The Hydraforce 5278705 (5278705) is a cutting-edge hydraulic component designed for precision fluid control in various applications. This model, also known as the EHPR98G38XXX, serves as a direct-acting, spool-type, proportional pressure reducing and relieving valve. It is specifically crafted as a 3rd generation drop-in, flange-mounted cartridge valve that accommodates mineral-based or synthetic hydraulic fluids with lubricating properties. The design integrates the coil within the valve structure itself, which is not serviceable independently.
This valve's functionality stands out by allowing the regulated pressure to be proportional to the input electrical current across specified pressure ranges. It supports inlet pressures up to 34 bar (500 psi) with its standard plunger for applications demanding faster response and increased volume at the control port. For higher-pressure applications up to 69 bar (1000 psi), where decreased volume at the control port is necessary, a damped plunger variant is recommended to ensure stability and efficiency.
Key features of this model include its economical drop-in style which simplifies installation and maintenance processes. It also offers multiple mounting plate options and several regulated pressure ranges to suit diverse operational requirements. The quick response time of this valve makes it an ideal choice for systems requiring swift adjustments in pressure settings. Additionally, it includes options for retrofitting, screen additions, and a top-mounted connector which enhances its adaptability and ease of use while maintaining low leakage characteristics.
