The Sun Hydraulics RSHEBBV (RSHEBBV) is an air-controlled, pilot-operated, balanced piston sequence valve designed to utilize compressed air over a diaphragm for pressure control instead of an adjustable spring. The air signal is introduced through a port located in the hex end of the cartridge, enabling secondary circuit flow once the inlet port 1 pressure surpasses the valve setting. This sequence valve manages pressure at port 1 relative to the drain port 3, maintaining insensitivity to back pressure at port 2 up to the valve setting. It can also substitute for two-port relief valves under conditions of return line pressure. As pilot flow increases with rising inlet pressure at port 1 compared to drain port 3, it offers explosion-proof remote control capabilities with a hydraulic-to-air setting ratio of 20:1. The RSHEBBV model integrates Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations. This model features a T-17A cavity and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). Its maximum operating pressure reaches 2000 psi (140 bar), and it demonstrates a typical response time of approximately 10 ms. The maximum allowable air pilot pressure is capped at 150 psi (10.5 bar), while the drain port's maximum permissible pressure is set at 1000 psi (70 bar). Installation requires a torque between 150 and 160 lbf ft (203 and 217 Nm), and it weighs approximately 1.50 lb (0.70 kg). The RSHEBBV model ensures functional interchangeability across all three-port sequence cartridges within its frame size, providing consistent flow paths and cavity compatibility.
