Product Description

Jiangsu Erma Hydraulic Components Co., Ltd.

Welcome to the world of Jiangsu Erma Hydraulics, a leader in the production of threaded cartridge valves and precision spare parts. With over two decades of expertise in production and research and development, we are equipped with over 200 state-of-the-art production and processing machines. Our key processes utilize top-of-the-line imported equipment from esteemed brands like American Hardinge, Swiss Schaublin, Japanese STAR, Citizen, Korean Doosan, Sunnen Honing, and Japanese Mitutoyo. Complementing this, we boast more than 50 sets of specialized measuring and testing equipment. Our annual output exceeds one million units of diverse hydraulic components, including safety valves, overload valves, relief valves, balance valves, logic valves, solenoid valves, one-way valves, throttle valves, and pressure reducing valves. These products are indispensable in multi-way valves, gear pumps, steering gears, cylinders, and comprehensive hydraulic systems.

Specification

DESCRIPTION
Our Advanced Pressure Control Valves are engineered to perfection. When the pressure at 'P' reaches the set threshold, the pilot spool begins to open, followed by the main spool due to a pressure differential. This intelligent design achieves overflow from P to T. These valves are designed for high-speed opening and closing, with minimal internal leakage, making them ideal for high-pressure and large-flow hydraulic systems.
