ABOUT EF1415
The EF1415 is a spring-loaded pressure safety valve (PSV) designed for overpressure protection of pressure vessels, process equipment and piping systems in accordance with API 520, API 521, API 526 and ASME Section VIII.
Available in sizes from ½" x 1" to 16" x 20" and pressure classes from Class 150 to Class 2500, the EF1415 can be configured for a wide range of industrial services, including demanding pressure, temperature and corrosion conditions.
A broad selection of body materials and project configurations allows the valve to be adapted to the required process conditions, applicable code and project specification. Final selection and sizing should be based on the fluid, set pressure, relieving capacity, temperature, backpressure and installation requirements.
