Q. Who founded Watts?

A. Joseph Watts founded the company 'Watts Water Technology' in 1874 with the hope that water boilers in textile industries should not explode.

Q. Can a pressure relief valve be installed upside down?

A. A pressure relief valve can be mounted upside down, however, the best way to install a pressure relief valve is in a vertical position, which means the spindle should be vertical and the valve should be in an upright position.

Q. What is the difference between a flow regulator and a pressure regulator?

A. Flow control valves are used for controlling and adjusting fluid or gas flow through a system. On the other hand, pressure control valves are used to regulate the pressure of a fluid passing through a pipe.
