The Sun Hydraulics RSHSCBV (RSHSCBV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve setting. This valve controls the pressure at port 1 in relation to the drain port 3, remaining insensitive to back pressure at port 2 up to the valve setting. It can function as a pressure regulator, replacing 2-port relief valves when there is pressure in the return line. The RSHSCBV features interchangeable three-port sequence cartridges with identical flow paths and cavities for its frame size, and it incorporates Sun's floating style construction to reduce binding risks due to installation torque or machining variations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and it can handle maximum pressures of up to 5000 psi (350 bar) at port 3, which directly adds to the valve setting at a 1:1 ratio. This makes it suitable for load holding applications and cross-port relief circuits. The valve's design ensures immunity from cavitation-related issues like noise and manifold erosion since modulation occurs within the cartridge itself. This model has a capacity of 60 gpm (240 L/min) and operates effectively with a response time typically around 10 ms. It features an adjustment system that allows for increasing settings with five clockwise turns, ensuring precision control over hydraulic operations. The RSHSCBV includes Viton seals for durability under various conditions and requires specific installation torques for optimal performance.
