Dead End Service

For valves installed at the end of a pipe with no connection on one side, special designs such as threaded holes and bi-directional sealing are required to ensure proper functionality.

Easy Maintenance

The valve features a replaceable seat that can be easily accessed and replaced by loosening the seat retainer with specialized tools.

Fire Safe Seat

Our valve includes a dual-seal fire-safe design, with a primary soft PTFE seat and a secondary metal seat. In the event of a fire, the metal seat provides effective shut-off if the soft seat is compromised.
