5.4. LOCATION
The valve should be installed in a manner that permits to be cleaned, inspected and self-draining. Allow
sufficient spacer around the valve for adequate review, dismantling and maintenance. See table in section 5.8.
Welding.
Installation shall allow that removable parts shall be readily disassembled.
5.5. DIRECTION OF FLOW
The following image indicates the recommended direction for product flow, as well as the direction of closing.
Following these indications will prevent water hammer and its consequences to the extent possible, which can
occur when valves close.
The recommended direction will always be contrary to the movement of valve closing, that is, when the valve is
closing, the valve will always work against the pressure of the fluid.
5.6. GENERAL INSTALLATION
After the location of the valve is defined, the pipe can be joined by welding the valve body or using fittings. In
this case, do not forget the seals, and tighten the unions properly.
Before starting to weld the valve bodies to the pipe, disassemble the valve to prevent damage to the joints,
following the instructions in section 8.4. Assembly and disassembly of the valve.
Avoid using excessive force when assembling the valves, and pay special attention to:
vibrations that may be produced on the facility,
thermal dilation that the pipe may undergo when hot fluids are circulating,
the weight that the pipe can support,
excessive welding current.

1. Loosen the 4 bolts (32) and remove the cap (39).
2. Remove the air fitting (18A).
3. Situate the actuator in the base of the clamp or in the lathe
collet. A thick tube (102) and a shim (101) must be used
on the free end of the actuator.
4. Apply force to the shim. Once the cover (12) has dropped
15 –20 mm, remove the snap ring (45). This should have
sufficient free space to be able to remove it.
5. Reduce the force on the shim slowly until the top cover is
free (you will note that the spring no longer exerts
pressure).
6. Remove the cover (12) and the internal components,
spring assembly (06) and piston (30).
7. Take out the seals (20A and 20B), the scraper (60) and
the guide (11) from the cover (12).
8. Take out the seals (20 and 20C) from the piston (30).
9. Dismount the scraper (60), seal (20B) and guide (11) from
the base of the actuator.
8.6.2. Assembly
1. Mount the scraper (60), seal (20B) and guide (11) on the
base of the actuator.
2. Mount the seals (20A and 20B), the scraper (60) and the
guide (11) for the cover (12).
3. Put the seals (20 and 20C) on the piston (30).
4. Put the piston (30) and the spring assembly (06) inside the
cylinder (01).
5. Mount the top cover (12) on the cylinder.
6. Apply force to the shim so it lowers 15 –20 mm. Insert the
snap ring (45).
7. Reduce the force applied slowly until the tool no longer
touches the cover.
8. Install the counter cover (3) and screw in the 4 bolts (32).
9. Install air fitting (18A).
10. Apply compressed air to check the proper functioning of
the actuator
