4. General Information
The INNOVA Mini N single seat valve is a shut-o valve that is used to open or close sections of a
pipe. The INNOVA Mini K single seat valve is a divert valve to divert the product with a converging
ow.
Because these two types of valve are single seat valve, they only have one union that separates
the two lines of the pipe. This means that they are not suitable for separating incompatible products,
since if there is a failure in the union if may not be detected and the products could mix.
4.1. DESCRIPTION
4.2. APPLICATION
The INNOVA Mini N and INNOVA Mini K single seat valve are a sanitary and exible design for a
wide range of applications in the food, pharmaceutical, chemical and beverage industries.
The INNOVA Mini N valve is usually used for emptying, drainage or as a shut-o valve on a bypass
line.
The INNOVA Mini K valve is often used to supply CIP and on return lines.

5.4. LOCATION
Place the valve leaving enough space around it to realize easily the dismantling, the inspection and
the review the valve as well as in order to access to the actuator air connection’s device for valves
with automatic actuation even when the valve is operating. Consult in chapter 5.8. Welding the re-
quired minimum distances. The installation should allow that the removable parts are could remove
easily.
5.5. GENERAL INSTALLATION
After the location of the valve is dened, the valve can be joined to the pipe by welding the valve
housing or using ttings.
In case of joining the valve to the pipe by ttings do not forget the seals and tighten the unions pro-
perly.
If instead, the valve is joined by welding, before starting to weld the valve bodies to the pipe disas-
semble the valve to prevent damage to the joints, following the instructions in chapter 8.4. Disas-
sembly and assembly the valve.
During installation, the valve avoids using excessive force and pay special attention to:
- vibrations that may be produced on the facility,
- thermal dilation that the pipe may undergo when hot uids are circulating,
- the weight that the pipe can support,
- excessive welding current.
The connections must be EHEDG-approved as described in EHEDG Position Paper (see www.
ehedg.org/guidelines).
5.6. DIRECTION OF FLOW
The following image indicates the recommended direction for product ow, as well as the direction of
closing, depending on the type of valve. 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 uid.

8.5. REPLACING THE SEAT SEAL
1. Put the plug shaft in a vertical position –for example, with
a bench clamp- so that the shaft is kept stable and no da-
mage is caused to the mating surface of the conical seal.
Do not press the shaft too much if using a bench clamp.
2. Remove the used seal using a screw driver or a sharp
hook-shaped tool. Make sure not to damage the mating
surface of the seal.
3. Lubricate the new seat seal with soapy water if neces-
sary to facilitate installation.
4. Insert the seal in the plug shaft seat accommodation so
that its edges are inside the accommodation. Preferably,
the seal should t within the part of the section that has the
greatest diameter, as shown in the gure.
5. Then, with the help of an appropriate tool (not piercing),
press the edge of the seal that has not yet t into the ac-
commodation, as shown in the gure.
6. This operation should be done around the entire diame-
ter, applying the tool in the sequence 1-2-3-4-5-6-7-8 as
shown in the bottom gure. Always press on opposite si-
des. Once you get to the last step of this sequence, repeat
the process until the seal is completely inside the accom-
modation.
7. Press the seal with your ngers to make sure it is well
seated. Make sure there are no parts projecting due to the
poor positioning of the seal.
