Overview
Product Introduction: The large-diameter pneumatic three control valves ZJHQ and ZJHX adopt a cylindrical thin-walled window shaped valve core guide, which is different from the liner guide of the plunger shaped valve core. Equipped with multiple spring actuators, it has the advantages of simple structure, light weight, small volume, and easy disassembly and assembly.
Product Details
Large caliber pneumatic three control valves ZJHQ, ZJHXpneumatic control valveAdopting a cylindrical thin-walled window shaped valve core guidance, different from the liner guidance of a plunger shaped valve core. Equipped with multiple spring actuators, it has the advantages of simple structure, light weight, small volume, and easy disassembly and assembly. Widely used for precise control of processes involving gases, liquids, and other media, such as maintaining pressure, flow rate, temperature, and liquid level at given values. Suitable for situations where a fluid is split into two streams through a three-way valve or two fluids are combined into one fluid through a three-way valve.
This series of products has two types: three-way merging and three-way branching. The nominal pressures are PN16, 40, and 64; The nominal diameter range is DN25-300. The applicable fluid temperature ranges from -60 ℃ to+450 ℃. The leakage standard is level IV. There are two types of flow characteristics: straight lines and parabolas.
