The Hydraforce 5278704V (5278704V) is a sophisticated hydraulic component, specifically a direct-acting, spool-type, proportional, pressure reducing relieving valve from Hydraforce's innovative lineup. Designed as a 3rd generation drop-in, flange-mounted cartridge type valve, it is tailored for use with mineral-based or synthetic hydraulic fluids that have lubricating properties. This model stands out due to its integral coil which forms an essential part of the valve assembly but is non-serviceable, emphasizing its reliability and ease of use in various hydraulic setups.
The 5278704V operates effectively with the regulated pressure being proportional to the input electrical current within specified pressure ranges. It offers versatility through its standard plunger recommended for applications with inlet pressures up to 34 bar (500 psi), ideal for scenarios requiring 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 suggested to maintain stability and performance.
Among its notable features are its economical drop-in style which simplifies installation processes, multiple regulated pressure ranges allowing for customization according to specific requirements, and quick response time that enhances operational efficiency. Additionally, it includes options such as mounting plates for secure installation, retrofit options for EHPR98T38 models, a top-mounted connector for better accessibility in complex configurations, and low leakage characteristics which enhance its overall efficiency and reliability in demanding hydraulic environments.
