Most Cash Acme water pressure regulators come preset at 45psi but can be adjusted within a specific range depending on the model. As the downstream water pressure approaches the set pressure, the valve will close off, not allowing water to pass through. As that downstream water pressure drops, typically due to water usage, the pressure regulator will open back up letting water through to recharge the system as long as the demand is needed.

•The Double Check Valve Assembly (DCVA) is designed to prevent backflow in a water distribution system where there is a non-health hazard. It features a backflow preventer to stop the reverse flow of liquids caused by backpressure or backsiphonage. The DCVA has a compact vault design which allows for easy installation and maintenance. The single cover, top-entry design provides convenient access for maintenance. DCVAs can be installed in systems under continuous pressure service and may be subject to back pressure. In non-flow conditions, the check valves maintain a minimum of 1 PSI in the direction of flow. In flow conditions, the check valves open proportionally to the flow demand. In the event of backflow, the check valves will close until normal flow is resumed.

Double Check ValveBackflow Preventer

A Double Check Valve Assembly (DCVA) is a device that is used to prevent backflow in a water distribution system. It consists of two independent check valves that are connected in series and a testable auxiliary valve. The DCVA works by allowing water to flow in one direction, while preventing it from flowing in the opposite direction. When water flows through the first check valve, it opens and allows the water to pass through. When the water flow stops or reverses, the first check valve closes, preventing the water from flowing back. The second check valve works in the same way, providing an additional layer of protection against backflow. The testable auxiliary valve is used to test the proper functioning of the check valves. It allows the water to flow in the opposite direction to the normal flow for testing purposes. In the event of a backflow condition, such as a sudden increase in the water pressure upstream, both check valves will close and prevent the contaminated water from flowing into the potable water supply. This ensures that the drinking water remains safe and clean. Double Check Valve Assemblies (DCVAs) are available in a wide range of sizes and flow rates to suit different applications. The size and flow rate of a DCVA will depend on the specific requirements of the water distribution system it is being used in. In general, DCVAs are available in pipe sizes ranging from 1/2 inch to 12 inches. The flow rate of a DCVA is measured in gallons per minute (GPM).
