The Sun Hydraulics RVCAOHN (RVCAOHN) is a ventable, pilot-operated, balanced piston relief cartridge designed to function as a normally closed pressure regulating valve. This model is engineered to open to the tank port when the inlet pressure reaches its set point, thereby throttling flow and regulating pressure efficiently. It features a vent port that allows for remote control by other pilot or two-way valves, offering precise control with low pressure rise versus flow, smooth operation, and moderate speed. The RVCAOHN can accept maximum pressure at port 2 and is suitable for cross-port relief circuits, although users should consider spool leakage in such applications. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen; however, it is not recommended for load holding applications due to potential spool leakage. Back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio. This cartridge uses EPDM seals appropriate for systems with phosphate ester fluids but should not be exposed to petroleum-based fluids as this could damage the seals. The Sun floating style construction minimizes internal part binding due to excessive installation torque or machining variations. It fits into a T-11A cavity with a Series 1 capacity of 15 gpm (60 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at 4 gpm (15 L/min), and it has a typical response time of 10 ms. Valve leakage is minimal at specified conditions, with an adjustment range facilitated by five clockwise turns to increase settings. Installation requires specific torque values for both the valve and locknut components.

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.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- 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.
