The SUN LPDC-XHN is a high-performance, pilot-operated, proportional relief valve designed to limit pressure in a hydraulic circuit. As a normally closed, poppet-type cartridge valve, it provides continuous and precise pressure control in response to a variable electrical input signal. This valve is engineered for excellent stability and low leakage, making it ideal for protecting hydraulic components from overpressure. Its proportional nature allows for dynamic pressure adjustments, suiting a wide range of industrial and mobile applications where accurate pressure management is critical. The LPDC-XHN is designed for installation in a standard Sun T-11A cavity.
