Slow-closing check valve, also known as the check valve, its role is to prevent the pipeline medium reverse flow. A valve that is opened or closed by the flow and force of a medium to prevent the flow of the medium back. The check valve belongs to the automatic valve class, mainly uses in the medium unidirectional flow pipeline, only allows the medium to flow in one direction, in order to prevent the accident. 300X slow-closing check valve is installed in the high-rise building water supply system and other water supply system at the pump outlet, to prevent media backflow, water hammer and water hammer phenomenon of the intelligent valve. The valve has the functions of electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of water supply system, and integrate the technical principle of slowly opening, quickly closing and slowly closing to eliminate water hammer, prevention of pump opening water hammer and pump stopping water hammer.
Characteristics of slow closing check valve - H300X:
1. DISC closed quickly, water hammer pressure is small.
2.Horizontal or vertical pipe can be used, easy to install.
3. Smooth flow passage, low fluid resistance.
4. Quick action and good sealing performance.
5. Disc travel is short, valve closure impact force is small.
6. Overall structure, simple and compact, beautiful shape.
7. Long service life and high reliability.
