PRESSURE AND VACUUM RELIEF VALVES

KSPC

The pressure and vacuum relief valves manufactured by Korea Steel Power Corp. (KSPC) are designed, manufactured, and tested in accordance with the API 2000 standard. These advanced-design valves are available for both vent-to-atmosphere and pipe-away configurations, and serve as safety devices in response to pressure and vacuum variations in storage tanks. By opening precisely at calibrated set points, they protect tanks from damage due to overpressure or vacuum, minimize product loss by preventing leakage, and safeguard the environment from toxic gas emissions. They can be installed in combination with flame arresters and equipped with additional features such as dehumidifiers or steam jackets for heating.

At KSPC, we offer a wide range of pressure and vacuum relief valve models, specifically designed to meet various operational conditions and requirements.
