The pinch valve is a type of control valve that uses a pinching effect to prevent fluid flow. It is available in full bore and fully ported designs and is used in applications where there is a need to control the flow of fluids. It has many advantages over other types of valves, and is highly versatile.
Enclosed-body pinch valve
The enclosed-body pinch valve is the most common type of pinch valve. It has an enclosed body to protect the valve sleeve from the media. These valves range in diameter from NPS 1″ to NPS 1″ and feature a durable, self-cleaning sleeve to minimize abrasion and corrosion. They also offer repeatable linear flow control and tight shutoff.
The enclosed-body pinch valve has a large range of applications and is ideally suited to aggressive media. Due to its low maintenance requirements, it is an excellent choice for harsh industrial environments. The enclosed body design also allows the valve to be used with a variety of piping materials.
The OV Series Mechanical Pinch Valves from AKO are designed to handle a variety of materials, including fibrous and corrosive products. They feature a full-round or double-pinch centerline pinching mechanism, with through-hole flanges. These valves are typically available in sizes of 1/2″ to 10″.
The pinch valve is operated with a handle similar to a gate valve. The handle turns a lead screw which closes or opens the valve. The mechanism is usually comprised of two flat metal bars that are squeezed together by a lead screw.
Pneumatically operated pinch valve
A Pneumatically operated pinch valve is a type of pneumatic valve that is used to control the flow of fluids. These valves have a decomposition-resistant design and are suitable for applications in various industries. They are used for sludge control, raw sewage control, and flow equalization. They can also be used in thickeners.
A pneumatically operated pinch valve is commonly used in difficult-to-access media. These valves are usually brass chrome-plated and have no direct contact with the media. The pinch valve maximum pressure to which they are applied should not exceed the limit illustrated on the diagram. This valve has a size 1″ inner sticking socket, a sleeve made of EPDM-rubber, a 3″ actuator diameter, and two springs. A manual override is available for greater control of the pinching force.
Applications of pinch valve
A pinch valve is a special kind of valve that is used for controlling the flow of fluids in different types of equipment. These valves are usually made of metal and can handle abrasive or corrosive media. Their low maintenance and high performance make them suitable for various industrial applications. They can be installed directly into the fluid line or attached to a tee. They can also be used for proportional control applications.
The materials used in pinch valves are important for the correct operation. For example, the material used for the body should be lightweight and have high abrasion resistance. The sleeve material can be natural rubber, EPDM, butyl rubber, and silicone. Pinch valves can be made from a variety of materials, including aluminum, plastics, and silicone.
