The sleeve of the hose valve is the core component that determines the performance, durability and efficiency of the pinch valve. Hefei Huayun has a unique chemical formula developed independently and uses high-quality synthetic rubber to produce the sleeve. The rubber is reinforced with multiple layers of woven materials and is processed with high precision. Therefore, the sleeve can be fully compressed and no leakage will occur. Other types of valves are easily damaged by abrasive materials. The pinch valves and sleeve produced by Hefei Huayun can solve such difficult and complicated problems.
Huayun has its own sleeve manufacturing technology and capabilities, so it has more advantages in quality and cost control. While meeting its own pinch valve needs, it can also specially customize replacement sleeves for all other domestic and foreign pinch valve brands.

The sleeve is the core component of the pinch valve. The sleeve independently developed by Hefei Huayun is produced using the international standard structural winding method. It is composed of surface rubber, reinforcement layer, and outer layer rubber. The operating pressure can reach 2.5Mpa and has a long service life.
