How Do I Shut Off the Water!!!? Types of Water Valves. There are currently two types of water valves used to turn on or turn off the water flow to your house: the gate valve and the ball valve. More traditional and reliable, the gate valve is a round or oval handle that needs to be turned counter-clockwise to stop all water flow.

Engineering Essentials: Pressure-Control Valves Pressure-control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit. Types include relief, reducing, sequence, counterbalance, and unloading. All of these are normally closed valves, except for reducing valves, which are normally open. For most of these valves, a restriction is necessary to produce the required pressure control. One exception is the externally piloted unloading valve, which depends on an external signal for its actuation.

How To Close A Water Main Shut Off Valve â Choosing The Correct Valve To Close The NYC DEP code requires ball valves to be full-port opening valves, which do not restrict the flow of water into the property. Saving a dollar or two on a ball valve that restricts the flow of water makes no sense when considering which shut off valve to install as the main valve.

Plumbing Valve Basics Ball valve. Ball valves use a stainless steel ball to control water flow. There are three basic valve styles, making this a classic case of good, better and best (described in order as follows). All three can be used for water, oil or airflow control if the casting has WOG stamped on it.t's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.

Installing a Pressure or Flow Switch to Protect your Irrigation System A master valve is a single valve located at the water source that can shut off all the flow of water into the irrigation system. For more details see my article on master valves. On systems with a pump you will probably want to shut off the pump.. Make sure you have a really good quality spring-loaded check valve on the irrigation mainline pipe. The check valve goes someplace after the pump, but before the pressure switch. A good quality check valve is needed to keep the water from leaking backwards out of the system through the pump.

- A check valve is a valve that allows liquids or gases in a pipeline to flow in one direction but closes to prevent flow in the opposite direction. These types of valves are used extensively in the pipeline industry to prevent reverse-flow or back-flow in the event of a pipeline leak or abnormal operating occurrence.

- Ball Valves. The small shutoff valves you find under sinks and toilets are often ball valves. The valve chamber contains a close-fitting plastic or metal ball with a hole in it, and it's closed when the hole is aligned perpendicular to the water flow. The operation of a ball-valve differs from either a gate or stop valve because you can only turn the handle through 90 degrees. The valve is open when the lever is parallel to the water flow and closed when it's perpendicular.

- Even if the supply water pressure fluctuates, the pressure reducing valve ensures a constant flow of water at a functional pressure, as long as the supply pressure does not drop below the valve's pre-set pressure.ost plumbing codes require water pressure reducing valves on domestic systems where the municipal water main's pressure exceeds 80psi. Higher pressures could rupture pipes, damage fixtures,and injure the people using them.
