Accurate Flow Control | A pressure regulator to start, stop, and regulate flow rate within pipelines, preventing sudden pressure surges of liquids or gases, to ensure safe and efficient operation of industrial units Reliable and Durable | Our valves are 100% Helium leak tested to 1 x 10-4 ml/s to guarantee reliable performance and durability. Corrosion Resistant | Stem seal features 316 stainless steel to improve corrosion resistance. The thread includes a Fluorocarbon (FKM) o-ring and Polytetrafluoroethylene (PTFE) coating that bolsters the corrosion resistance of this needle valve. Compact Size | Compact size allows this pressure relief valve to fit easily into various pipeline systems within an industrial unit. Excellent Durability | This shut-off valve is designed to stand up to high temperature and high-pressure settings. It carries a 10000 psi pressure rating at 200 degrees F maximum, making it an ideal valve for industrial and manufacturing facilities.
