The Hydraforce 5129904 (5129904) is a sophisticated pilot-operated, spool-type proportional pressure reducing/relieving valve designed for hydraulic systems. This drop-in, flange-mounted cartridge valve is optimized for use with mineral-based or synthetic hydraulic fluids that possess lubricating properties. The valve features an integral, non-serviceable coil which plays a crucial role in its operation. The regulated pressure of this valve is directly proportional to the input electric current, allowing precise control over hydraulic pressures within the system. Operationally, the Hydraforce 5129904 functions by allowing flow from port 3 to port 4 without applied current while blocking port 2. When the coil is energized, it connects port 3 to port 2 and controls the pressure at port 3 based on the amount of current applied. Should the pressure at port 3 exceed the coil's setting, excess pressure is relieved to port 4. Notably, any back pressure at port 4 adds to the overall pressure setting in a one-to-one ratio, enhancing its versatility in various hydraulic setups. This model comes standard with both 12 and 24-volt coils and offers several user-friendly features such as multiple push-on termination options and an optional lockdown flange for enhanced stability. An optional 233-micron mesh screen can also be included for additional filtration benefits. Designed with an integral waterproof coil, the Hydraforce 5129904 ensures reliable performance even in demanding environments, making it an ideal choice for applications requiring precise pressure regulation and reliability.
