The Sun Hydraulics RVGAMKN (RVGAMKN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when inlet port 1 pressure reaches the set level, effectively throttling flow to maintain desired pressure. It includes a vent port 3 for remote control via other pilot or two-way valves, allowing for versatile application and control. The valve is known for its accuracy, minimal pressure rise versus flow, smooth operation, quiet performance, and moderate response speed. The RVGAMKN can handle maximum pressure at port 2, making it suitable for cross-port relief circuits while considering spool leakage. However, it is not recommended for load-holding applications due to potential leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen to ensure durability and reliability in operation. It features Sun's floating style construction to reduce internal part binding caused by excessive installation torque or machining variations. This cartridge accommodates systems with phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based substances as they can damage the seals. With a cavity T-17A series 3 capacity of up to 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), the valve offers robust performance. Factory settings are established at 4 gpm (15 L/min), with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time is approximately 10 milliseconds. Installation specifications include a valve hex size of 1\u00bc inches (31.8 mm), an installation torque of 150-160 lbf\u00b7ft (203-217 Nm), and an adjustment screw internal hex size of ^5/32 inches (4 mm). The model weighs approximately 1.60 lb (0.70 kg) and comes with an optional Viton seal kit under material number 990017006 for enhanced compatibility with various hydraulic fluids.

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.
