The threaded flexible tube valve includes a core component inner bushing, a valve body, and two casing covers. The valve body of the pinch valve is composed of the main body and two nip rings. The two rings are inserted into the ends and are sealed between the O-ring and the main body of the valve.
Through the pressure difference of 2-3bar between the medium pressure/working pressure in the valve body of the pinch valve (depending on the quality of the elastomer), the threaded flexible tube valve is closed. When the pressure supply is interrupted and the pinch valve body is ventilated, the threaded flexible tube valve inner bushing is fully opened due to its great resilience.
The following plastic materials can be used:
White polyoxymethylene-plastic steel
Cold-resistant and weathered black polyoxymethylene-plastic steel
Conductive POM-plastic steel
Under normal circumstances, the threaded pneumatic pinch valve adopts an internal thread connection in accordance with DIN ISO 228 standard, or NPT connection. According to customer needs, threaded flexible tube valves can also be supplied with connections required by customers.
Industrial field, possible application fields:
Pneumatic pinch valve, also known as pinch valve, squeeze valve, bladder valve, hose valve, airbag valve, pinch off valve, etc. The pinch valve rubber sleeve (inner bush) is an important part of the pinch valve and the core of the pinch valve. It provides corrosion resistance, wear-resistance, and p Read More »
1. ScopeThis standard specifies the classification, requirements, test methods, test rules, markings, packaging, transportation, and storage of pneumatic pinch valves. This standard applies to air-operated pinch valves with flange or internal thread connection. 2. Normative referencesThe following d Read More »
Air operated pinch valves are also known as pneumatic pinch valves and rubber sleeve valves. Because the valve core part uses a hose, its airtightness, corrosion resistance, and wear resistance are far superior to metal valves. Therefore, it is widely used in smelting, mining, electric power, chemic Read More »
