Installation

The valve can be installed vertically or horizontally, but not turned upside down.

- A 3-way valve cannot be transformed into a 2-way valve and vice versa.

- The flow is from A to B (see diagram below) and must be installed so the paddle

closes against the direction of flow as indicated in the following diagrams.

- The 2-way valves can be installed on the

supply or on the return; for correct

installation it is necessary to respect the

direction of flow indicated from the arrow

on the body valve.
