These valves are used in the inspection and repair of pneumatic valves for faucets, fire hydrants, and more.
They can be used in sliding parts such as valves and pumps.

Faucet Valve Seat
Features
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.
Structure
Fluororesin (PTFE) is firmly adhered to the sliding rubber part which comes in contact with the valve body.Performance
Evaluation of frictional resistance
PTFE 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) | |
PTFE | 0.05 | 0.02 |
NBR | 1.0~1.5 | 0.5~0.8 |
Based on AWM test results
Evaluation of adhesive strength
Special 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) | |
Peel strength | 7N/mm | 7N/mm |
Destruction state | No rubber breakage/PTFE rupture | 100% destruction of rubber part |
Conforms to JIS K6256 180-degree peel test
