FA49H wave explosion-proof safety valve, is a shock wave that is able to eliminate water hammer, water hammer shock can stop the water with a safety valve. It is composed of multiple sets of valve products, the function played by a single valve can not be achieved. The valve installed at the head of water projects in the pipeline to block the way waves and combined wave and prevent water hammer shock wave along the pipeline within the first water supply into the system to achieve the elimination of destructive water hammer shock waves to the protection system of its facilities, operation and security policy purposes. The main valve part material as follows: 

 Part Name Material 
 Stainless steel body 
 Stainless steel valve cover 
 Stainless steel + nitrile rubber piston
