FLOAT PILOT INSTALLATION

To protect the float ball from wave action within the tank, it is highly recommended that the float be installed in a stilling well. This is especially critical if the fill line exits into the top of the tank.

VALVE INSTALLATION

For maximum efficiency, the OCV control valve should be mounted in a piping system so that the valve bonnet (cover) is in the top position. Other positions are acceptable but may not allow the valve to function to its fullest and safest potential.

In particular, please consult the factory before installing 8" and larger valves, or any valves with a limit switch, in positions other than described.

Model 814 Float Pilot

The OCV Model 814 Float Pilot is a float-actuated, three-port, rotary disc pilot designed to provide on-off action to an OCV Model 65 main valve.

It features the following:

• Integral mounting plate to facilitate installation within the tank.
• Designed for mounting above the fluid level to prevent a cross-connection.
• High and low level points are independently adjustable, allowing for optimum tank cycling.

The basic principle of operation of the 814 pilot is quite straightforward. There are three sets of ported passages in the pilot body, and matching sets in the lapped rotary disc.

• With the float "down", the "S" port is blocked, and the "C" port is connected to "E" port. This allows the pilot to vent the diaphragm chamber of a main valve or auxiliary pilot, thus opening the main valve.
• With the float "up", the "E" port is blocked, and "S" is connected to "C" port. This allows the pilot to pressurize the diaphragm chamber of the main valve or auxiliary pilot, thus closing the main valve.
