Bulkhead (gate/block) valves: Pressure class: PN6.4~42MPa, Class300~2500. Nominal size: DN225~1000, 10"~40"
Design and manufacturing standards: JB/T3595, ASME B16.34. Materials: WCB, WC6, WC9, C12A, F91, F92
Structural features: pressure self-sealing structure with flat O-ring; the seat sealing face is overlaid with stainless steel. The middle cavity uses a stainless steel wire mesh-reinforced
flexible graphite seal, allowing repeated hydrostatic tests; the bulkhead seal is achieved by preloading the bulkhead plate with adjusting screws.
