Series 8100 - Modulating Float Control Valves

• While similar to the Series 8000 On/Off Float Valves through the use of a rotary disc float control, the 8100 series provides modulating rather than on/off type action. In this way, level in the vessel can be continuously maintained within extremely narrow limits.

• Model 8101 Modulating Float Valve
• Model 8102 Modulating Float Valve
• Model 8104 Modulating Float Valve
• Model 8105 Modulating Float Valve
