Parker派克Snap-tite CPIFF Series內聯單向閥
Soft Seat In-Line Check Valves (5000 psi) One Piece Body, Female Fitting Ends - CPIFF


派克單向閥是單向流動的控制裝置, 主要用于液壓系統, 以防止由于液流的背壓而造成的損害。 憑借軟密封（幾乎零泄露）引導的提升閥設計和4:1的安全系數，CPIFF系列單向閥非常適用于允許一個方向自由流動但反方向不能流動的應用場合。這些簡化的軟密封提升閥對流動產生的限制最小，并可實現反向截流，多種開啟壓力和密封件可選，可兼容大部分流體。CPIFF 系列單向閥 (5,000 psi / 350 bar) 是軟閥座、無泄漏座閥型單向閥, 采用緊湊的單片閥體結構, 標準的開啟壓力為 5, 15, 25 及 65 psi (0.35, 1.05, 1.75 及 4.55 bar)。可供貨的規格范圍很廣, 可大至 1""。帶內螺紋接頭油口, 通流能力至 30 gpm (113 lpm)。

單向閥是流體系統的重要元件, 但在系統建立時卻常常被忽視。單向閥可通過以下方式優化系統的性能:
- 促使液流只在一個方向上流動
- 減少由背壓引起的損壞隱患
- 隔離系統的分支或系統元件

基本的單向閥由帶有進、出油口的閥體和由彈簧壓力控制的內部可移動座閥芯組成。大多數情況下單向閥是常閉的, 當液流的壓力高于彈簧所產生的背壓 (開啟壓力) 時, 單向閥開啟, 允許液流只在一個方向上流動。當反向液流試圖流進出口時, 閥芯關閉, 阻止反向流動。

軟閥座單向閥在閥芯和閥體之間帶有一個 O 型圈或類似的彈性密封結構, 從而改善了防泄漏的性能。 這種軟閥座設計與 "清潔" 系統相容, 但對存在大流量沖擊的系統不適用。其密封材料決定了閥的使用溫度范圍。

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
