High-Accuracy Low-Pressure Gauges
Dual Scale With Bottom Connection (Flange Mount)
Bottom Connection (Flange Mount)
Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes with these high-accuracy gauges. Mount them with the dial face upright.
Gauges with 304 stainless steel case or polyester plastic case have better corrosion resistance than gauges with steel case.
Gauges with safety case blow out in the back under excess pressure, protecting the operator in front.

Low-Pressure-Regulating Valves for Water
- For Use With: Water
- Temperature Range: 0° to 120° F
Designed for excellent performance at low pressures, these valves respond to even the slightest inlet pressure changes to maintain a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have an internal strainer to trap debris.
