The crucial part of every pinch valve is the sleeve.
The better the quality of the pinch valve sleeve, the longer the service times of the pinch valve and the sleeve. If the pinch valve sleeves are in service for a long time, this helps to maintain extremely low maintenance costs for every system. A simple change of the pinch valve sleeves can be carried out by the customer on site with the aid of the detailed fitting instructions, which is crucial to keeping very short production downtimes.
The pinch valve sleeves are manufactured in various forms for air operated or mechanically actuated pinch valve and according to the body's design or construction type.
The sleeve for the air operated or mechanically actuated pinch valve is produced using various manufacturing procedures. Different manual winding procedures, conventional injection processes or manual packaging in moulds are all manufacturing procedures employed for pinch valve sleeves.The structure of each pinch valve sleeve decides the cycle frequency involved, as well as the closing and opening characteristics.
The pinch valve sleeves come in different elastomer qualities. Therefore, various lasting properties, areas of application and operating temperatures are possible. The quality of the elastomer is crucial to the life time and anti-abrasion characteristics of the pinch valve sleeves.
The differential pressures of the air operated pinch valve sleeves can be affected by the different Shore hardness levels of elastomers. Optimally designed sleeve controls for air operated pinch valve contribute to their long lifetime. The setting of the optimal differential/control pressure, which is needed for actuating the air operated pinch valves sleeve, is also of enormous importance to the sleeve's lifetime.
