Plug valve is a necessary part that is connected with high-pressure manifold in operation of cementing well and fracture in oil field and also suitable to gighpressure fluid control.
As plug valve assembling, the sealing surfaces were coated with high pressure grease made in USAand each valve was hydrostatic tested on strength and seal and no-leakage valve was permitted to provide to user.
It features compact structure, convenient maintenance, small torque, rapid open and simple operation, so it is the best valve in cementing/ fracture manifold.
Plug valve mainly consists of valve body, hand wheel, piston and etc.
1 material and working pressure:
forged of quality high strength alloy steel, are low torque
valves based on the technologies introduced from SPM. 1″,2″and 3″ plug valves with
rated working pressure of 6000,10000,15000 psi(42,70,105MPa) are available.
2 the working surrounding:
They can work in normal temperature, low temperature or H2S environments.The model of
plug valve available: SF42-1″×2″,SF70-1″×2″,SF105-1″×2″,SF42-2″×2″,SF70-2″×2″,SF100-2″
3 the type of end connection:
End connections of plug valves with sizes in English system may
be union or male/female thread (LP,TBG), and they can be freely connected with products
in international market.
4 the advantage for maintenance :
can be done without removal, and no special tools are needed for removal;
5 good sealing performance:
Visible: There is a visible positioner where we can see if valve is open or closed. Brake spring
will limit the position of valve. 3″hand wheel opener is suitable for opening in low temperature.
Valves can be opened freely and flexibly.
