800MC

Introducing our Watts Regulator 800MC 1/2 Pressure Vacuum Breaker Fnob, a vital component for ensuring the proper functioning and safety of your water supply system. This regulator, manufactured by the renowned Watts Water Technologies, is specifically designed to provide reliable pressure regulation and vacuum protection for your plumbing applications.

The Watts Regulator 800MC is a diaphragm-type vacuum breaker, which means it utilizes a flexible diaphragm to separate the suction and pressure sides of the water flow. This design ensures that air is always allowed to enter the system during backflow, preventing the build-up of vacuum pressure that can cause damage or disrupt water service.

The regulator has a maximum capacity of 800 millimeters of water column (MCWC), making it suitable for applications with moderate water pressure. The 1/2 inch thread size allows for easy installation and compatibility with a wide range of water supply systems.

The vacuum breaker features a pressure relief valve that automatically vents excess pressure to the atmosphere when the water flow is interrupted. This valve is designed to open at a pressure of 15 psi (pounds per square inch) and close when the water flow is resumed, ensuring that the system remains pressure balanced.

The Fnob, or foot valve operating nut, is an essential part of the vacuum breaker assembly. It is designed to be easily accessible for adjustments or maintenance. The Fnob can be used to fine-tune the water flow and pressure to meet the specific requirements of your plumbing system.

In summary, the Watts Regulator 800MC 1/2 Pressure Vacuum Breaker Fnob is a high-quality, reliable solution for maintaining proper water pressure and preventing backflow in your plumbing system. Its diaphragm design ensures effective vacuum protection, while the adjustable Fnob allows for fine-tuning of water flow and pressure. With its 800 MCWC capacity and 1/2 inch thread size, this regulator is a versatile choice for a wide range of plumbing applications.
