Installation for DN40-50
IMPORTANT: Hold valve with a pipe wrench by hexagonal fitting ONLY. Do NOT handle the valve body with the pipe
wrench; product damage may result.
Refer VPI series PICV Product Datasheets for more details on valve and actuator dimensions.
The procedure to install DN 40-50 valve is as follows:
1. Clean the lines upstream of particles larger than 1/16 in. diameter (welding slag, pipe scale and other
contaminants) to properly flush the system.
2. Proceed with installation once the system specifics (expansion/contraction of the system and its medium as well
as operating pressures) are within tolerances.
3. Eliminate air from the system.
4. See Figure 6 to familiarize yourself with the valve and its components. The Valve Body (A) is the housing marked
with an arrow to show flow direction. The Flow Regulator (B) which is fixed with valve body, regulates flow.
IMPORTANT: Do not disassemble or attempt to remove the Flow regulator from the valve body. Doing so may
damage the valve and will void warranty.
Pressure ports (C) facilitates user to gauge pressure across ends. The Plugs (D) comes with valve models without
pressure ports. See VPI series PICV Product Datasheets for more details on models with and without pressure
ports.

IMPORTANT: Flow arrows must point in the direction of the flow for proper operation.
5. Install the valve housing with the flow directional arrow pointing in the correct direction.
6. For threaded connections please clear threads on both valve and piping of debris. Honeywell recommends thread
or pipe sealant (Permabond A1044 or equivalent). When using Teflon tape, it is recommended to use 4-6 rounds
of tape applied tightly in clockwise rotation. When using hemp as pipe sealant, ensure no strands are left in the
valve or piping.
IMPORTANT: Never use mineral oil or petrol-based grease or oil on the O-rings.
7. Set the desired flow rate by adjusting scale setting of the dial with a special adjustment key.
