Refit the sprinkler heads and screw them down fully then fill back the channel, levelling the surface with the ground surface (and with the top edge of the pop-up sprinklers). 90896 - programmable solenoid valve 3/4” m; 90829 - hydro 4; 90839 - hydro 4 rf; other. The diagrams below provide sprinkler positioning examples; bear in mind that: Pay attention to the PRESSURE DROP in the tubes: this table shows the values to be subtracted from the static pressure available upline. Insert a stake at each point at which a sprinkler is to be fitted. Make sure the water consumption of each zone is no higher than the available flow rate. Place the tee connectors, couplings and drainage valves on the ground at the points where they are to be installed. Referring to the sprinkler performance data table, mark the water consumption in litres per minute alongside each sprinkler on the layout diagram. 90813. Place the circuit tube in the channel, making sure the sprinklers are perfectly flush with the ground surface (you are aided in this by the threaded extension element supporting the sprinklers, which features cut-off segments to adjust the sprinkler height). Resulting from Claber research and experience, a highly technological, 100% reliable solenoid valve. Take pressure readings at different times of the day and night, when the water supply pressure is generally higher. Unwind the polyethylene tube from the valves up to the sprinkler stakes, along the marked circuit path. You’ll need a compass to draw the circumferences of the circles or segments served by each sprinkler until you have covered the entire area. Resulting from Claber research and experience, a highly technological, 100% reliable solenoid valve. Now it’s time to connect all the pre-cut tube lengths to all the sprinklers and the drainage valve,as required in the layout. The solenoid valves unit contains the individual valves required to open and close each circuit. To ensure efficient operation, conventional underground irrigation systems based on a Ø25mm – Ø32mm PE pipe and pop-up or turbine sprinklers need a supply of water that will guarantee a minimum flow rate of 25-30 l/min at a pressure of no less than 3 bar. The solenoid valves unit contains the individual valves required to open and close each circuit.The supply line to which the valves are connected is subject to the entire static pressure (when the circuit is closed) and it must therefore be composed of an absolutely water-tight metal pipe.As a general rule the diameter of the pipe used to connect the valves unit to the utility line should be no smaller than the diameter of the valves. the practicality of being able to water your garden automatically, even when you’re away or on holiday, with no need to find a kindly neighbour or friend to do the job; the certainty that each area of the garden will receive exactly the water it needs, without waste and with economical running costs; complete absence of above-ground tubes, which can constitute an obstruction for a lawnmower: even the sprinklers are perfectly flush with the ground surface and are barely visible at a glance; noiseless operation, so no risk of disturbing your neighbours; an increase in the value of your home; on the modern housing market a well-kept garden with an automatic watering system is a definite bonus. prepare a tank of capacity equal to or greater than that which would be sufficient to water the entire garden at any one time; connect the tank to a supply of water (e.g. When the circuit is closed and there is no flow, the drainage valve opens automatically to drain off any water left in the system, which might otherwise freeze and damage the tubes. For better results install 90° sprinklers at the corners of the area to be watered, 180° sprinklers along the borders and 360° sprinklers in the open spaces. Remove the head from each sprinkler by simply unscrewing it: after opening the valves the flow of water will flush out the circuit. Carefully straighten out the tube required before cutting it to length (leave some excess). Solenoid valves. Now group together the sprinklers in different zones (use different colour pens) adding together the water consumption of each one progressively. The DYNAMIC pressure must be such as to allow the sprinklers to function as they are designed. Claber has looked carefully at the features of modern green spaces and the needs of gardening and horticulture enthusiasts, and come up with a brand new solution: HYDRO-4. The water flow rate can be measured easily using a container of known volume and checking the time required to fill it.For example, if a 10 litre container can be filled in 20 seconds, the flow rate is 30 litres per minute. 