Do you have questions about gauges?

Having the right information about the status of steam or hydronic systems is an important part of running and maintaining them. Without that information problems might go unidentified, leading to any number of issues. With steam and hydronic systems, the most common readings needed are for temperature and pressure. These readings can be taken separately using a temperature or pressure gauge, or they can be measured simultaneously with a tridicator.

For steam service, pigtail syphons are often added to pressure gauges to limit the direct contact that the gauge has with high temperature steam. For protection against pressure surges, snubbers are available for use in air, water, and steam applications. 

Contact Keystone to inquire about pig tails, snubbers, and other gauge accessories.
