Silicone Rubber Lined Hard Back Valve Seat for Wafer Butterfly Valve
Basic Info
- Silicone rubber has excellent heat resistance, good corrosion resistance, elasticity and softness, high wear resistance and aging resistance, and is not easy to harden, become brittle or crack.
- High pressure resistance: The hard-backed valve seat is made of high-strength materials and can withstand high-pressure conditions, ensuring the reliability and safety of the valve.
- High wear resistance: The surface of the hard-backed valve seat is usually specially treated to have good wear resistance and can withstand the erosion of high-speed fluid and extend its service life.
- Easy maintenance: Since the hard-backed valve seat adopts a replaceable design, when the valve seat is worn or damaged, only the valve seat needs to be replaced instead of the entire valve, which facilitates maintenance and saves repair costs.
The Difference Between Soft-Back Seat and Hard-Back Seat
Soft-Back Seat
The entire material is composed only of rubber, so it is highly elastic and is also called a backless valve seat. Its installation method is more convenient for workers to repair, replace and disassemble later.
Hard-Back Seat
The material is composed of a hard back wrapped with rubber on the outside. The installation method is to use a professional valve assembly platform to press the valve seat into the valve body through a machine.
