FCNV系列针阀 Needle Valve, FCNV Series - 22,500 PSI

派克Autoclave的FCNV系列针型阀经过专门设计，可与22,500 psi（1,550 bar）的FCC锥形扩口连接。针阀可用于连接1/4“至1”外径的Parker高压釜管。Parker Autoclave's FCNV Series needle valve is specifically designed to interface with the FCC Flared Cone Connection to 22,500 psi (1,550 bar). The needle valves are available to connect with 1/4" to 1” O.D. Parker Autoclave tube sizes.

派克Autoclave的FCNV系列针型阀经过专门设计，可使用扩口圆锥连接（FCC）技术与油管接口。这项独特的正在申请专利的技术使用一个压缩套筒和一个扩口的管端来创建双密封连接，适用于高达22,500 PSI（1,550 bar）的各种中压应用。Parker Autoclave's FCNV Series needle valves are specifically designed to interface to tubing using Flared Cone Connection (FCC) technology. This unique patent-pending technology uses a single compression sleeve and a flared tube end to create a dual seal connection that is suitable for a wide range of medium pressure applications up to 22,500 PSI (1,550 bar).

这些阀可适用于1/4“，3/8”，9/16“，3/4”和1“ OD尺寸的管，并可选择五种阀体样式，包括2通直管和角管，以及三种方式配置。作为标准配置，所有阀门均由冷加工316不锈钢制成，并提供2507超级双工版本。316不锈钢版本的额定压力为20,000 PSI（1,379 bar），而2507 Super Duplex版本的额定压力为22,500 PSI（1,550 bar）。The valves are available to suit 1/4", 3/8”, 9/16”, 3/4" and 1” O.D. tube sizes, with a choice of five body patterns including 2-way straight and angle, and three 3-way configurations. As standard, all the valves are manufactured from cold worked 316 stainless steel, with 2507 super duplex versions available as options. The 316 stainless steel versions have a pressure rating of 20,000 PSI (1,379 bar), while the 2507 Super Duplex versions are rated at 22,500 PSI (1,550 bar).

作为标准，带PTFE填料的FCNV系列针型阀的工作温度范围为-18至232?C（0至450?F）。提供各种包装选项，可将下限扩展到-73?C（-100?F），将上限扩展到316?C（600?F）。As standard, FCNV series needle valves with PTFE packing have an operating temperature range of -18 to 232?C (0 to 450?F). Various packing options are available to extend the lower limit to -73?C (-100?F) and the upper limit to 316C (600F).

所有这些针形阀均具有不旋转的上升阀杆，以防止阀杆/阀座磨损，利用金属对金属阀座确保气密性关闭，并设有连接泄油孔以确保安全和检漏。All these needle valves feature a non-rotating rising stem to prevent stem/seat galling, utilise metal-to-metal seating to ensure bubble-tight shut-off, and incorporate connection weep holes for safety and leak detection.

FCNV系列针阀 Needle Valve, FCNV Series - 22,500 PSI

派克 Autoclave Engineers 中压针阀接口为 FCC 法兰连接可达 22,500 psi (1,550 bar).

派克's FCNV针阀设计服务于扩口法兰连接(FCC)技术.这种独特的新技术利用一个接头套筒和扩口管创建一个双重密封连接，适用于各种中压应用环境，压力可达 22,500 PSI(1,550 bar)。

阀门可连接1/4",3/8" 9/16" 3/4"and1" O.D.钢管尺寸，有五种阀体形式，包括两通直型及角型，还有三通形式。阀体材质均为 316 冷加工型不锈钢为标准材质，也可选择 2507 超级双相钢。316SS 不锈钢材质压力可达22,500 PSI(1,550 bar).

FCNV 系列阀门采用PTFE(聚四氟乙烯）填料为标准选项，温度范围为-18 到 232°C(0 到 450°F).多种材质填料选项可使温度低至-73°C(-100°F)，高可达316°C(600°F).

非旋转法官可预防阀杆/阀座磨损，利用金属对金属阀座确保气密性关闭，并将排水口连接更为安全，防止泄露。
