Pressure control for fixed-head nitrogen sealing
Thread Content
For pressure control in a nitrogen sealing system, should dual-control of nitrogen pressure be used or a self-acting pressure regulator? Can these two be used simultaneously? Please, esteemed seniors, offer your guidance
My experience with stress relief: The Cv value is very low; one can use imported products or control valves. Pressure relief valve: regulating valve. Easy to turn on remotely. Soft seals are chosen for all of them.
Suggestion: Choose control regulating valves for greater precision
Selection should be based on specific design requirements. For normal-pressure nitrogen sealing, a self-pressurized type is sufficient
