JM744X/JM644X Diaphragm type hydraulic pneumatic quick opening sludge discharge valveDetailed product description：

The main feature of the JM744X/JM644X diaphragm hydraulic and pneumatic quick opening mud discharge valve is the use of a dual chamber diaphragm transmission mechanism instead of a piston type, which has no motion wear and has a long service life. The main purpose is to install it outside the bottom wall of various sedimentation tanks to remove sediment and dirt from the bottom of the tank.

Characteristics
1. The JM744X/JM644X diaphragm hydraulic and pneumatic quick opening mud discharge valve adopts a fully lined rubber valve plate, with good sealing effect and no leakage. Durable and long-lasting.  
2. Install a throttling device on the diaphragm pressure plate of the double chamber diaphragm to perform the functions of opening, closing, and opening.  
3. Adopting a dual chamber diaphragm transmission mechanism, the valve opens smoothly and quickly, with the following advantages over piston valves: a. No motion wear; b. Not sensitive to sedimentation; c. No lubrication required, no mechanical wear, no regular replacement of rubber products, long service life;  
4. The driving medium pressure water can be directly supplied with tap water or clean water from the upper part of this water tank (pressure ≥ 0.05MPa), which is easy to operate.
5. High degree of automation, capable of achieving remote automatic control and centralized control.
