DESCRIPTION AND FEATURES
Experience superior flow regulation with our state-of-the-art Advanced Hydraulic Differential Relief Valve, expertly designed by Jiangsu Erma Hydraulic Components Co., Ltd. This innovative valve activates when the pressure at 'P' reaches a specified threshold. Thanks to the distinctive area difference between the inside and outside of the spool, the valve opens in relation to the seat, initiating overflow from P to T. Engineered for rapid response and minimal internal leakage, this valve offers a significantly reduced pressure drop compared to conventional direct-acting relief valves, making it ideal for high-flow environments.
