A visit to any brick and mortar store or even an online one will show you exactly how many irrigation valves are on offer. There are manual ones and automatic ones. Square and spherical, they come in all shapes, sizes and specifications. You name the project and there will be a valve for it. The material, cost and the structure will vary not just according to the application but based on your preference as well. Some have unpronounceable names and look very fancy but the mechanism is generally simple and based on a very common operation.

Many marine and agricultural vehicles use griffin filters the ones you use will be dependent on the scale of your project as well. Griffin filters are great for boat applications for removing water and debris from fuels. Filter elements for 500 and 1000 series are available in 2, 10 and 30 microns. Griffin are similar to Racor filters and of equal quality. Many variations exist including glass bowls, stainless steel bowls and heat shielded filters. You should adhere to the application specifications to ensure that maintenance and cost are not affected negatively. Service valves and ...
... Griffin filters can be used in conjunction with each other to provide optimum. It is best to buy these at the same time and the specifications will have to be matched to the “T”.

A service valve performs a very simple and basic function. It either allows or stops the flow of water and it features two different points of connection- One connecting the water supply and the other to the actual irrigation system. Pressing a lever lock or turning a handle opens the water-flow. The inside of the valve has a channel and turning the valve causes the plug, ball or disc to block that particular channel. Another variety is the check valve. This prevents the water in the irrigation system from flowing backward to its origination point. Fluctuations in the pressure of water can lead to a reverse-flow. A check valve cannot be adjusted, nor does it have a handle.

It offers a one-way point to the irrigation section of a system. The inside of the valve has a channel. As the water starts flowing from the supply side to the irrigation side the hinged disc or a ball floats freely inside this channel. If the water tries to push back from the irrigation side, the disc or the ball gets pushed back into position and wedges itself firmly at the mouth of the valve opening, thus preventing a back-flow. A pressure-relief valve is the guard of an irrigation system. It is like a watchdog that guards against any excessive pressure build-up.

Any pressure can damage pipes and change the watering rates and is a malady that affects many irrigation systems in rural areas, which are fed via wells. The spring that the body of the valve holds, is calibrated in such a manner that it responds to the minutest of changes in pressure levels. The spring contracts, opens the valve and then releases a portion of the water. A pressure-reducing valve adjusts the pressure of water that flows through the channel. Any high pressure from the supply side gets regulated and turns into a lower pressure on the irrigation side. In most cases, a mix-and-match of valves will be used in any irrigation system.
