Product Info
Parker Hannifin
Parker’s piloted load holding/counterbalance valves are a combination of a relief, sequence, and flow control valve that can handle pressures up to 420 bar (6000 psi) and flows up to 350 lpm (90 gpm). These robust valves allow the operator to maintain control of the load by preventing it from overrunning the pump while also protecting against thermal expansion. The wide selection of pilot ratios enables the valve to open based off a given backpressure specific to the application, which could be much lower than the spring pressure setting. This feature allows predictable and consistent control of a load throughout its lowering cycle.
