Automatic Control Valves
A14A Altitude with Rate of Flow Control Valve
Altitude control with integral flow rate limiting.
Product Description
The A14A combines altitude level control with a rate of flow limiter in a single valve. The altitude pilot closes the valve when the tank is full; the flow pilot limits the fill rate to protect the supply main during peak demand. This combination prevents over-demand from elevated storage while maintaining full altitude control. Used at elevated tank inlets where the supply main has limited spare capacity.
