Products Name:D43H Flange Butterfly Valve
Liquid-controlled butterfly valve is a butterfly valve, liquid-controlled butterfly valve sub-pressure-type, lock-type and energy-saving three. It applies to the pump outlet and turbine inlet piping, as a closed-circuit and check valve, used to avoid and reduce the piping system in the media backflow and excessive water hammer to protect the piping system.
Product Usage
D43H flange butterfly valve is suitable for food, beverage, medicine, chemical and other pure pipelines and industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines for opening and closing or regulating medium flow.
Detailed description
D43H flange butterfly valve features:
