    About Pressure Gauges
    industrial info icon

    Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

    Steam Pressure Gauges

    Designed for use with boilers, these gauges have a dual scale that displays pressure in psi and feet of H₂O and displays temperature in °F/°C.

    Low-Pressure Differential Gauges with U-Tube

    Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.

    High-Accuracy Pressure-Regulating Valves for Steam

    Image of Product. Front orientation. Pressure-Regulating Valves. High-Accuracy Pressure-Regulating Valves for Steam.
    Control steam line pressure with ±1 psi accuracy. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline. They meet ANSI/FCI 70-2 Class IV for tight shut-off (max. leakage rate of 0.01%). Install 1/4 NPT male pipe (not included) between the control valve and your downstream steam line.

    Image of Product. Front orientation. Pressure-Regulating Valves. Corrosion-Resistant Pressure-Regulating Valves for Steam.
    Regulate steam pressure in wet environments and harsh conditions with these valves that have a 316 stainless steel body for exceptional corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.
