Dead End Service

For valves installed at the end of a pipeline where one side has no connection to a pipe or flange, special design features such as threaded holes and bi-directional sealing are required.

Easy Maintenance

The valve features a replaceable seat that can be easily serviced. Simply loosen the seat retainer using specialized tools to disassemble and replace the seat.

Fire Safe Seat

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