1. General information
1.1 Introduction
• These instructions apply to series 6X Multiport Ball Val-
ves, also referred to below as fittings.
• Read the instructions completely before using our pro-
ducts to prevent injuries, material damage and mal-
functions!
• Save the instructions for later reference.
• All rights including copyright and industrial property
rights are explicitly reserved.
1.2 Warnings
• Warnings are always identified by a signal word. The
following signal words or hazard levels are used:
Danger: Failure to follow instructions will
lead to serious injuries or death. High risk le-
vel of endangerment.
Warning: Failure to follow instructions may
lead to serious injuries or death. Moderate
risk level of endangerment.
Caution: May lead to slight or moderate inju-
ries. Low risk level of endangerment.
Note: Refers to an instruction that must ab-
solutely be followed.
Information: Gives useful tips and recom-
mendations..
1.3 Special Hazards
• It must be ensured that the fitting is resistant for the
media and temperatures that will be used. The resis-
tance of the fitting with aggressive media depends in
individual cases on many variables (such as the tem-
perature, concentration ratio of the medium, material,
environment, tube material etc.). The person ordering
the fitting is responsible for checking for the specific
application. In case of doubt install the fitting on a trial
basis.
• Always comply with the safety data sheets or the safety
requirements for the media you are using!
• Before removing the fitting it must be ensured that the-
re is no more medium in the flexible tube/pipe system
and the pressure has completely dissipated. Exercise
caution for toxic, corrosive or hot media residue flowing
out of the line or remaining in dead spaces.
1.4 General Safety Instructions
• The fitting must be properly connected to the flexible
tube/pipe system.
• Before installing the fitting make certain that external
mechanical effects such as thrust and bending forces
are not acting on the flexible tube/pipe system.
• Installation, commissioning, operation, installation,
maintenance, troubleshooting and disassembly must
only be performed by qualified specialists with due con-
sideration of accident prevention regulations. Person-
nel must be capable based on their technical training
and experience of performing assembly tasks, follo-
wing technical specifications and recognizing possible
dangers.
• Personnel with deficient knowledge must be trained
and instructed.
• Areas of responsibility and responsibilities must be pre-
cisely regulated and personnel must be monitored.
These safety instructions do not take into consideration
any:
• Coincidences and events that could occur at the cus-
tomer location during assembly, operation and mainte-
nance.
• Local safety requirements, for which the operating
company is responsible to ensure compliance, inclu-
ding assembly personnel who are used.
1.5 Designated Use
• The fitting must only be operated within the permitted
usage ranges for pressure and temperature.
• Only the operating media named in the documentation
are permitted to flow through the fitting.
• The fitting must only be operated if it is in flawless tech-
nical condition.
• The fitting must not be operated if it is in partially as-
sembled condition.
• If other operating modes are not named in the docu-
mentation, they must be approved with the manufac-
turer.
1.6 Reasonably Foreseeable Misuse
• Any usage other than designated use.
• Do not make any modifications to the product by your-
self!
• Components should only be retrofitted after consulta-
tion with the manufacturer.

2 Manufacturer’s Specification
2.1 Description
The multiport ball valves series 6X comprise two multi-
way ball valves, arranged in a compact design on top of
each other in one housing on two levels. There is no flow
connection between the individual levels. During swit-
ching both media flows are synchronously distributed or
collected using a common shaft. The valve is operated by
a pneumatic actuator.
2.2 Transport and Storage
• The fitting must be protected against mechanical da-
mage, moisture, dirt and dust. The storage temperatu-
re range is 10 – 40°C.
• Avoid UV radiation and direct sunlight.
• Leave the fitting in its original packaging to ensure the
best possible protection.
• Dispose of the packaging material according to dispo-
sal requirements/environmental protection regulations.

4 Assembly and Operation
4.1 Assembly Instructions
• Make certain the fitting is suitable for the relevant ap-
plication. The fitting must be suitable for the operating
conditions of the pipeline system (medium, concentra-
tion, temperature and pressure) as well as the relevant
ambient conditions.
• Check the fitting for transport damage before installing
it. If the fitting is damaged do not install it.
• The planner, the construction company or operating
company are responsible for the positioning and instal-
lation of the fitting. Planning and installation errors can
adversely affect the reliable functionality of the fitting
and may represent a significant potential for hazard.
• After the fitting is installed perform a tightness and
function check.
4.2 Tools Required
The tools required for installation and assembly are not
included with delivery.
4.3 Connect Ball Valve
• The fitting must be connected to the pipeline so it is
free of mechanical stress.
• The Ball Valve has a female thread (ISO, DIN,
ANSI) and can be connected with various connecting
elements of the emtechnik system.
Cylindrical thread Conical thread
Sealing is provided by a sealing collar for
Cylindrical threads (G, M or UNF).
A version with an O-ring is also possible.
Sealing is provided by
the thread itself for Co-
nical threads (NPT).
Sealing Collar O-Ring Thread
• Each thread must always be connected with the same
thread type.
• If a plastic fitting is used in combination with a metal-
lic male fitting, additional sealing with Teflon® tape is
recommended.
5 Commissioning
5.1 Precondition for Commissioning
• Protect against leaks: Take protective measures
against exceeding the maximum permitted pressure
due to possible pressure surges.
• Check the tightness and function of the fitting.
• In new systems and after repairs, flush the line system
to remove foreign materials.
5.2 Control Function
Control function 1 (Standard) – Normally closed (NC):
Ball valve resting position: closed by spring force. Activation of the
actuator (connector 2) opens the ball valve. When the actuator is
vented, the ball valve is closed by spring force.
In case of control function 1: connector 1 is closed with a blanking
plug.
Control function 2 – Normally open (NO):
Ball valve resting position: opened by spring force. Activation of the
actuator (connector 2) closes the ball valve. When the actuator is
vented, the ball valve is opened by spring force.
In case of control function 2: connector 1 is closed with a blanking
plug.
Control function 3 – Double acting (DA):
Ball valve resting position: undefined. The valve is opened and closed
by activating the respective control medium connectors (connector 2:
open / connector 1: close)

7 Maintenance
• When used as designated, the fitting is practically
wear-free and generally requires no maintenance.
• The operating company must perform regular visual
inspections of the fitting according to the operating
conditions to prevent leaks and damage.
8 Disposal
• When disposing of the fitting and packaging, comply
with the relevant disposal requirements and environ-
mental protection regulations.
• When disposing of fittings, pay careful attention to any
residues of toxic or corrosive media.
9 Return Delivery
Do not return before consulting with emtechnik.
1. Please consult with emtechnik.
2. Empty the fitting properly.
3. Rinse and clean the fitting thoroughly, especially if the
media is being conveyed are harmful, explosive, hot,
or hazardous in some other way.
4. For fittings that have been operated with aggressive,
corrosive, combustible, toxic or water polluting media,
a completely filled in clearance certificate must always
be included.
