PARKER RD102S18 CARTRIDGE VALVE

Parker’s selection of direct acting relief valves are fast acting and designed for continuous duty applications with pressures up to 420 bar (6000 psi) and flows up to 200 lpm (53 gpm) in a variety cavity sizes. The variety of pressure adjustment styles available makes these valves an economical solution for clipping pressure spikes and can handle up to full system flow if needed. Poppet style direct acting valves have low leak conditioned seats and are ideal port reliefs in cylinder control applications. Parker’s small, low flow, direct acting valves perform well when controlling pilot circuits or limiting load sense pressure.

Additional Technical Insight:
Full flow direct acting relief valves can be used as a main system relief valves in low flow circuits.  Direct acting valves are fast acting, therefore, these devices and can be an economical solution for clipping pressure spikes. Poppet style direct acting valves have low leak conditioned seats and are often used as a port relief in a cylinder control applications. Small, low flow, direct acting valves are ideal for controlling pilot circuits or limiting load sense pressure.
