HD7B42X/H Hydraulic large size air non return check valve

HD7B42X/H Large size hydraulic non return butterfly check valve is mainly applied in metallurgy, electricity, petroleum, chemical, air, Combustible gas, etc. This valve are often installed at the pump exit of non-corrosive fluids in the supplying & drainage systems. Similar to butterfly valve, the valve is used to prevent the medium backflow and reduce the water hammer pressure to protect the pipeline system.

Advantages of HD7B42X/H Hydraulic large size air non return check valve
1. Multi-functional;HD7Q42X/H,HD7Q43X/H butterfly valve series own the functions of gate valve and check valve;
2.Automatic constant slowly-closing; To avoid and reduce the backward flow & water hammer;
3. Small flow friction coefficient; The one of butterfly valve in large diameter is a little higher than gate valve.
4. Adjustable closing time; According to the pipeline system characteristics and clients' requirement, the closing time and switchover angle can be adjustable, which can eliminate or reduce the water hammer to protect.
