They require a much higher pressure than the output side of the valve to open the valve from either end. Because of this, the valves are used primarily in the control of hydraulic systems. The valves work by closing and opening depending on the current (and expected) fluid pressure. The close-close mechanism is achieved by opening the flange pipe fitting to the right or left and allowing the flow into the flange.<br><br><br>There are four main types of check valve available in the marketplace: spring, diaphragm, wedge, and ball. Spring mechanism uses coils spring installed inside a diaphragm. It is usually found in pressure relief tubes. This type has very limited pressure control capability. The diaphragm forces the piston to move upward or downward depending on its bore diameter and seat depth. At the seat, the diaphragm is fixed and the piston rises or lowers.<br><br><br>The wedge-like check valve, on the other hand, has no standard body design. Therefore, manufacturers can choose from a wide variety of styles, each meeting different performance and efficiency criteria. These valves are typically manufactured using an externally threaded connection, but internal threaded connections may also be used if cost is a limitation. The ball valve has a standard body design. The interior of the ball valve has a number of holes drilled for adjustable air passage through the interior, as well as a seal installed on the top.<br><br><br>In order to properly understand the operation of a check valve, it is important to first understand how they function. The check valve works by closing off an inlet valve on one end (the external threaded connection) while allowing a flow of fluid from an opposite inlet (the internally threaded connection). A spring connected to one end of the externally threaded connection holds the other end of this flow. As the volume of fluid flowing into the outlet increases, the spring gradually grows and expands, thereby releasing the pressure created by the pressure differential. This is similar to the operation of a tire's inflation pressure gauge.<br><br><br>Check valves can have one of several standard designs, including: Upright, Above-Floor, Downstream, and Swing. The above-floor and swing check valves are placed above the floor and upstream of the pump motor; the former is intended for low water conditions; the latter is designed for high water conditions. For high upstream pressure, check valves can be placed in the inlet or the downstream position. Standard check valves have an external seat, an internal seat, and a control device, while some of the more advanced models have additional features such as a separate seat, electronic control, water level indicators, pressure monitoring, and valve remote controls.<br><br><br>The disc-type check valve refers to a single-piece ball valve with an inlet pipe that attaches directly to a source of pressurized water.

Because the ball moves within the inner chamber of the cylinder, the pressure inside the inner cylinder is controlled by the ball. Some check valves have ball and seat features, while others have both features. The disc type is most commonly used in residential applications because it can be mounted on any wall and does not require complex installation procedures. To ensure that high pressure is maintained at all times, this type of valve must be kept in its flange position.<br>
