What is the difference between the drizzle valve installed in front of the valve and the one installed behind the valve? ? There are cut-off valves before and after the regulating valve. The diversion valve can drain out the medium inside whether it is installed at the front or at the back. Why is it required to be installed in front of the valve?

If it is a stop valve, if the diversion valve is installed behind the valve, it will definitely not be drained cleanly. If it can be installed at the front and back, you can install it at the front.
It is generally installed in front of the regulating valve. If a warm pipe is required, it should be discharged in front of the valve.； In addition, if it leaks after it is installed on the valve, the adjustment will not be linear.
