雙單向節(jié)流閥， Z2FS22
產(chǎn)品概述
雙單向節(jié)流閥Z2FS22是一種疊加式設計的液壓控制閥，主要用于限制液壓系統(tǒng)中一個或兩個工作油口的主流量或先導油流量。該閥通過調(diào)節(jié)節(jié)流口截面積實現(xiàn)流量控制，反向時油液通過單向閥自由回流，確保系統(tǒng)穩(wěn)定性和效率。其設計適用于垂直疊加裝配，可靈活選擇進口或出口節(jié)流模式，滿足不同工況需求。通徑為22mm，工作壓力可達31.5MPa，流量范圍至360L/min，廣泛應用于工程機械、冶金設備等領域。412
結構特點
Z2FS22采用對稱布置的雙單向節(jié)流閥結構，包含閥體、節(jié)流螺栓、調(diào)節(jié)螺釘、O形圈等組件。通過軸向調(diào)節(jié)節(jié)流閥芯改變節(jié)流口大小，實現(xiàn)精確流量控制；反向流動時，彈簧推動閥芯使油液經(jīng)單向閥無阻礙通過。閥體材質(zhì)為碳鋼，密封件兼容礦物油和磷酸酯液壓油，工作溫度范圍為-20℃至+80℃。其緊湊的疊加式設計便于集成到方向閥與底板之間，或用于先導閥與主閥間的阻尼調(diào)節(jié)。41417
功能優(yōu)勢
該閥具備流量調(diào)節(jié)范圍大、內(nèi)泄漏量小、調(diào)節(jié)力矩小等特點，能快速響應系統(tǒng)變化。進口或出口節(jié)流的選擇可通過安裝位置（6通徑）或型號（16/22通徑）實現(xiàn)，適配不同調(diào)速需求。例如，主流量控制時安裝于方向閥與底板之間；先導流量控制時連接先導閥與主閥。對稱設計的雙節(jié)流閥可同時管理兩條油路，提升系統(tǒng)協(xié)調(diào)性。6712
應用場景
Z2FS22適用于需要精確流量控制的液壓系統(tǒng)，如挖掘機、高空作業(yè)平臺等行走機械的調(diào)速回路，或機床、鍛壓設備的進給機構。其穩(wěn)定性和耐用性在高壓、大流量環(huán)境中表現(xiàn)突出，同時簡化了系統(tǒng)布局，降低維護復雜度。用戶可根據(jù)實際需求選擇帶刻度旋鈕或內(nèi)六角螺釘?shù)日{(diào)節(jié)方式。71822
Product Overview
The Z2FS22 double check throttle valve is a sandwich-mounted hydraulic control valve designed to regulate main or pilot flow rates in one or two working ports of a hydraulic system. By adjusting the throttle orifice area, it controls flow direction while allowing free reverse flow through integrated check valves. Suitable for vertical stacking, it offers flexible inlet/outlet throttling options with a nominal diameter of 22mm, operating pressure up to 31.5MPa, and flow capacity of 360L/min. Ideal for construction machinery and industrial hydraulics.412
Design Features
The valve features symmetrically arranged dual throttle-check units, including a valve body, throttle screw, adjusting spindle, and O-ring seals. Flow is precisely modulated via axial movement of the throttle spool; reverse flow bypasses through the check valve under spring force. Constructed from carbon steel, it supports mineral oil and phosphate ester fluids within -20°C to +80°C. Its compact sandwich design simplifies integration between directional valves and manifolds or as damping control in pilot circuits.41417
Performance Benefits
With broad flow adjustment range, minimal internal leakage, and low actuation torque, the valve ensures rapid system response. Inlet/outlet throttling modes are selectable by installation orientation (6mm size) or model variants (16/22mm), accommodating diverse speed regulation needs. Dual throttling paths enable synchronized management of parallel circuits, enhancing system efficiency. The design prioritizes reliability in high-pressure, high-flow environments.6712
Typical Applications
The Z2FS22 excels in applications demanding precise flow control, such as speed-adjustment circuits for excavators or aerial work platforms, and feed mechanisms in metalforming machines. Its robust performance under extreme conditions and modular configuration reduce maintenance efforts while optimizing space utilization. Users may select adjustment mechanisms like dial knobs or hex screws per operational preferences.71822
