Knowing that the terminal pressure drop ratio for this particular model globe valve is 0.7 we can now predict that if the inlet pressure was 300 psi, flow would choke at 210 psi pressure drop (300 X 0.7 = 210). In order to properly size control valves for gas service, it is necessary to know at what pressure drop flow will choke.

Jacksonville, Florida (September 16, ) Natural gas systems are designed to follow strict codes requiring secondary protection features to prevent over-pressurization. These systems are designed to eliminate single point of failure modes, however, systemic failure can even cause these redundant systems to fail under the most extreme conditions.

WITT relief valves also stand out due to their high blow-off flow rates of up to 970m³/h. They can be used within a temperature range of -76° F to +518°F and even with very low pressures. These very low pressure valves can also be used in reverse, to maintain a constant gas pressure in a vessel, very accurately and very reliably.
