Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?
Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
Ordinary ball valve is the reverse turn off, the general ball valve without direction requirements. Each kind has the direction request, generally has the arrow or the nameplate explanation on the valve body.
