210-16 & 610-16 Altitude Valve for Two Way Flow

Cla-Val Models 210-16 and 610-16 Altitude Valves control the high water level in reservoirs without the need for floats or other devices. They are non-throttling valves that remain fully open until the shut off point is reached. These valves close at a high water level, and open for return flow when the pressure at the valve inlet is less than the reservoir pressure.
