Non-Slam Check Valve- GMK- Prevents water hammer

Non Slam Check Valve

The use of non-slam check valves, which are particularly built for the conditions present here, is recommended. Because these valves do not slam when they shut, there is no sudden increase in pressure when they are used, as their name suggests. A non-slam check valve features an internal spring that works against the pressure of the opening fluid flow. This spring is located inside the disc of the check valve. When there is a significant enough flow of a medium, the spring will begin to compress, which will cause the valve to open. The spring will then begin to push the disc back toward the seating surface in the valve as the flow begins to decrease and eventually stops but before the flow direction changes

DESCRIPTION

The non-slam check valve is the most efficient way to get rid of the water hammer to install check valves that operate smoothly and silently on their own. Throughout both the opening and the ending, there was a profound quiet. Because the flow is stopped before the valve is turned around, there is no slamming sound. The seat’s conical form serves to both orient the body correctly and blocks out outside noise. In addition to the employment of non-slam check valves in applications such as these, the chemical processing industry, steam condensate systems, and the power generating sector also make use of these valves.

Benefits

Because the stroke length is shorter, the valve may be closed more quickly, resulting in a reduced amount of water hammer.
Incorporating a metal-to-metal seal into a system
Excellent dynamic performance with just a little decrease in pressure
The spring-loaded structure of the disc enables the installation process to be performed in any orientation.
Achieving a Closure in a Record Amount of Time Deflation Rates
It does not cause excessively High loss
