產(chǎn)品描述：

該閥在緊湊式螺紋插裝閥結(jié)合了減震閥和通過(guò)止回閥實(shí)現(xiàn)補(bǔ)油的典型功能。在壓力下的泄壓功能，它是通過(guò)一個(gè)側(cè)入式鼻排氣閥完成的，由于智能導(dǎo)流板設(shè)計(jì)實(shí)現(xiàn)非常低的壓力上升。當(dāng)壓力在高壓端口（1）達(dá)到閥門(mén)設(shè)定，閥門(mén)啟動(dòng)打開(kāi)通往油箱端口（2）。在自由反向液流中一個(gè)非常輕的偏置彈簧允許液流易于從鼻端流通到側(cè)端（2 到1）。高精度加工保證快速響應(yīng)負(fù)載變化，有限遲滯和減少內(nèi)部和外部泄漏。 The valve combines in one compact insert cartridge the typical function of shock relief valve and anti-cavitation through the check valve. In the pressure relief function it’s a side-in nose-exhaust valve, with very low pressure rise thanks to the smart deflector design. When the pressure at the high pressure inlet(1) reaches the valve setting, the valve starts to open to tank (2). In the free reverse flow function a very light bias spring allows for ease of flow passage from nose to side (2 to 1). High precision machining guarantees quick response to load changes, limited hysteresis and reduced internal and external leakage.

產(chǎn)品優(yōu)勢(shì)

錐閥經(jīng)過(guò)熱處理硬化并經(jīng)過(guò)精密加工，保證更低的內(nèi)泄漏及更長(zhǎng)的使用壽命。外部零件外表面都是經(jīng)過(guò)鍍鋅處理和防腐蝕處理。所有零部件均采用高強(qiáng)度鋼材制造。結(jié)構(gòu)緊湊、體積小。壓力由生產(chǎn)工廠設(shè)定，出廠后不可調(diào)節(jié)?？蛇x的彈簧壓力范圍最大至420bar。

Poppet is hardened and ground to guarantee minimal wear and to extend service life. All external surfaces are zinc plated and corrosion-proof. All valve parts are made of high strength steel. Compact size. Pressure setting is pre-adjusted by the factory and cannot be changed. Optional spring ranges to 420 bar .
