Coliter ® Quick Opening Mud Valve – PN0.6~1.0, 0~80°C, Diaphragm-Actuated Sludge Discharge for Sedimentation Tanks

JM744X Quick Opening Mud Valve – Angle-Type Hydraulic/Pneumatic Sludge Valve with Nylon-Reinforced Rubber Diaphragm for Clog-Free Blowdown

The Coliter® JM744X Quick Opening Mud Valve is a specialized angle-type sludge discharge valve designed for rapid and reliable removal of sediment, sludge, and debris from the bottom of sedimentation tanks, clarifiers, reservoirs, and wastewater treatment basins. Typically installed in rows along the tank’s outer wall, it features a robust diaphragm-actuated mechanism that replaces traditional pistons—eliminating moving friction parts and significantly enhancing durability in abrasive granular media like mud. The valve body is divided into two chambers by a nylon-reinforced rubber diaphragm; when connected to a hydraulic or pneumatic source and controlled via a 2-position 4-way directional valve (electric or manual), it enables instantaneous full-port opening for high-capacity blowdown. Constructed from cast iron, ductile iron, or carbon steel, with ductile iron or bronze valve disc, stainless steel valve rod and spring, and an A3 steel bonnet, it ensures long service life under harsh conditions. Rated for PN0.6 or PN1.0 (0.6–1.0 MPa), it operates within a temperature range of 0℃ to 80℃ and is suitable for water and sewage. Available in sizes from DN80 to DN400, with flanged ends per GB/T 17241.6 / GB/T 9113, and tested to GB/T 13927 / API 598. Its full-port, straight-through flow path prevents clogging, while the quick-opening action minimizes downtime—making the JM744X ideal for municipal water treatment, industrial wastewater plants, and fire water tank maintenance.
