2W Vertical Float Level Control Valve
The following is a step by step narrated description of the Eliptix R-30-Y 2W Vertical Float Level
Control Valve installation, operation and maintenance processes.
The A.R.I. R-30 Series is a line of metal, diaphragm-operated, hydraulic control valves.
The valves are suitable for installation in agriculture, water transmission and waterworks systems
for irrigation, landscape and infrastructure applications.
The R-30 series has an innovative elliptic shaped diaphragm that integrates well with a wide variety
of regulating control pilots, solenoids and control accessories.
They are compatibility designed for water level control, flow control, electric & remote control as
well as pressure reducing & pressure sustaining operation.
The R-30-Y 2W Vertical Float Level Control valve is a hydraulic on/off control valve designed to
maintain a preset level of water in a tank or a reservoir, according to the position of the float valve.
Low water level causes the buoy to drop and the float valve to open; this issues a command that
opens the main valve. Rising level of water brings the buoy up, closes the float valve, and
commands the closure of the main valve.

R-30 Y
2.4. Initial Set-up - The Vertical Float Level Control Valve Application
1. The following is a general description of the R-30-Y 2W Level Control Application:
This ON/OFF Level Control Valve is an automatic control valve, designed to be opened and closed according to the
position of a float valve which is equipped with a buoy that floats on the reservoir water.
When the reservoir water level drops below the pre-set level the vertical float [5B] drops with it. As the float reach
the lower stopper (5E) the float valve [5C] opens, water from the control chamber flows out through the control
tube [7] and the vent port of the float valve [6] causing the main valve to open.
When the reservoir water level rises back to the pre-set level the vertical float [5B] floats with it. As the float reach
the upper stopper (5D) the float valve [5C] closes, water from the upstream 2-way ball valve [2] flows into the
control chamber causing the main valve to close.
2. Mount the float valve [5] on the reservoir/tank at the desired level.
3. Adjust the upper stopper (5D) to the required reservoir/ tank upper water level.
4. Adjust the lower stopper (5E) to the required reservoir/ tank lower water level.
Very Important - when in manual Open or Close Modes, the Control
Valve cannot respond to changes in the reservoir water level!
No.
