Note: The "A" side of the ball valve should always be on the same side as the coil.
Allows evaporator coil to be isolated without over pressurizing due to warm up. May also have needs in
loop piping and at the rack.
This symbol indicates the direction of pressure relief and direction of check valve feature. Flow
from left to right is check direction. Flow from right to left is pressure relief direction.

- Page 2 Page 2 EN: IMPORTANT This valve has a pressure relief feature in one direction only. If installed incor- rectly, pressures may drastically increase causing rupture of valve, piping and/or other components exposed to such pressure. This could cause dam- age to equipment and cause injury or possible death to anyone in the area. FR: IMPORTANT Cette vanne possède une seule direction de décharge de pression.
