Specification

DESCRIPTION AND FEATURES
Experience the ingenuity of our pilot-operated overflow valve, meticulously crafted for excellence. As soon as the pressure at 'P' meets the valve's setting, the pilot spool elegantly begins to open, followed by the main spool's seamless transition due to the pressure differential between its interior and exterior. This orchestrated performance results in an efficient overflow from P to T. Renowned for its rapid opening and closing rates, this valve exhibits exceptionally low internal leakage, making it the ideal choice for high-pressure, large-flow hydraulic systems.
