API Flanged Stainless Steel Swing Type Check Valve

Description
API flanged stainless steel swing check valve is installed on one-way flow pipelines. It is used to prevent reverse flow and leakage of medium, such as fluid, gas, etc. This stainless steel check valve is also applied to stop reversal of pump and driving motor.

Application
API flanged stainless steel swing check valve is widely applied in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and other pipeline systems.

Features
1. Two times shot blasting processing of valve surface make the valve look fine and smooth.
2. Disc of API flanged stainless steel swing check valve is with high strength and stiffness.
3. CNC processing technology is adopted to produce disc.
4. High intensity and flexibility of rocker are beneficial to close disc.
5. The disc sealing surface can be customized.
6. Small friction between sealing surfaces ensures low wear rate of check valve.
7. Our stainless steel check valves have passed API6D and CE certification.

Working Principle
API flanged stainless steel swing check valve opens and closes automatically depending on force from media flowing. It allows medium to flow through it in only one direction, and prevents reverse direction flow. Disc will open under the pressure of forward flow fluid. When fluid flows in reverse direction, the disc will be closed by fluid pressure and dead weight so as to cut off the flow.

Payment, Package, Transportation & Warranty
1. Products can be paid by T/T, D/P, D/A, L/C, and so on.
2. Standard exporting wooden cases are employed for packaging.
3. Items are transported by air, sea or railway.
