HydraForce, a leader in hydraulic valve and manifold technology, has announced the launch of its new EHBL digital boom control valve. This advanced pressure control valve, featuring an electro-proportional relief mechanism, is designed to enhance hydraulic system performance and energy efficiency in machinery.
According to Brian Del Bene, Product Line Manager for Cartridge Valves at HydraForce, “The EHBL digital boom control integrates seamlessly into ISO 8643-compliant systems, offering both safety and efficiency. It supports smooth operation, energy conservation, and can be creatively utilized in hybrid energy recovery circuits.”
The EHBL valve is equipped with an integral pressure control feature that responds to hose ruptures by closing off, thereby protecting the hydraulic system. It employs electronic monitoring to assess fluid resistance on the rod side of the cylinder through a pressure sensor, dynamically adjusting pressure settings to maintain system stability and optimize efficiency.
This valve’s operations are managed via HydraForce’s EVDR plug-on controller, providing precise control over pressure rather than flow—a departure from traditional pilot-operated proportional poppet valves used in excavators. The EHBL valve is designed with a poppet seat for minimal leakage and a spool-type metering system for enhanced control.
The EHBL integrates within existing pilot-operated device spaces and includes a built-in check valve to facilitate free reverse flow. It is versatile, capable of serving both sequence and relief functions based on its plumbing configuration. The valve supports a flow rating of up to 120 gpm (454 lpm) and pressures up to 5500 psi (379 bar).
Field tests have demonstrated that the EHBL digital boom control valve can achieve a 4% increase in fuel savings, contingent on application specifics and continuous operation over an eight-hour period.
This innovation positions HydraForce at the forefront of hydraulic efficiency, offering a solution that not only meets operational demands but also contributes to significant energy savings.
