When considering a pinch valve, you need to consider several factors. First, the material used should be suitable for the application. For example, the material should be able to tolerate the temperatures of the application. The material also should have the necessary wear resistance. Another important factor is its design: a pinch valve features a streamlined flow pattern, which reduces wear on the sleeve.
Natural rubber
A pinch valve is a type of valve that closes over the area of contact. These valves are used for a wide range of fluids and are often suitable for food grade applications. They do not have a metal surface and therefore are non-corrosive.
EPDM
An EPDM rubber pinch valve is a versatile and durable piece of equipment. It is easy to install and maintain, thanks to its modular design. It is also easy to change the https://evrproducts.com/products/pinch-valves/ valve membrane on site. It is also corrosion-resistant and has good bearing pressure. Moreover, EPDM rubber is ideal for use in environments with high temperatures and high pressure.
Neoprene
Pinch valves have many favorable properties. They offer a cost-effective solution for controlling the flow of media in a variety of systems. These valves have a rubber sleeve to prevent contamination of other components of the system. This makes them highly desirable in many industries. The valves are typically used in pipelines and in sewage treatment systems. They are also frequently used in single-use disposable systems. The body of the valves is often made of stainless steel or polyamide blend. The materials used in the sleeves of the valves can be varied. Some models are designed with conical sleeves to improve linearity of the control curve.
Electric motor actuators
Electric motor actuators for rubber pinch valves are available in different configurations and can be manually operated or automated. They are generally reversible and use a high-speed motor. They control the valve’s open and close functions using a torque that is determined by the valve’s position and the duty cycle of the motor. In some applications, limit switches are also used to automatically shut off the motor at a predetermined fully-open or fully-closed position.
Quik-Stop tubing
Pinch valves are available in a variety of sizes and styles to meet the needs of biopharmaceutical and pharmaceutical industries. They can handle high sold content, heavy contaminants, and high viscosity fluids. They can be manually or electrically operated and come in stainless steel.
Enclosed-body
An enclosed-body rubber pinch valve is used to control the flow of fluids, gases, or other media. The valve body consists of a molded rubber or synthetic sleeve containing the pinching mechanism and the rest of the operating parts. The internal sleeve is reinforced with fabric. The body has smooth walls to minimize turbulence and line vibration, while the tight seal ensures a leak-tight shutoff.
