What is your application?
Level Gages & Water Columns
Water columns, flat glass, prismatic, Simpliport®, Eye-Hye® remote, and Levalarm systems for boiler and pressure vessel service.
Water Columns (Steel)
Steel water columns combining boiler water level indication and alarm in a single unit. The industry standard for high-pressure steam boiler service.
Cast Iron & Steel Water Columns
Cast iron and steel water columns for lower-pressure boiler applications. Multiple connection configurations and pressure ratings available.
Eye-Hye® Remote Level System
Electronic remote level indication system — view boiler water level from a distance without direct line-of-sight to the gage glass.
Flat Glass Level Gages
Transparent flat glass gages for clear visual liquid level indication in boilers and pressure vessels. Wide range of pressure and temperature ratings.
Prismatic (Reflex) Level Gages
Reflex prismatic gages for high-contrast single-phase liquid level indication. Prism glass reflects vapor as bright silver and liquid as dark.
Simpliport® Level Gage
Clark Reliance's patented single-port gage design. Simplified installation and maintenance with a single vessel connection instead of two.
Levalarm Level Alarms
High and low water level alarms for steam boilers and pressure vessels. Provides early warning of dangerous water level conditions.
Valves & Steam Traps
Gage cocks, isolation valves, and steam traps to complete your boiler instrumentation installation.
Gage Cocks & Gage Valves
Gage cocks and isolation valves for connecting and isolating level gages from boiler pressure. Multiple pressure ratings and end connections.
Isolation Valves (450 / 1500 / 3000 psi)
High-pressure isolation valves rated to 450, 1500, and 3000 psi for demanding boiler and process applications.
Steam Traps
Efficient steam traps for condensate removal in steam distribution systems. Reduces energy waste and improves system efficiency.
