The Sun Hydraulics RPESKCV (Material Number: RPESKCV) is a pilot-operated, balanced-poppet relief cartridge valve designed to regulate pressure in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the specified setting, allowing for precise and smooth pressure control with minimal noise and low pressure rise versus flow. The internal modulation within the cartridge makes it resistant to cavitation issues such as noise and erosion, while its design allows for maximum pressure acceptance at port 2, making it suitable for cross-port relief circuits. The valve's performance remains stable despite variations in oil temperature and contamination, thanks to its robust construction featuring a 150-micron stainless steel screen protecting the main stage orifice. The RPESKCV is particularly effective in load-holding applications due to its backpressure sensitivity at a 1:1 ratio with the valve setting. It incorporates Sun's floating style construction, reducing risks of internal binding from installation torque or machining variations. The valve has a capacity of 25 gpm (95 L/min) with a maximum operating pressure of 5000 psi (350 bar). Its response time is typically around 7 ms, with minimal leakage at standard conditions. Adjustments can be made through W or Y controls across the full range unless a special setting is specified. Installation requires specific torque settings and hex sizes for both the valve body and adjustment components. Weighing just .30 lb (.15 kg), this compact yet powerful component is an essential part of any system requiring reliable pressure regulation.
