This valve is mainly used for control of pipelines and other equipment on and off the medium,
applied to the rated working pressure 35,70,105 Mpa, path requirements for 52,65,78,103 mm,
working temperature is-29OC ~ 121OC, medium oil, gas and other non-acidic and acidic
environment, widely used wellhead equipment, well control equipment and various tube sinks.
the implementation of standard products: API SPEC 6A、SY5156-93
Working principle, structure and use instructions
1, the main valve by the valve body, valve seat, wave spring, gate, stem, valve cover,
seal packing, hand wheels and other parts form.
2, between the floating gate and the valve seat seal structure, and the gate and the seat sealing
surface spray high hardness abrasion, corrosion resistance alloys, automatic compensation
can be worn long life. Valve seal cavity filled with fat, enhanced seal performance and reduces
the friction coefficient.
3, with a balance bar gate at the bottom, sides with guide plates, valve stem seals on a back
seat, the valve to work under pressure of circumstances, can replace the valve stem seals.
4, valve cover seal packing with two Yx.
5, with two ball bearing in the thrust bearing, and are subject to open and close the load, and thus
open the torque is small, lightweight and flexible handwheel. 105Mpa manual valve to open
