该阀在紧凑式螺纹插装阀结合了减震阀和通过止回阀实现补油的典型功能。在压力下的泄压功能,它是通过一个侧入式鼻排气阀完成的,由于智能导流板设计实现非常低的压力上升。当压力在高压端口(1) 达到阀门设定,阀门启动打开通往油箱端口(2)。在自由反向液流中 一个非常轻的偏置弹簧允许液流易于从鼻端流通到侧端(2 到1)高精度加工保证快速响应负载变化,有限迟滞和减少内部和外部泄漏。 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.
