該閥在緊湊式螺紋插裝閥結(jié)合了減震閥和通過止回閥實(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)到閥門設(shè)定,閥門啟動(dòng)打開通往油箱端口(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.
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 400 bar .
