Parker Hi-Check series of non-return valves - 派克止回止回阀 (10,000 PSI) – HI 止回阀系列
派克止回阀 (10,000 PSI) - Hi Check 系列

派克的高性能止回阀可为用户提供高达 10,000 psi/689 bar 的冷工作压力额定值，最大开启压力为 10 psi。Parker 的 Hi Check 系列高性能止回阀设计用于过程仪表应用中流体和气体的单向流动控制。有两种单向阀型号可供选择，冷工作压力为 10000 PSI (689 bar) 和 6000 PSI (414 bar)。两个止回阀的开启（或“开启”）压力均为 10 PSI (0.7 bar)。这些坚固的止回阀采用两件式金属阀座设计，可最大限度地减少泄漏风险。Parker 止回阀可选择一体式外螺纹或内螺纹 NPT，或单或双套圈压缩式端部，压缩端使用户无需使用锥形螺纹和螺纹密封剂 - 进一步减少潜在泄漏的数量路径并避免系统污染问题。

入口和出口连接范围广泛，包括 1/4"、3/8" 和 1/2" 的英制尺寸，以及 6 mm、10 mm 和 12 mm 的公制尺寸。止回阀旨在满足 ANSI/ASME B.16.34 的压力和温度要求，但受阀座材料的限制。可提供符合 NACE 的版本。

Parker's high performance non-return valves can offer the user a cold working pressure rating up to 10,000 psi/689 bar maximum, with a cracking pressure of 10 psi maximum. Parker's Hi Check series high performance non-return valves are designed for unidirectional flow control of fluids and gases in process instrumentation applications. There is a choice of two check valve models, with cold working pressures of 10000 PSI (689 bar) and 6000 PSI (414 bar). Both check valves have an opening (or ‘cracking') pressure of 10 PSI (0.7 bar). These robust check valves feature a two-piece metal seated body design to minimise any risk of leakage. The Parker check valves are available with a choice of integral male or female NPT, or single- or two-ferrule compression style ends, the compression ends enable users to eliminate the use of taper threads and thread sealant – further reducing the number of potential leakage paths and avoiding system contamination problems. There is a comprehensive range of inlet and outlet connections, covering imperial sizes of 1/4", 3/8” and 1/2", and metric sizes of 6 mm, 10 mm and 12 mm. The check valves are designed to meet the pressure and temperature requirements of ANSI/ASME B.16.34, as limited by the seat materials. NACE compliant versions are available. As standard, Hi Check valves are manufactured from 316 stainless steel, with duplex and monel versions optionally available. For maximum applications flexibility, there is an extensive choice of O-ring materials, including FPM75 and V1238-95 fluorocarbon rubber, Buna-N, ethylene propylene rubber and highly fluorinated fluorocarbon rubber.
