Technical Data Principle of Operation 3 Way Control The control device is used to either admit pressure into the control chamber to close the valve, or to relief pressure to the atmosphere to allow the valve to open. 2 Way Electric-Control A solenoid operator plugs the control chamber s outlet. A permanent connection from the upstream through a labyrinth restriction ensures line pressure into the chamber closing the valve. Energizing the solenoid operator opens a drain to the downstream, allowing the valve to open.

Typical Applications DSF Series Valve Types Available M Manually Controlled Valve The valve is controlled manually, by a plastic internal bleed lever (* only in 1 ) or brass 3-port selector, that allows the user to select ON-OFF (* only in 1 ) or the CLOSED / OPEN / AUTO (remote controlled) position of the valve. The control is effortless and quick, even under high pressure conditions. ED2 2-way Electric Valve Electrically actuated, Normally-CLOSED valve with integral solenoid operator. The valve is designed for maximum simplicity for greenhouse and field irrigation, controlled by an electronic controller. Can be supplied with operation using AC, DC, Pulse-DC-Latching or integral 2Wire decoder (DIAS). Manual override is enabled through an integral switch. < Only with a 2-way 24VAC N.C. solenoid or built-in decoder (DIAS) > EL(D3) 3-way Electric Valve A 3-way solenoid valve, activated by electric current or an electric pulse (latch), or a built-in decoder, opens or closes the main valve. The standard valve is supplied as Normally CLOSED ( Normally OPEN is optional). Electric actuation can be added to other control applications on request. < Only with a 3-way 24VAC N.O. solenoid or built-in decoder (DIAS) > < With both 3-way 24VAC N.O. solenoid or built-in decoder (DIAS), and brass 3-port selector > PR Pressure Reducing Valve The valve maintains a preset downstream pressure, regardless of upstream pressure or flow rate fluctuation. The valve allows full opening when upstream pressure drops below the pressure set-point. EL/PR Electrically-activated Pressure Reducing Valve Designed to open and regulate downstream pressure to a stable preset value upon electric command from an irrigation controller. Electric command may be of constant current or pulse, as determined by the controller in use. < Above 5 Photos from the Left to Right side: EL/PR Valves - 1.5 (NYLON), 2 (NYLON), 3 (NYLON), 3 (UPVC), 4 (UPVC) With not only 3-way 24VAC Normally-OPEN solenoid operator, but also pressure regulator and brass 3-port selector >
Instructions EL/PR Electrically-activated Pressure Reducing Valves Please refer to following instructions, about how to operate Electrically-activated Pressure Reducing Valves. 1. Always set the Black Plastic Handle of Brass 3-port Selector to "AUTO" position, imprinted on its Orange Plastic Circular Ring; 2. Connect 2 External Lead Wires of 3-way 24VAC Normally-OPEN Solenoid "3W-R-NO 24VAC" with electricity to energize it, then our EL/PR valves will be opened automatically; 3. If power shortage even without electricity, you can still open EL/PR valves manually, by turn 180 the White Plastic Manual Override Switch of 3-way Black Plastic Base factory-installed with solenoid, to be Upside Down; 4. The Pressure Regulator built inside a Black Plastic Shell attached to EL/PR valves edge, is designed to regulate EL/PR valves downstream / outlet pressure to a stable preset value: 2 bar (Default Setting upon delivery out of our factory); That means: our EL/PR valves maintain the above preset downstream pressure, regardless of upstream pressure or flow rate fluctuation; Our EL/PR valves allow full opening, when upstream pressure drops below the pressure set-point; Anyway, you can still adjust our EL/PR valves outlet pressure up to Another HIGHER Value than 2 bar default setting, by using a wrench to turn CLOCKWISE (recommended in 90 = 1/4 turn step by step), the Hexagonal Stainless-steel Bolt (along with 1/8 Male Threaded Stem) on their Pressure Regulators Top. < * Please make sure: EL/PR valves inlet / upstream pressure should always be HIGHER than their outlet / downstream pressure! > 5. But if you set the Black Plastic Handle of Brass 3-port Selector to "OPEN" or "CLOSE" position, in that case, 3-way 24VAC Normally-OPEN Solenoid "3W-R-NO 24VAC" will be OUT Of Operation - Useless, and our EL/PR valves can also be opened or closed MANUALLY. 6. Regarding Built-in 2Wire Decoder (DIAS): All electric current operated (including EL/PR) valves can instead have a 2 Wire decoder/solenoid (DIAS). These need just a common 2 conductor path to all valves. There are many controllers and interfaces which can operate these, please inquire of Tonick Watering for more detailed information. 7.
