Fire Safe Seat High Performance Butterfly Valves PN10-100
High Pressure, High Temperature, Bi-directional, Zero Leakage Butterfly Valves
The SHENGFEI double offset fire safe seated high performance butterfly valve incorporates two seats which function together to seal off pipeline flow. In normal operation, the soft seat provides a bi-directional “bubble tight” shutoff (zero leakage)…

Features:
High Pressure, High Temperature, Bi-directional, Zero Leakage Butterfly Valves
The SHENGFEI double offset fire safe seated high performance butterfly valve incorporates two seats which function together to seal off pipeline flow. In normal operation, the soft seat provides a bi-directional “bubble tight” shutoff (zero leakage); the metal seat provides bi-directional shutoff in the event of a fire, in conformance to industry fire-safe requirements.The stem is one piece blowout-proof, Square end connect to operator. Rigorously 100% internal tests prove bi-directional zero leakage seal. Third-party inspections will be performed on the customer’s request.
