J744X hydraulic angle type sludge discharge valve adopts electric two-position four-way reversing valve or manual two-position four-way or one-way valve for centralized control, which is easy to operate and flexible to open and close.  This valve is mainly installed outside the bottom wall of the various sedimentation tanks to remove the sediment and dirt at the bottom of the tank.  Related products include J644X pneumatic quick opening angle type, JM744, JM644X pneumatic, hydraulic quick opening type, H742X hydraulic type, 100S angle diaphragm type.

    Working principle 　　
The hydraulic sludge discharge valve is composed of a hydraulic cylinder and an angle stop valve. The hydraulic angle sludge discharge valve hydraulic cylinder drives the valve plate up and down to open or close the valve body channel to achieve fluid flow.  The L-shaped leather cup of the hydraulic cylinder piston seal has good sealing performance and is durable.  The leather bowl is made of absorbent leather.

    The J744X hydraulic angle type mud discharge valve has a fast opening speed. Generally, the valve plate is fully opened within 15 seconds, and the valve plate and the valve body are softly sealed. After closing, the sealing performance is good and there is no leakage, so that it can be repaired and replaced.  The reversing valve controls the hydraulic cylinder, which can realize remote control and automatic control.  If equipped with a manual device, 4-12 units can be installed in a row at the same time to start and close. The driving pressure is taken from the water plant itself, without additional equipment, which can save manpower, material resources and energy.
