Three biased multi-level metals hard seal butterfly valve series,is the long life which the our company newly develops,the energy conservation butterfly valve.
The valve is a kind of energy saving valve, generally installed in the bottom valve of the water pump suction pipe to limit the return of liquid water in the water pump pipe, mainly used in the pumping line.
The opening and closing part of the hard sealed gate valve is the gate plate, whose motion direction is perpendicular to the fluid direction. The gate valve can only be fully opened and closed without adjustment or throttling.
Silent check valve is to rely on the flow of the medium itself and automatically open, close the disc, used to prevent media backflow valve, also known as check valve, one-way valve, silent check valve backflow valve, and back pressure valve.
H71H(W) Check valve consists of valve body, disc, spring, etc. It is installed horizontally or vertically in the pipeline system to prevent media backflow. It has short structure, small volume and light weight.Fast disc closing, low water hammer pressure;The flow passage is unobstructed and the fluid resistance is small;Sensitive action, good seali1
