The Sun Hydraulics RVIACAV (RVIACAV) is a ventable, pilot-operated, balanced piston relief cartridge designed for pressure regulation applications. This normally closed valve opens to the tank port when the inlet pressure reaches its set point, effectively throttling flow to maintain desired pressure levels. It features a vent port that allows for remote control via other pilot or two-way valves, making it versatile and adaptable in various hydraulic systems. With characteristics such as accuracy, low-pressure rise versus flow, smooth and quiet operation, and moderate speed, this valve is suitable for precise control environments. The RVIACAV can accept maximum pressure at port 2 and is appropriate for use in cross-port relief circuits; however, users should consider spool leakage in these applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen to ensure durability and longevity of the valve. It is important to note that this valve should not be used in load-holding applications due to potential spool leakage issues. Cartridges with EPDM seals are intended for systems using phosphate ester fluids and are not compatible with petroleum-based fluids. This model incorporates Sun's floating style construction to minimize internal binding risks from excessive installation torque or cavity machining variations. It has a capacity of 120 gpm (480 L/min) and can operate at pressures up to 5000 psi (350 bar). The typical response time is around 10 ms, with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). The valve's design includes an adjustment screw internal hex size of 5/32 inch (4 mm), locknut hex size of 9/16 inch (15 mm), and requires specific torque settings for installation and adjustment purposes.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.

  • A remote pilot relief on port 3 (vent) will control the valve below its own setting.
  • Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
  • Main stage orifice is protected by a 150 micron stainless steel screen.
  • Relief valve setting must always be higher than pilot valve setting.
  • Not suitable for use in load holding applications due to spool leakage.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
