Easy Maintenance:
The valve seat is replaceable and can be easily removed by loosening the seat retainer with specialized tools, making maintenance quick and convenient.
Fire Safe Seat:
Designed for fire safety, the valve features a dual-seal system with a primary soft PTFE seat and a secondary metal seat. In the event of a fire, if the soft seat is damaged, the metal seat ensures effective shut-off.
