【Product Applications】

The H41H and H41Y lift check valve series are suitable for water, steam, gas, corrosive media, food, oil, pharmaceuticals, etc.

【Product Features】

1. The valve disc stroke is only 1/3 of the valve disc diameter, greatly reducing the valve disc closing time and effectively reducing water hammer pressure in lift check valves.

2. The sealing surface is made of alloy steel or hard alloy, and the sealing pair materials are reasonably matched, resulting in a long service life.
