Overview

The G300X slow closing check valve is a high-performance control valve independently developed and manufactured by our factory based on the introduction of advanced technology from Europe and America, combined with domestic working conditions. It integrates the functions of electric valve, check valve, and water hammer eliminator, and can effectively achieve integrated automatic control of pump unit opening, slow closing, and check. This valve can effectively eliminate the water hammer hazard caused by medium backflow and rapid changes in flow rate during pump shutdown, protecting the safety of the pump and pipeline system. The valve adopts a unique dual chamber and pilot valve control system, which achieves smooth and impact free closure by adjusting the slow closing time and angle. It is particularly suitable for water pump outlet pipelines in high-rise buildings, industrial and mining enterprises, municipal water supply and fire protection systems. This valve has the advantages of low flow resistance, reliable operation, easy maintenance, and significant anti backflow and water hammer elimination effects. It is a key equipment to ensure the safe and stable operation of long-distance and high head water conveyance systems. Welcome to consult and purchase.

feature

The working principle of G300X slow closing check valve is to use the pressure and flow rate changes of the medium itself in the pipeline as the control power, and achieve automatic and phased closure of the valve disc through a pilot control system. When the water pump is running normally, the medium pressure pushes the valve disc to fully open; At the moment when the water pump suddenly stops, the valve disc begins to quickly close to about 80% -90% opening under the action of medium reflux and spring. At this time, the valve enters the preset slow closing stage. By accurately controlling the closing speed of the remaining opening through an independent regulating valve, the medium slowly flows back, effectively eliminating the destructive water hammer pressure caused by sudden flow rate changes and achieving smooth protection of the water pump and pipeline system.
