Pressure Accessories FAQ
Questions for siphons, snubbers, cooling elements, gauge cocks, valves, overpressure protectors, capillaries, manifolds, and calibration reports.
Which accessory protects a pressure gauge from high temperature?
A siphon tube is commonly used for steam service, while a cooling element or capillary can reduce heat transfer to the instrument. The best choice depends on process temperature, installation space, and whether remote reading is needed.
When should I use a pressure snubber?
Use a pressure snubber when the pressure signal has pulsation, sudden spikes, or rapid changes that may damage the gauge or make the pointer unstable. Snubbers help dampen the pressure impulse and improve readability.
What is the purpose of an overpressure protector?
An overpressure protector helps protect a pressure gauge from pressure exceeding its rated range. It is useful in systems where occasional pressure spikes may occur or where the gauge must be protected from accidental overload.
When is a manifold valve needed?
Manifold valves are used with pressure and differential pressure instruments for isolation, equalizing, venting, and calibration. Two-valve, three-valve, and five-valve manifolds are selected based on the instrument and process layout.
