sight glass level gauge valves for boilers

Sight glass level gauge valves -gauge cock valve are used to isolate a level gage from its host process for maintenance, inspection, and other ancillary operations. Water Gauge valve cocks are used for water level gauge (reflex glass level gauge, transparent glass level gauge, glass tubular level gauge) . is type of needle valve, have isolating ball inside, once the glass broken, the ball will block the water flow out.
