The Sun Hydraulics RSHSKNN (RSHSKNN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port exceeds the valve setting. This valve effectively controls the pressure at port 1 relative to the drain port 3, while remaining insensitive to back pressure at port 2 up to the valve setting. It is suitable for load holding applications and can replace two-port relief valves in systems with return line pressure. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and it features Sun's floating style construction to prevent internal binding due to excessive installation torque or machining variations. The RSHSKNN model has a maximum operating pressure of 5000 psi (350 bar) and a response time of approximately 10 milliseconds. It supports a capacity of up to 60 gpm (240 L/min) and incorporates a cavity T-17A design with Series 3 compatibility. The valve's adjustment can be increased with five full clockwise turns, and it includes an internal hex size for adjustment screw of 5/32 inches (4 mm). Additionally, it features a locknut hex size of 9/16 inches (15 mm), with locknut torque specifications between 80-90 lbf-in (9-10 Nm). The model weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits for optimal performance. This sequence valve is adept in cross port relief circuits, making it versatile across various hydraulic applications where precise pressure control is critical.
