Conbraco 20-602-01 Chain Lever Water Gauge Top Valve 3/4" NPT Bronze

The Conbraco 20-602-01 is a replacement top valve only for the 20-602 Series chain lever boiler water gauge. Designed for use on large steam boilers where the water column is beyond convenient reach, this 3/4" NPT cast bronze valve is a direct service component for maintaining and repairing existing 20-602 gauge assemblies. The -01 suffix designates this as a top valve only — glass, rods, and bottom valve are sold separately.

Key Features:

• Top valve only — replacement component for 20-602 Series water gauge sets (suffix -01)
• 3/4" NPT male pipe connection — constructed from B-584 cast bronze for durability and corrosion resistance
• High pressure rating — 250 psig at 400°F and 500 psig at 100°F (subject to gauge glass limitations)
• Chain lever operated — lever on a standard 12-foot chain allows the operator to open and close valves that would otherwise be beyond reach
• Quarter-turn valve stem — provides quick, reliable shutoff operation
• PTFE reinforced gauge glass gaskets standard — high-pressure glass included with full sets
• Compatible glass OD: 3/4", standard glass length: 16"

This valve is suited for industrial boilers, steam generators, and pressure vessels requiring visual liquid level monitoring. Water gauges of this type are required by the ASME Boiler and Pressure Vessel Code on steam boilers. Also marketed under the Apollo Valves brand. Cross-reference: 20602, CO-20-602-01.
