Seat adopts floating piston structure in order to enable theimport and outlet to realize bidirectional sealing and small switch working torque
Seat face of the soft seal valve insert PTFE to realize double seal, the seat face also acts as removing the dirt on the wedge disc
For the valve with metalto-metal seal, there is grease injector outside, grease gets into the sealing face through the injector and seat to realize the valve up to null leak
When fully opened, the valves channel is smooth and linear, with an extremely small flow resisting coefficient and no pressure loss, the pipeline can be cleaned with hair-ball through it
Using the packing structure with the ability of self-seal, it needs no constantly adjustment, features open and close lightly andseal reliably
An assisting sealing grease injection structure is set in thepacking to realize the valve up to null leak, it settling the problem for the packing place of universal valves to be easiest leak outward
Automatic removal of the high pressure in the internal cavity when the valve is about to close so as to ensure safety
Fully sealed structure leaves a good protective property, suitable for the requirement of 24-houe duty
Drive mode: Manual, pneumatic, electric, hydraulic, gearoperation
Structure: With flow guide hole, without flow guide hole
Used for the medium as petroleum, natural gas and more in oiltransportation pipeline, refinery, natural gas exploitation, gatherand delivery, petroleum exploitation, transportation and otherpipelines, as a device to flow and regulate medium in lines
