Soft Seat In-Line Check Valves (5000 psi) One Piece Body, Female Fitting Ends - CPIFF


派克单向阀是单向流动的控制装置, 主要用于液压系统, 以防止由于液流的背压而造成的损害。 凭借软密封（几乎零泄露）引导的提升阀设计和4:1的安全系数，CPIFF系列单向阀非常适用于允许一个方向自由流动但反方向不能流动的应用场合。这些简化的软密封提升阀对流动产生的限制最小，并可实现反向截流，多种开启压力和密封件可选，可兼容大部分流体。CPIFF 系列单向阀 (5,000 psi / 350 bar) 是软阀座、无泄漏座阀型单向阀, 采用紧凑的单片阀体结构, 标准的开启压力为 5, 15, 25 及 65 psi (0.35, 1.05, 1.75 及 4.55 bar)。可供货的规格范围很广, 可大至 1""。带内螺纹接头油口, 通流能力至 30 gpm (113 lpm)。

单向阀是流体系统的重要元件, 但在系统建立时却常常被忽视。单向阀可通过以下方式优化系统的性能:
- 促使液流只在一个方向上流动
- 减少由背压引起的损坏隐患
- 隔离系统的分支或系统元件

基本的单向阀由带有进、出油口的阀体和由弹簧压力控制的内部可移动座阀芯组成。大多数情况下单向阀是常闭的, 当液流的压力高于弹簧所产生的背压 (开启压力) 时, 单向阀开启, 允许液流只在一个方向上流动。当反向液流试图流进出口时, 阀芯关闭, 阻止反向流动。

软阀座单向阀在阀芯和阀体之间带有一个 O 型圈或类似的弹性密封结构, 从而改善了防泄漏的性能。 这种软阀座设计与 "清洁" 系统相容, 但对存在大流量冲击的系统不适用。其密封材料决定了阀的使用温度范围。

CPIFF Series Check Valves (5,000 psi) are soft seat, zero leakage poppet check valves with compact one piece construction. Standard crack pressures are 5, 15, 25, and 65 psi. These valves are available in a wide range of sizes up to 1"", with female fitting ends and flow capacities up to 30 gpm.

Check valves are important components that are often overlooked when building a fluid system. A check valve can optimize system performance in the following ways:
- Ensure hydraulic fluid flows in only one direction
- Eliminate potential damage from back pressure
- Isolate sections of a system or system components

Basic check valve construction consists of a valve body with an inlet and an outlet port. Inside, a moveable poppet valve is controlled by spring pressure. In most cases the valve is normally closed, opening when the fluid pressure is greater than the spring force (crack pressure), thus allowing the fluid to flow in only one direction. When reverse flow attempts to enter though the outlet the poppet closes and flow through the valve is stopped.

Soft seat check valves have an O-ring or similar elastomeric seal between the poppet and body for improved leak resistance. The soft seat design is most compatible with ""clean” systems and is not indented for use in systems that have high surge flow. The seal material dictates the temperature range of the valve.

Technical Characteristics:
- Sizes: 1/4” to 1”
- Materials: Steel, Brass
- Seal Material: Fluorocarbon
- Standard Crack Pressures (psi): 5, 15, 25, and 65
