Expanding Gate Flat Gate Valve Forged Steel API6D Gear Operated Gate Valve 4 Inch DN100 900LB Through Conduit Gate Valve
Infomation
Flat gate valve widely used in oil, natural gas long-distance pipelines and gas fields Valves used in forging or casting body, the gate designed with diversion holes, non-diversion holes; single discand double disc structure; Seat used bi-direction seal seat which mainly based on the metal seat sealing and assisted with soft seat sealing as a second type of seal. The series of parallel type gate valve has rational design, compact structure, sulfur resistance, corrosion resistance, wear-resistant, reliable sealing, and light torque of switches, easy-to-use.

Design Features
Block and Bleed Capability
When in the closed position the Calvary valve forms a tight seal on both seats, allowing the valve body to be drained. For specific application please consult factory.
Tight Mechanical Seal
Both upsteam and downstream are blocked off simultaneously. This me-chanical advantage is normally undisturbed by pressure gradient fluctua-tions or vibrational reflux. The seal is both TFE-to-metal and metal-to-metal.
Smooth, continuous conduit
Virtual elimination of turbulence. Pressure gradient through valve stays the same, relative to the pressure drop in an equal-length pipe.
Seat Face Protection
Seat life is greatly extended by engineering the seats to face outwards in order to avoid contact with the flow medium and engage fully with the gate. This protection is in both the fully open and fully closed positions.
Gate Centralizer
Valve diameters that are 6 inch or larger feature the leverlock gate central-izer, which retains the gate- segment assembly in a neutral position during opening and closing travel. However expansion of the assembly for seating, in an open or closed position, is permitted.
Actuation
The VERVO 6D gate valve is furnished with either hand wheel or bevel gear operators, but they can readily be adapted to fit a wide range of power operators if desired. Power operators can be installed in the field or at the manufacturing facility.
Thermal Relief Options
The split gate design allows for excess body pressure to develop in the body cavities of closed valves, and usu-ally results from heating in the valves in liquid service. A thermal body cavity relief system can be provided to relieve the excess body pressure upon request.