90° sprinklers should be positioned at the corners of the garden; 180° sprinklers should be positioned along the sides of the garden; adjustable sprinklers should be used for angles or 270° or irregular angles; 360° sprinklers should be used for any central areas that are not yet covered. As we can see in the examples, the circumferences of each watered area will overlap to ensure complete coverage of the surface area and perfusion of a uniform water quantity at all points. 9 V - 1” (26 - 34 mm) Male solenoid valve wiyhout faston. Your irrigation system is now complete and ready to perform the watering cycles set on the automatic timer. Supplying the UK's garden professionals with the best brands, at the best prices since 2000. It’s also important to install a gate valve on the main pipe upline from the circuit solenoid valves to shut off the entire system whenever necessary, such as for maintenance work. Made with resistant, perfectly watertight materials, tested at the highest pressures for domestic applications (up to 12 bar), but ideal even for lower pressures, it is equipped with a filter that traps any impurities in the water, expelling them from the irrigation circuit the next time it is started up. You’ll reap a host of benefits if you choose to install an underground automatic irrigation system: BEWARE OF THE COLD In areas subject to frost, a drainage valve must be installed at the lowest point on each distribution line. Claber Mains Solenoid Valves - 24v. Starting from the point at which the solenoid valves will be installed to control each circuit, plot the connecting path of each valve to the corresponding sprinklers grouped together in zones, thereby obtaining independently controlled circuits. 8538 - ERGO SPRAY PISTOL; 8540-8541 - SHOWER JET PISTOL ERGO If your water supply does not match these parameters you have three options: Fit a pressure gauge on an outdoor tap and open the tap completely while ensuring that all other taps in the house are off (STATIC pressure). Using a spade, dig out a channel to a depth of at least 20-25 cm: this should prove fairly easy, and it means the system will be sufficiently protected from winter frost.To protect the lawn surface it is good practice to lay out a plastic sheet on which to heap the excess soil from the channel. When the water supply is turned on again the drainage valve closes automatically. 90812 - 90822 - SOLENOID VALVE 9V 1” F. Nozzles and pistols. You can borrow or hire a pressure gauge from a plumber. Use string or chalk powder to mark out the tubes path of each circuit, from the solenoid valve to the associated group of sprinklers. Try to create a balanced system: each circuit should have the same water consumption. Consider installing an above-ground system. Get out into the garden and transform your plan into a fully functional irrigation system. 90814. main, rainwater barrel); install a pump (underground or surface) of rated power between 1 and 1.5 HP and head not less than 35-40 m, capable of delivering a flow rate proportionate to the amount of water the connected sprinklers are expected to consume. Once you have fixed the sprinklers in a vertical position (tying them to the stakes with string) test operation of the circuit and make any position changes required to ensure perfect coverage.When you finish the job, it’s good practice to flush the circuit to eliminate any debris that may have entered during the installation procedures. Once all the circuits have been prepared on the ground and the required irrigation output has been obtained, it’s time to bury the tubes in the ground. Cut the tube with a hacksaw and use a scraper to clean the edges to remove any trace of shavings and burr before fitting the compression connectors (this ensures a perfectly water-tight seal). 90812. 24V - 1” (26 - 34 mm) Male solenoid valve without faston.

Website by, Battery Powered Controllers, Manifolds & Valves, Mains Powered Controllers, Manifolds & Valves, Solenoid Cable, Manifold Filters & Accessories, Light Symphony Signal Repeaters & Sensors. Solenoid valves 24 Volt; 24V - 1” (26 - 34 mm) Female solenoid valve without faston. Now place the required sprinkler for each position on the ground beside each stake together with the threaded bracket coupling designed to hold the threaded extension (before fitting the extension remember that you need to drill a hole in the tube with a 10 mm bit). Once you’ve connected the solenoid valves to the water utility pipe, take the layout drawing and mark out the path of the tubes in each sprinkler circuit. The supply line to which the valves are connected is subject to the entire static pressure (when the circuit is closed) and it must therefore be composed of an absolutely water-tight metal pipe. Since you have to create a channel in which to bury the polyethylene tube, it is advisable to plot straight lines, avoiding paths, terraces and other obstacles that will be hard to cross when actually installing the tube.
