The bottom end of the suspension angle check valve is connected to the single well pipeline and the other end to the flow line. After drilling due to the impact of liquid, steel ball suspension, liquid from one side into the process. When the well is shut down, the steel ball falls into the ball seat, enters the check seal state, prevents the crude oil reverse flow.

Main features:

1, the valve body adopts the full-channel structure, with the advantages of large flow rate and low resistance.

2, for industrial sewerage networks with high viscosity and suspended solids

3, the overall structure, simple and compact, reasonable design.

4, long service life, high reliability.
