The Sun Hydraulics RBACQCV (Material Number: RBACQCV) is a direct-acting, pilot relief cartridge valve designed to remotely control the pressure setting of other pilot-operated valves. This model is specifically suitable for systems requiring precise load holding applications and should be paired with higher flow valves due to its limited capacity to pilot flow. The valve is equipped with EPDM seals, making it compatible with phosphate ester fluids, but unsuitable for petroleum-based fluids, which may damage the seals. Featuring a 150-micron stainless steel screen protecting the main stage orifice, it ensures durability and reliability in operation. The RBACQCV can handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 2 milliseconds. It offers an adjustable range throughout its full capacity using W or Y controls unless a special setting is specified, which then becomes the maximum setting. The valve's construction incorporates Sun's floating style design to reduce risks of internal binding due to excessive torque or machining variations. Its corrosion-resistant options are available with stainless steel or zinc-nickel plated components identified by suffixes AP or LH respectively. This cartridge valve has a capacity of 0.25 gpm (1 L/min) and exhibits minimal leakage at 5 drops/minute (0.3 cc/min) at 110 SUS (24 cSt). Its installation requires specific torque settings for optimal performance: valve installation torque is between 30 \u2013 35 lbf ft (41 \u2013 47 Nm), adjustment screw internal hex size is 5/32 inch (4 mm), locknut hex size is 9/16 inch (15 mm), and locknut torque ranges from 80 \u2013 90 lbf in (9 \u201310 Nm). The model weighs approximately .30 lb (.15 kg), making it a robust yet lightweight solution for controlling hydraulic pressures effectively.
