The mud discharge valve, also known as the cover valve, is often used for discharging sludge at the bottom of the sedimentation tank of urban water plants and sewage treatment plants. The applicable medium for the mud discharge valve is the primary sewage. The temperature of the medium should generally be less than 50 ° C, and the working water depth is less than 10 meters. The mud valve is also used in the water treatment plant as a sludge and wastewater in the discharge tank. The mud valve is an angled structure with an internal nylon reinforced rubber diaphragm for long-term use of the mud valve.
JM744X hydraulic and JM644X pneumatic angle quick opening mud valve is an angular truncated valve made of hydraulic or pneumatic source. Usually installed in rows on the outer side wall of the bottom of the sedimentation tank to remove muddy sand and dirt deposited at the bottom of the tank. The valve is divided into two chambers by a nylon reinforced rubber diaphragm. The hydraulic or pneumatic source is connected, and the electric or manual two-position four-way reversing valve is used for quick mud discharge. The valve replaces the piston with a diaphragm, has no motion friction, and is more suitable for a granular medium such as mud, which greatly improves the service life of the valve.
