Faucet Valve Seat
They can be used in sliding parts such as valves and pumps.
The sliding part of the valve seat is covered with fluororesin (PTFE), which has the following advantages:
- Prevents sticking to the valve body
- Provides excellent abrasion resistance
- Reduces friction resistance
- Reduces permanent strain and stabilizes the seal due to the rubber elasticity
- Prevents deformation and elongation with reinforced brackets
It conforms to Japan Water Works Standard JWWA B-126 and is also hygienically safe.
StructureFluororesin (PTFE) is firmly adhered to the sliding rubber part which comes in contact with the valve body.
Evaluation of frictional resistancePTFE has very low static and dynamic frictional resistance and has approximately 1/30th the resistance of general rubber.
|Static frictional resistance (unit: N)||Dynamic frictional resistance (unit: N)|
Based on AWM test results
Evaluation of adhesive strengthSpecial adhesive technology is used to provide adhesive strength that leads to rubber breaking without separating at the interfacial boundary.
|Nitrile rubber (NBR)||Chloroprene rubber (CR)|
|Destruction state||No rubber breakage/PTFE rupture||100% destruction of rubber part|
