Honeywell L91B1050 Pressuretrol Controller is a modulating pressure operating controls designed for liquid, air, and non-corrosive gases regulation. Suitable for use with steam, air, and non-combustible gases, or other fluids non-corrosive to the bellows material (phos-bronze for 300 psi models).
DO NOT use with combustible mediums or any substance chemically harmful to the bellows material (phos-bronze for 10-300 psi models, brass for other pressure range models).
Features:
- Has an adjustable proportioning (throttling) range to allow the selection of desired pressure control range.
- Large, easily read scaleplates in both U.S. customary (oz/sq. in., psi, or in. Hg) and metric (kPa, MPa, or mm Hg) units.
- Operating Range: 5 to 150 psi
- Proportioning (Throttling) Range at Midscale: 5 to 23 psi
- Maximum Surge Pressure: 225psi
Tim Sheth –
Solid pressuretrol controller! It was easy to install and calibrated perfectly. Plus, delivery was fast, which is always a bonus.
