7 Easy Ways To Make manifold valves in safe

To Installing manifold valves is indeed mechanical to experienced irrigation contractors that when asked to explain the installation steps in-depth, they indubitably will leave out something. In Prep, buy the number of valves per number of zones known for on the job. Other items required are flap boxes, approved waterproof cable connectors, little stone, Teflon tape and PVC cement or springs, which is dependent upon the type of pipe used at work. Establish The general areas where the valves will be placed to determine how many valve boxes will need to be bought. If there are two or three zones close to the primary water supply, a manifold is built, and the valves have been placed together in a master or effluent valve box. The remaining valves are installed with one valve per valve box.

Mark the Place in which the valves must be buried. Position them in inconspicuous areas, such as shrub beds, if at all possible, with the valve being near the primary water connection. Place remaining valves in line with the particular areas of  KP-LOK tubing valves and fittings the property each zone will irrigate. Do not compromise accessibility, and continuously indicate on a drawing in which the valve boxes are buried, for future reference.

“You want “Working on sprinkler heads or the controller is as simple as repairing or replacing a manifold valve. The first step is to select carefully when searching for valves and be certain you’ve got a fantastic, excellent valve — the ideal product for the job.”¬†Bury the Valve box to grade, placing two to four inches of rock in the base of the hole. Situate the valve box in addition to the stone, with no rock extending to the box. The valve will probably be above the stone, which provides for ample drainage. When running the supply line pipe, run the multi-strand cable at the same moment.

“Each Contractor has, at one time in his lifetime, installed a minimum of one valve backward,” explained Carowitz, “The valve normally will not open, and when enough pressure is applied, it might cause damage to the inner parts.” Tape on the threaded connections and PVC sealant for PVC connections. If you choose a shortcut here, you’re going to be back later, digging this valve up and fixing a leak.

“Always Use Teflon tape,” Paul Cordura, president of HIT Products, Inc., urges. “Pipe dope utilized for this purpose will get in the valve and clog up the vents. If you are using valves with slip connections rather than threaded connections and use PVC sealant, make these glue connections over the ground, and place the valve with an angle so the extra glue will run away in the valve. If the adhesive runs into the valve, it is going to get about the diaphragm, and the valve will not open. Make certain that the glue is dry on one side before gluing the second side,” Cordua worries. Attach Another two-and-one-half-inch nipple to another side of the valve, connecting one more elbow as was done on the former side, and a riser going down, just barely under the rocks. Connect an elbow to the end of the riser that’ll be combined with the sprinkler lines

“Just as a Cook who cleans up as he moves together ends using a clean kitchen, the contractor who cleans up as he moves together ends up using a clean setup,” states Cordura. “Think about this valve as you’d the carburetor of an automobile. You wouldn’t pour gas which was sitting in a filthy five-gallon bucket in your vehicle’s gas tank; it might clog the carburetor or fuel injection system.

If more Than one valve is moving to a valve box, it’s much simpler to create a manifold until it goes into the ground. Attach the nipples to either side of all valves being set up. Using an adapter, fasten a piece of pipe between each valve, making sure it’s long enough to cut the valve out afterward if needed. Depending on the number of valves and also the positioning of the distribution line pipe, elbows are using to design the manifold, so it is going to match from the master valve box.

“Pick Valves with captive components, so if you ever need to work on the valve, the components will not float away if disassembling,” says Cook. He agrees with all Carowitz that quality valves will endure for decades in the ground if installed correctly.

Manifold Valves demand 24 volts to operate. Eighteen-gauge multi-colored, multi-strand jacketed wire is utilized to coordinate valve zones with controller stations. The number of strands of cable is dependent on the number of zones being set up; it is recommended that a bigger count wire is put into cover zones which might have to be inserted later.

“Each System I set up is color-coded the same style,” states Danny Wilson, crew chief of Moneta Farm Service, Inc., Irrigation Department, Moneta, Virginia. “I start with the valve in line and that is zone one about the control. It’s wired to the red strand. Zone two is green; three is shameful and so on. The white strand is always the ground wire. While I have to support a valve and it’s wired with all the green, I understand two. It is just a simple system that I use.”

Publish a Secure the wire splices having an approved waterproof wire nut encased in dirt, DBY or dry splice product. Do not have a shortcut on this step either. “Manifold Tape, dipping the splice in PVC cement or some other quick fix to save fifty cents isn’t worth the trouble it will cause,” Carowitz states. “Moisture will get in the connection, causing corrosion. This will cause a brief or worse, making a nightmare to repair. If you take some time to fix it right, the connection should last for decades.”

After all of the valves are wired, then run the multi-strand cable in conduit from The valve to the control. Wire the colored wire to the corresponding channel on the control, and the standard wire to the floor or common terminal on the control.

Following the valves have been installed and connected to the control, Shut the flow control and manual bleed screws on the valves. If there If some heads are fogging in the nozzle, then reduce the flow before the fogging ceases. Close to the manual bleed screws then shut off the water and turn the machine back with the control. Allow the system run through an entire cycle.

If each Zone turns on, you have correctly set up the manifold valves. Up until a few decades ago, valve boxes were available in a variety of sizes, but only in black with green grasses. Today, the manufacturers are becoming “fashion conscious” and therefore are offering valve or accessibility boxes in colors to coordinate with the landscape. With this Follow all The steps, and avoid taking shortcuts.
