Installation
CAUTION: When installing the valve, ensure that no
foreign materials (e.g. tools, screws, welding wire,
lubricants, cloths, etc.) are enclosed in the system.
Location
The valve must be in a vertical position to ensure that the vent/
drain outlet system functions properly.
The vent/drain outlet at the bottom of the Mix Proof valve must
not be obstructed. The unrestricted vent/drain outlet must allow
leakages and cleaning/rinsing/sterilization fluids to go to atmo-
sphere in order to guarantee mix pr
oof safe separation. If hoses,
pipes, or other components are mounted to the vent/drain outlet
to prevent splashing of leakage and cleaning/rinsing/sterilization
fluids, then they must be designed such that the fluids flow freely
to atmosphere.
CAUTION:
Isolate products away
from the valve prior to performing
maintenance.
Locate the valve for easy access for inspection.
Ensure that the valves and pipe systems drain properly. The two-
piece body option enables the positions of the connections to be
adjusted in relation to each other.
Welding Instructions
Figure 1 - Valve orientation
Prior to installing, thoroughly inspect each valve. When using but-
tweld two-piece body valves, clamp connections must be used on
either the upper or lower body to allow for servicing of the o-ring
seal between the bodies. This does not apply single-piece bod-
ies.
Mix Proof valves with welded connecti
ons require the following to
be performed before installation:
• Prior to installation, remove the stem actuator assembly and
lower bearing carrier.
• Remove all seals from the body.
• Weld the body into position, ensuring that the connection is
free of tension and distortion.
NOTE: Orient the valve so that the "UP" inscription (near the
adapter-to-body connection) is pointed toward the actuator. See
Figure 1.
CAUTION:
Welding must be carried out by qualified
personnel.
For manifold welding, fixture tables are recommended. Matrix
manifold welding requires a controlled deliberate process to
maintain the alignment of the parts.
Air Supply
Install the valves using dry, filtered air. Lubrication is not required.
If using lubricated air, refer to the solenoid manufacturer’s specifi-
cations. The air supply must be 75 to 100 psi (5.2 to 6.9 bar).
Flow Direction
The valves should be installed to close against the flow to prevent
hammering.
CAUTION: Before attempting to
buttweld an automatic valve into
a line, disassemble the body
from the actuator. Dissipate
heat away from the valve body
to prevent warping.
