The Sun Hydraulics RVESKQN (Material Number: RVESKQN) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precise pressure regulation. This valve remains normally closed until the inlet port pressure reaches the predetermined setting, at which point it begins to open to the tank port, effectively throttling flow to maintain regulated pressure. Notably, it features a vent port that enables remote control through other pilot or 2-way valves. The valve is characterized by its accuracy, low-pressure rise versus flow, smooth operation, and moderate speed. This product is particularly suitable for load-holding applications where zero leak valving on the vent port is required. It can handle maximum pressure at the tank port and is adaptable for cross-port relief circuits. The valve's design incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations of cavity/cartridge. It also includes a main stage orifice protected by a 150-micron stainless steel screen. The RVESKQN has a capacity of 25 gpm (95 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It exhibits minimal leakage at reseat with only 10 drops per minute (0.7 cc/min). The valve's response time is typically around 2 ms, and it demonstrates relative insensitivity to varying oil temperatures and contamination levels. Additional specifications include an adjustment range facilitated by up to 5 turns clockwise for increased settings and an installation torque requirement between 45-50 lbf ft (61-68 Nm).
