Typical Components: Ball, Gate, Globe, Check, Choke, Butterfly Valves and Actuators.
Components are enclosed in an insulated tank and immersed in liquid nitrogen, with 100% Helium as the search gas. Monitoring for Seat Leakage, Temperature and Pressurisation is carried out by Vaseco's unique ETS remote computer systems.
The emission testing is carried out by a Helium Mass Spectrometer, and emissions data is recorded. This method of testing can detect < 5ppm of the trace gas.
