[ ANA ] 1177 Brass Swing Check Valve One-way Reverse Flow Non-return (1/2")

Descriptions

• One-way flow control--it relies on the pressure of the medium to produce an effect that prevents the backflow of the medium. Only allow media to flow in one direction to prevent moderate backflow. 
• Explosion-proof and wear-resistant--The valve body is characterized by pressure, explosion resistance and durability... uniform wall thickness, high wear resistance and long service life. 
• Exquisite craftsmanship - the inner wall of the brass check valve is polished, the surface is smooth, no scaling, no clogging, practical and durable.
• Wide range of uses--Most piping systems come in a variety of sizes. Widely used in chemical, construction, petroleum, light and heavy industry, fire protection, power, aerospace, shipbuilding...

Principle Of Check Valve

When the fluid in the forward movement process, the valve flap by the fluid pressure will be pushed open, the fluid will be smooth through the pipeline into the next process. However, when the fluid flows in the reverse direction, the valve flap and the The valve seat closely fits, preventing the reverse flow of the medium and leakage.

Check Valve Workflow

When the check valve is in normal working condition, the valve flap is in the open state, and the fluid can flow through unhindered. When the fluid flows in the reverse direction, the valve flap closes quickly, avoiding the backflow of fluid and preventing the leakage of the medium in the pipeline, which ensures the safety and stability of the pipeline to the environment.
