Technical overview
DK-LOK DK-RVS high pressure relief valve is a factory-set safety valve that discharges excess pressure when the system exceeds the set point, protecting instruments and downstream devices. This valve supplied is made in SS316 with 1/2" male x female NPT end connections (MF8N) and is factory set at 10,000 psig. It uses spring code KK11, which covers an adjustable spring range of 10,000–15,000 psig, allowing controlled setting within the spring range when required. The valve is sealed with a pressure tag after setting and is suitable for high-pressure hydraulic systems and test bench applications where stable relief and dependable reseal performance are required.
