Typical Applications
Altitude Valve
Model C201/CF201
The Model C201/CF201 Single Acting Altitude
Valve closes at a preset maximum water level to
prevent overflow of a ground storage tank or
reservoir and opens to refill when the water
level in the tank or reservoir lowers.
The modulating effect is evident only over the
last few inches of filling so that a gradual clo-
sure is achieved.Because of this modulatingeffect, the filling rate will be relatively slow as
the tank or reservoir water level approaches
shut off elevation.
This type of Altitude Valve should be used when
the supply pressure is appreciably higher (15
psi+) than the head developed by a full ground
storage tank or reservoir.

ATTENTION
1. If the altitude valve is not installed immediately
adjacent to the tank, reservoir, or basin; if a high filling rate is anticipated; or if the tank has overhead
fill, a separate static pressure sensing line should
be installed between the altitude pilot valve and the
tank or reservoir to insure that the altitude pilot
valve accurately senses the true tank head.
2. The pilot control discharges a small amount of
control water as the main valve piston moves to the
open position.Therefore, the vault should be provided with a drain or sump.
