Product Description:<\/strong>
\nThe new series of pneumatic membrane pass-through single-seat control valves of ZXP adopts a top guide structure and is equipped with a multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, S-streamlined fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, and easy disassembly and assembly. It is widely used in precise control of gases, liquids and other media, and process parameters such as pressure, flow, temperature, and liquid level are kept at a given value. It is especially suitable for working occasions where the pressure difference between the front and rear of the allowable leakage valve is not large.
\nThis series of products has a variety of varieties such as standard type, adjustable cutting type, bellows sealing type, jacket insulation type, etc. The nominal pressure grades of the product are PN10, 16, 40, 64, and the valve body diameter range DN20~200. Applicable fluid temperature ranges from -200\u00b0C~560\u00b0C. The leakage standard is class IV or level VI. The flow characteristics are linear or equal percentage. A wide variety of varieties and specifications are available.<\/p>\n

Product Features:<\/strong>
\n1. Top guide single-seat control valve, compact structure, few parts, easy maintenance.
\n2. The metal valve spool is suitable for a variety of working occasions, reaching the level IV leakage standard, and the ZXPQ type soft seal structure valve core reaches the level VI leakage standard.
\n3. The valve body is designed as an equal-section low-flow resistance channel according to the principle of fluid mechanics, and the rated flow coefficient is increased by 30%.
\n4. The adjustable range is large, and the intrinsic adjustable ratio is 50.
\n5. The actuator adopts multi-spring structure, which reduces the height by 30% and the weight by 30%.
\n6. ZXPV bellows sealed control valve forms a complete seal on the moving valve stem to block fluid leakage.
\n7. ZXPJ type control valve with insulation jacket, which is used when the fluid is easy to crystallize and solidify after cooling, causing blockage.<\/p>\n
