Our double-leaf check valve consists of a valve body, valve flap, valve stem and spring, and is connected by flange. Due to the short closing stroke of the valve flap and the spring loading, water hammer phenomenon can be significantly reduced. This valve is mainly applicable to water supply and drainage pipelines in cities, industries and high-rise buildings. Because of its shorter structure length compared to ordinary check valves, it is most suitable for places with installation space limitations.
● The structure length of the double-leaf butterfly check valve is short. Its structure length is only 1/4 to 1/8 of that of the traditional flanged check valve.
● It is small in size and light in weight. Its weight is only 1/4 to 1/20 of that of the traditional flange check valve.
● The valve disc of the double-leaf butterfly check valve closes quickly and the water hammer pressure is low.
● Horizontal pipe and vertical pipe can be used, easy to install;
● The double-leaf butterfly check valve has smooth flow and low fluid resistance.
● The operation is sensitive and the sealing performance is excellent;
● The valve disc of the double-leaf butterfly check valve has a short stroke and low impact force.
● The overall structure is simple and compact, with a beautiful design.
● Long service life and high reliability.
