Product overview
Simple structure, excellent universal interchangeability, and low cost. The valve stem seal is resistant to deformation, effectively preventing leakage, with overall superior support performance, ensuring stability and durability. Minimal use of rubber in the valve seat reduces potential expansion effects, making it easier to control torque within an appropriate range. The valve seat sealing surface and backing are integrated, minimizing deformation and offering high strength.

1. Simple structure, good general interchangeability, low price.
2. The valve stem seal is not easy to deform so as to avoid the valve stem leakage phenomenon, the overall support performance is good, stable and firm.
3. The amount of seat rubber is small, the potential impact of expansion is small, easy to control the torque in the appropriate range.
4. The sealing surface of the valve seat and the backrest are integrated, which reduces the deformation of the valve seat and has high strength. -
