Rubber pinch valves are used in a variety of industrial applications. They have a wide range of applications in cement, glass, paper, electronics and food industries. A typical design is a hand-built sleeve made of rubber with an actuator pushing on the sleeve to close it tightly. Their simple construction makes them a popular choice for a variety of applications.

Truco is a fluid handling specialist and is a leading South African manufacturer of hand-built rubber pinch valve sleeves. These valves are available in a variety of diameters from 50mm nominal to 1200mm nominal, and can be custom-built to meet your exact specifications. Depending on your specific needs, different elastomers can be used to create the best possible fit and performance.

A pinch valve sleeve consists of a molded rubber or synthetic sleeve with a pinching mechanism embedded in the sleeve. Other operating parts of the valve are external and not in contact with media. The sleeve is reinforced with fabric for added strength and durability. The sleeve’s smooth walls minimize turbulence and line vibrations and are bubble-tight. The sleeve can be easily replaced or repaired if necessary. Pinch valves do not require packing, which is a major benefit.

Pinch valves are used in a variety of non-contact applications, including sewage treatment and pipelines handling corrosive media. They are also commonly used in single-use disposable systems. Compared to other types of valves, pinch valves have fewer parts, including the stem and body. Pinch valves that are non-wetted have no moving parts, while those that contact fluids have more options for materials and designs.

RVA series pinch valve has a patented extension shaft

The patented extension shaft of the RVA series rubber pinch valve enables the valve to counteract large tensile and bending forces. This valve meets the standards of DIN 3205 and ASME B16 and is available in a variety of materials, including natural rubber, EPDM, Viton and silicone resin.

The patented extension shaft extends the pinch valve’s lifetime by up to 50%. Its internal opening aid device helps in opening and closing the valve in an accurate and reliable manner. It is suitable for non-corrosive media and can withstand temperatures up to 80 degrees Celsius.

The patented extension shaft enables the RVA series rubber pinch valve to be used in a wide variety of applications. ThisĀ find patented extension shaft allows the RVA series rubber pinch valve to be mounted anywhere on the shaft without the need for a flange. This design makes it a versatile piece of equipment that can be used in a variety of industries.

RVA series pinch valve is available with a patented extension shaft

The RVA series rubber pinch valve uses a patented extension shaft that is capable of effectively compensating for large bending and traction forces. This patented extension shaft is available with a variety of elastomers, including EPDM, neoprene, silicone resin, and Viton. These pinch valves are also designed with a wear warning system.

The RVA series rubber pinch valve is made with three main components: the rubber sleeve, extension shaft, and end connections. The rubber sleeve fits into the housing from inlet to outlet. This is the only part of the valve that comes into contact with the media. The end connections provide support for the pinch valve.
