Product Description Application · Complying with GB, ANSI and other standards· Control valves applied to occasions where there is no external energy on site, the control accuracy is not high, and automatic pressure stabilization control is required· Nominal diameter: DN15 ~ DN150, NPS 1/2" ~ 6"· Nominal pressure: PN16, ASME CL150· Medium temperature: -40° C ~ +80° CFeatures · Various valve body materials for selection, such as cast steel, cast stainless steel, low-temperature and high-alloy steel or special materials· Pressure setting on the controller supported, which is convenient, quick and labor-saving, and allows continuous setting in running state· Improved control accuracy, being about twice as accurate as that of ZZY self-operated type· Highly sensitive, being capable of sensing very small pressure changes· Large pressure reducing ratio, for example the differential pressure ratio reaches 1600 (0.8MPa before the valve and 50mmH20 behind the valve)· Often adopted for the nitrogen sealing system of storage tanks to adjust the pressure of nitrogen in the tankTechnical SpecificationsNominal diameter DN (mm)15/20253240506580100125150Diameter of valve seat D (mm)61520253240506580100125150Rated flow coefficient (Kv)0.3245812.520325080125160320Range of pressure adjustment (kPa)Selection in the range of 0.5 - 100Nominal pressure PN (MPa)1.0 1.6Medium temperature (°c)-40-80Flow characteristicsQuick openingAdjustment error (%)< 5Allowable pressure drop (MPa)1.61.61.10.60.4Effective area of actuator diaphragm (cm2)200280400Allowable leakage quantityHard valve element: Class IV (10-4XKv), Soft valve element:Class VI (GB/T4213-2008), basically no leakage Packaging & DeliveryCategoryInternational Commercial Terms (Incoterms)Terms of PaymentNearest PortZZYP-16II Pilot-Operated Pressure RegulatorCIF, CFR, DAPLC, T/T, D/PShanghai, Guangzhou, TianjinRelated ProductsZZYP Pressure RegulatorZZCP/ZZVP Differencial Pressure/Micro-Pressure RegulatorA100 Globe Control ValveA400 Ball ValveA700Butterfly ValveCompany Profile
