch valves are a simple way to control fluid flow, minimizing tubing wear and minimizing consumable complexity and cost. These valves are ideal for use in the chemical, pharma, plastics and ceramic industries. They are lightweight and easy to install. Pinch valves are also used in environmental technology to control flow and seal waste water, dust and sludge.

Pinch valves are one of the easiest types of valves to install, with little frictional resistance. This means they won’t clog and won’t require expensive maintenance. They are also among the easiest valves to maintain, with a relatively low weight. Pinch valves can be installed and maintained by just about anyone. Typical maintenance requires changing the sleeve, but other than that, they require very little maintenance.

Easy to operate

Pinch valves are used to control the flow of liquids or granular products in a variety of processes. They are reliable, affordable, and easy to operate. They use elastic tubing to create a seal equivalent to the permeability of the fluid. This makes them ideal for a range of processes, including mineral processing, cement production, iron and steel production, and aluminium production.

Easy to operate pinch valves are available with a variety of actuators and features. Single-use models are meant for tubing with IDs ranging from 1/4″ to 1″. They are designed to operate with existing tubing and can be matched to fit existing tubing. They are available with different options, including limit switches and modulating pneumatic actuation.

Easy to maintain

Pinch valves are relatively simple valves that have full bore openings. They’re ideal for fluids containing high solids and abrasive products. They’re also inexpensive, easy to install, and require little maintenance. Their design is based on a simple, two-part design: a valve body and a cylindrical sleeve. These valves are closed by applying pressure, usually generated by compressed air.

In addition to being easy to maintain, pinch valves can be serviced on-site. Because they don’t require special tools, they can be removed from the pipeline, serviced, and reintegrated within a matter of minutes. This prevents long downtimes for the system. Moreover, it’s possible to order replacement parts for a pinch valve without changing the entire valve.
