Components of the Watts 800m4
The Watts 800m4 is a pressure vacuum breaker (PVB) that is designed to protect the potable water supply from contamination. It is commonly used in irrigation systems and other applications where backflow prevention is necessary. The 800m4 consists of several key components that work together to ensure the proper functioning of the device.
One of the main components of the Watts 800m4 is the inlet and outlet assembly. This assembly is responsible for allowing water to enter and exit the PVB. It includes an inlet check valve that allows water to flow into the device, as well as an outlet check valve that prevents water from flowing back into the potable water supply. The inlet and outlet assembly also includes a pressure differential relief valve, which is designed to relieve excess pressure in the system.
- The second important component of the Watts 800m4 is the air inlet float assembly. This assembly is located at the top of the device and is responsible for allowing air to enter the PVB in order to prevent siphoning. It consists of a float assembly that rises and falls with changes in water level, as well as an air inlet valve that opens and closes to allow air into the system.
- The third component of the 800m4 is the check valve body. This is the main body of the device and houses the internal components. It includes a spring-loaded check valve that prevents water from flowing back into the potable water supply, as well as a seat ring that provides a seal for the check valve.
- The fourth component of the Watts 800m4 is the diaphragm assembly. This assembly is responsible for regulating the flow of water through the device. It consists of a rubber diaphragm that moves up and down in response to changes in water pressure, as well as a disc that controls the flow of water through the assembly.
The Watts 800m4 is an essential component in many irrigation systems and other applications where backflow prevention is necessary. Its various components work together to ensure the proper functioning of the device and protect the potable water supply from contamination. Understanding the different components of the 800m4 can help in troubleshooting and maintaining the device for optimal performance.
How does the Watts 800m4 work?
The Watts 800m4 is a pressure vacuum breaker assembly (PVB) that is designed to protect the water supply against backflow. It is commonly used in irrigation systems and industrial applications where there is a risk of contaminants being siphoned back into the water supply.
The PVB works by using a spring-loaded check valve and an air inlet valve to prevent the reverse flow of water. The spring-loaded check valve allows water to flow in one direction, but closes to prevent backflow. This ensures that water can only flow out of the assembly and cannot be siphoned back into the water supply.
When the pressure in the system drops below atmospheric pressure, the air inlet valve opens, allowing air to enter the PVB. This creates a barrier of air that prevents water from being siphoned back into the system. The air inlet valve is equipped with a vent that allows any trapped air to escape, ensuring the PVB functions properly.
The Watts 800m4 also incorporates a test cock and two shutoff valves for easy maintenance and testing. The test cock allows for the testing of the PVB’s functionality, and the shutoff valves can be used to isolate the PVB for repairs or replacement.
Overall, the Watts 800m4 is a reliable and effective device for preventing backflow in water supply systems. Its design and features make it easy to maintain and test, ensuring that the water supply remains safe and free from contaminants.
