OVERVIEW 1. Two-way hydraulic pool valve (VF) Maintains a constant pool level. The valve is located in the filling or emptying line. Basic hydraulic double-chambered valve with multi directional ball valve, flow regulator valve or needle valve and 2 way float. N.O. two-way hydraulic command does not enable complete opening, as there is always pressure in the valve closing chamber. A tube running between the valves (preferably 8 mm. and larger) is required for command. Valve in the filling line: When the level drops, the float opens a larger passage and reduces command pressure, which causes the valve to open. When the level rises, the float increases the pressure and closes the valve. Valve in the emptying line: When the level drops, the float increases the pressure and closes the valve. When the level rises, the float opens a larger passage and reduces the command pressure, causing the valve to open. Broad flow range (see table under Technical Data). Installing a calming device around the float to restrain the wave effect is recommended. Installing an external command water filter in addition to the existing flushing in-line filter installed in all C-Valves is recommended. Can be operated by hydraulic or electrical remote control. In installations where downstream pressure is low, installing an orifice in the Quikcoup coupling downstream of the valve to maintain a positive valve pressure is recommended. Closure can be restrained in the event of remote control. The valve shall be installed in-line and shall be supplied to the installation site accompanied by double - grooved connection pipes to be welded to the line or with Quikcoup flanges. 2. Three-way hydraulic pool valve (VH) Maintains pool level within the desired range. The valve is located in the filling or emptying line. Basic hydraulic double-chambered valve with multi directional ball valve, and 3-way float. N.C. or N.O. 2 x 6 mm. tubes are required for command: One for feeding pressure into the float, and the other for command from float to valve. N.C. valve: When the valve is used to fill the pool, as the level rises the valve ventilates the command pipe and the valve closes. When the float drops, the valve pressurizes the command pipe and (fully) opens the valve. N.O. valve: When the valve is used to fill the pool, as the level rises the valve pressurizes the command pipe and the valve closes. When the float drops, the valve ventilates the command pipe and (fully) opens the valve. N.C. valve: When the valve is used to empty the pool, as the level drops the valve ventilates the command pipe and the valve closes. When the float rises, the valve pressurizes the command pipe and (fully) opens the valve. N.O. valve: When the valve is used to empty the pool, as the level drops the valve pressurizes the command pipe and the valve closes. When the float rises, the valve ventilates the command pipe and (fully) opens the valve. Broad flow range (see table under Technical Data). Installing a calming device around the float to restrain the wave effect is recommended Installing an external command water filter in addition to the existing flushing in-line filter installed in all C-Valves is recommended. Can be operated by hydraulic or electrical remote control. The downstream partitioning valve can be obviated if the system is on a decline. In installations where downstream pressure is low, installing an orifice in the Quikcoup coupling downstream of the valve to maintain a positive valve pressure is recommended. Closure can be restrained in the event of remote control. The valve shall be installed in-line and shall be supplied to the installation site accompanied by double - grooved connection pipes to be welded to the line or with Quikcoup flanges. 3. Four-way hydraulic pool valve (FW) Maintains pool level within the desired range (double level). The valve is located in the filling or emptying line. Basic hydraulic double-chambered valve with multi directional ball valve, and 4- or 5-way float. N.O. 3 x 6 mm. tubes are required for command: One for feeding pressure into the float, and two for command from the float to the valve chamber. Filling the pool: When the level drops, the float ventilates the valve's closing compartment and pressurizes the opening chamber, which causes the valve to fully open even at very low pressures (about 4m.). When the level rises, the float ventilates the valve's opening chamber and pressurizes the closing chamber, closing the valve even at very low pressures (about 4m.). Adding a spring enables closure at even lower pressures, at the expense of opening. Emptying the pool: When the level rises, the float ventilates the valve's closing chamber and pressurizes the opening chamber, which causes the valve to fully open even at very low pressures (about 4 m.). When the level drops, the float ventilates the valve's opening chamber and pressurizes the closing chamber, closing the valve even at very low pressures (about 4 m.). Adding a spring enables closure at even lower pressures, at the expense of opening. Broad flow range (see table under Technical Data). Installing a calming device around the float to restrain the wave effect is recommended Installing an external command water filter to protect the float in addition to the existing flushing in-line filter installed in all C-Valves is recommended. Can be operated by hydraulic or electrical remote control. In installations where downstream pressure is low, installing an orifice in the Quikcoup coupling downstream of the valve to maintain a positive valve pressure is recommended. For planning, consult C-Valves' Applications Department. Closure can be restrained. The valve shall be installed in-line and shall be supplied to the installation site accompanied by double - grooved connection pipes to be welded to the line or with Quikcoup flanges. 4. Level (pressure) valve (AV) Maintains a constant pool level. The valve is located in the filling or emptying line. Basic hydraulic double-chambered valve with multi directional ball valve, and level pilot (E). N.C. Valve command is achieved by a high-sensitivity 3-way pilot which maintains constant pressure (level) downstream. No command pipes between the valve and pool are necessary. Filling the pool: When the level drops, the pilot opens the valve to maintain the prescribed pressure, so that the level remains constant (up to 0.4m. deviation). Emptying the pool: When the level rises, the pilot opens the valve to maintain the prescribed pressure, so that the level remains constant (up to 0.4m. deviation). Broad flow range (see table under Technical Data). Installing an external command water filter in addition to the existing flushing in-line filter installed in all C-Valves is recommended. Can be operated by hydraulic or electrical remote control. In installations where downstream pressure is low, installing an orifice in the Quikcoup coupling downstream of the valve to maintain a positive valve pressure is recommended. For planning, consult C-Valves' Applications Department. Closure can be restrained in the event of remote control. The valve shall be installed in-line and shall be supplied to the installation site accompanied by double - grooved connection pipes to be welded to the line or with Quikcoup flanges. 5. Pool valve with electric command (EF) Maintains pool level within the desired range (double level). The valve is located in the filling or emptying line. Basic hydraulic double-chambered valve with multi directional ball valve, and pear float or electrodes. N.C. or N.O. valve. For command, a pear (preferable with substitute contactor) is required, as well as a power source (direct or alternative) and a solenoid adapted to the existing voltage. Filling the pool - N.C. valve: When the level rises, the float disconnects the power supply to the solenoid (N.C.) and the valve closes. When the level drops, the float connects the power supply to the solenoid and the valve closes. Filling the pool - N.O. valve: When the level rises, the float disconnects the power supply to the solenoid (N.O.) and the valve closes. When the level drops, the float connects the power supply to the solenoid and the valve closes. Emptying the pool - N.C. valve: When the level rises, the float connects the power supply to the solenoid (N.C.) and the valve opens. When the level drops, the float disconnects the power supply to the solenoid and the valve closes. Emptying the pool - N.O. valve: When the level rises, the float connects the power supply to the solenoid (N.O.) and the valve opens. When the level drops, the float disconnects the power supply to the solenoid and the valve closes. Broad flow range (see table under Technical Data). Installing a calming device around the pear to restrain the wave effect is recommended. Installing an external command water filter in addition to the existing flushing in-line filter installed in all C-Valves is recommended. Can be operated by hydraulic or electrical remote control. In installations where downstream pressure is low, installing an orifice in the Quikcoup coupling downstream of the valve to maintain a positive valve pressure is recommended. For planning, consult C-Valves' Applications Department. Closure can be restrained. The valve shall be installed in-line and shall be supplied to the installation site accompanied by double - grooved connection pipes to be welded to the line or with Quikcoup flanges.
