Miniature ball valves are used to enable isolation of the gauge from the rest of the system, perhaps for removal for replacement or cleaning. These valves can be provided in brass or stainless steel with ¼" or ½" connections. It is important to double-check the valve pressure rating with the gauge to make sure they are compatible for the system pressure.
A siphon is used to help protect pressure gauges and other instruments from the effects of hot pressure media typical of steam applications. This works on the principle of steam condensate accumulating within the coiled area which buffers rapid temperature surges to the attached instrument.
Pressure snubbers are used to dampen the effect of system pulsation, slowing the surges into the gauge from sudden pressure spikes. One design we offer is adjustable providing the bonus of isolating the gauge for service or replacement. Pressure snubbers are available in brass and stainless steel and if circumstances require, they can be machined from other alloys.
