The ZJHQ/ZJHX pneumatic diaphragm three-way regulating valve adopts a cylindrical thin-walled window-shaped valve core guide, which is different from the sleeve guide of the piston-shaped valve core. It is equipped with a multi-spring actuator and has the advantages of simple structure, light weight, small size, and convenient disassembly and assembly. It is widely used in processes for precisely controlling gases, liquids, etc., such as maintaining pressure, flow rate, temperature, and liquid level at given values. It is suitable for situations where one fluid is divided into two streams through a three-way valve or where two fluids are combined into one fluid through a three-way valve.
This series of products come in two types: three-way confluence and three-way diversion. The nominal pressure ranges from PN16 to PN64; the nominal diameter ranges from DN25 to DN300. The applicable fluid temperature ranges from -60℃ to +450℃. The leakage standard is level IV. The flow characteristics include linear and parabolic types.
