814 On/Off Float Pilot 814
The 814 is a float-actuated, three-port pilot that controls the opening and closing of the main valve. The float rides freely on a vertical rod, with adjustable stop collars above and below. When the float reaches the upper stop, it moves the linkage up, rotating the pilot to close the main valve. When the float falls to the lower stop, it moves the linkage down, rotating the pilot to open the main valve. Between the two stops, the pilot, hence the main valve, remains in its last position. The 814 pilot directly operates the main valve on sizes 1 1/4″-6″. On valve sizes 8″ and larger, the 814 operates an auxiliary 3-way pilot to control the main valve.
- Two port, rotary disc design
- Can be valve-mounted or remote-mounted
- Adjustable drawdown between opening and closing points
- Counterweighted linkage allows for additional float rods
