The Sun RVGS-LCN is a high-capacity, pilot-operated, balanced piston relief valve designed for robust hydraulic systems. It functions to limit system pressure to a specific, adjustable set point. When system pressure reaches the valve setting, the valve opens, diverting excess flow to the tank and protecting components from over-pressurization. Its balanced piston design ensures consistent performance and stability, even with significant back pressure at the tank port. This ventable cartridge valve is ideal for applications requiring reliable pressure control and system protection.
