Product Description
H44H-40C Flanged Swing Check Valve refers to a valve whose opening and closing parts are circular discs and act by its own weight and medium pressure to block the backflow of the medium. It is an automatic valve, also known as a check valve, a one-way valve, a return valve or an isolation valve.
The movement mode of the valve disc is divided into lift type and swing type. The lift check valve is similar in structure to the globe valve, except that it lacks the valve stem that drives the valve disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened.
Conversely, the valve H44H-40C is closed when the medium flows back.
The swing check valve has a disc that is inclined and can rotate around the axis, and the working principle is similar to that of the lift check valve. The check valve is often used as the bottom valve of the pumping device, which can prevent the backflow of water. The check valve is used in combination with the globe valve, which can play the role of safety isolation.
Main features
1.The middle port of the valve adopts a pressure self-tightening sealing structure. The higher the medium pressure, the better the sealing performance;
2.The sealing surface is made of surfacing stellite cobalt-based cemented carbide, which has high hardness, corrosion resistance, cavitation resistance, excellent anti-scratch performance, and long service life of the valve;
3.The H44H-16CFlanged Swing Check Valveis a straight-through type, and the medium flow resistance is small;
4.The opening and closing of the valve is realized by the force of the medium, and it is automatically and quickly closed when the medium returns;
5.Maintenance and repair are convenient and fast.
