Performance and Characteristics
1. The working medium of the hydraulic cylinder of the bottom discharge valve of H742X hydraulic tank is used for clean water, and the pressure is taken from the pressure of tap water itself, without the need for additional equipment. 2. Matching electromagnetic directional valves with hydraulic cylinders facilitates automatic control, remote control, or centralized control.  

Working Principle
The bottom discharge valve of H742X pool is composed of a hydraulic cylinder and a valve body. Use a directional valve to change the fluid entering the upper and lower chambers of the hydraulic cylinder, pushing the piston to move and driving the valve plate to rise and fall, causing the valve to open or close to achieve fluid continuity.
