      ZJHP Pneumatic Diaphragm With Hand Wheel Single-seat Regulating Valve product details

      ZJHP Pneumatic Diaphragm With Hand Wheel Single-seat Regulating Valve Product description:

      The ZJHP Pneumatic Diaphragm With Hand Wheel Single-seat Regulating Valve produced and sold by Baigang Valve Group adopts top guide structure and multi-spring actuators.It has the advantages of compact structure, light weight, sensitive action, S-streamline fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc.Widely used to accurately control gas, liquid and other media, process parameters such as pressure, flow, temperature, liquid level to maintain a given value.Especially suitable for small leakage valve before and after the pressure difference is not big working occasions.

      This series of products have a standard type, regulation cut off, bellows sealed, jacket insulation and other varieties. Nominal product pressure rating PN10,16,40,64; body diameter range DN20 ~ 200. For fluid temperature from -200 ℃ ~ + 560 ℃ range of a variety of grades. Leakage standards have grade IV or VI level. Flow characteristics are linear or equal percentage. A wide variety of specifications to choose from.


      ZJHP Pneumatic Diaphragm With Hand Wheel Single-seat Regulating Valve Features:

       1, top-oriented single-seat control valve, compact structure, fewer parts, easy maintenance. 
       2, the metal spool for a variety of workplaces, up to Level IV leakage standards, ZXPQ-type soft-sealed spool up to Level VI leakage standards. 
       3, the valve body designed by the principle of fluid mechanics, such as cross-section low flow resistance flow channel, the rated flow coefficient increased by 30%. 
       4, adjustable range, the inherent adjustable ratio of 50. 
       5, the implementing agencies using multi-spring structure, a 30% reduction in height, weight reduction of 30%. 
       6, ZXPV bellows sealed control valve, the valve stem to form a complete seal, blocking fluid leakage. 
       7, ZXPJ-type control valve with a thermal jacket for fluid cooling easy to crystallize, clogging caused by solidification of the occasion.
