Item #: E6B060ZN409

Product Info

Parker Hannifin

Parker’s vented to atmosphere load holding/counterbalance valves are a combination of a relief, sequence, and flow control valve that can handle pressures up to 350 bar (5000 psi) and flows up to 113 lpm (30 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 at pressures much lower than the spring pressure setting, allowing consistent control of the load throughout its lowering cycle. Because these valves spring chamber are vented to atmosphere, the valve will not be affected by changes in return pressure. Parker’s vented load holding valves are ideal in closed center circuits where there is need to control pressure using an auxiliary relief valve.
