The Hydraforce EHPR08-33-6T-N-00 (5278130) is a direct-acting, spool-type, proportional pressure reducing/relieving valve designed to offer precise control over hydraulic system pressures. This model allows for free flow from port 1 to port 3 when the coil is de-energized. Upon energizing the coil, port 2 connects to port 1, and increasing current to the coil proportionally increases the controlled reduced pressure. Should the pressure at port 1 exceed the set value induced by the coil, excess pressure is relieved to port 3. Notably, this valve features both manual override capabilities and optional waterproof E-Coils rated up to IP69K, making it suitable for robust applications in demanding environments. It operates with a variety of voltage options including standard 12 and 24-volt coils. The valve's industry-common cavity ensures compatibility with existing systems, enhancing its utility across various setups. Pressure ratings for this model are substantial, with a maximum of 241.3 bar (3500 psi) at port 2 inlet and burst pressure reaching up to 827.4 bar (12000 psi), ensuring reliability under high-pressure conditions. The valve also supports a maximum flow rate of 4.0 lpm (1.0 gpm) from port 1 to port 3 when de-energized. Hydraforce's EHPR08-33-6T-N-00 operates efficiently within a fluid temperature range of -40°C to +100°C with Buna N seals and can handle a wide range of fluid viscosities from 7.4 to 420 cSt, accommodating different hydraulic fluids with lubricating properties. This versatility in operating conditions coupled with robust design specifications makes it an optimal choice for varied hydraulic applications requiring precise pressure management and reliability.
