The Sun Hydraulics RVESCBN (Material Number: RVESCBN) is a ventable, pilot-operated, balanced poppet relief cartridge valve designed for precise pressure regulation in hydraulic systems. This normally closed valve begins to open to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to maintain consistent pressure levels. A unique feature of this valve is its vent port 3, which facilitates remote control via other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, the RVESCBN operates smoothly and quietly with moderate speed. This relief cartridge is particularly suitable for load-holding applications, provided that any valving on vent port 3 ensures zero leakage. It can handle maximum pressure at port 2, making it ideal for cross-port relief circuits. The valve's performance remains reliable under varying oil temperatures and contamination levels due to its robust design. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring longevity and durability. The RVESCBN incorporates Sun's floating style construction to minimize risks of internal part binding from excessive installation torque or machining variations. It supports a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 25 gpm (95 L/min). The factory-set pressure settings are established at a flow rate of 4 gpm (15 L/min), with an adjustment range facilitated by a screw with an internal hex size of 5/32 inches (4 mm). This model also features a locknut hex size of 9/16 inches (15 mm) with an installation torque specification between 45-50 lbf ft (61-68 Nm). With minimal maximum valve leakage at reseat and rapid response time, this valve ensures efficient operation across various hydraulic applications.

Ventable, pilot-operated, balanced-poppet 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.

  • Because the modulating occurs inside the cartridge, these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
  • Suitable for use in load holding applications, providing that any valving on the vent port (port 3) is zero leak.
  • Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
  • A remote pilot relief on port 3 (vent) will control the valve below its own setting.
  • Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
  • Main stage orifice is protected by a 150 micron stainless steel screen.
  • Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
  • 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.
