Basic safety instructions
Type 2036
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• Contingencies and events which may arise during the installation,
operation, and maintenance of the devices.
• Local safety regulations – the operator is responsible for observing
these regulations, also in relation to the installation personnel.
DANGER!
Risk of injury from high pressure in the equipment/device.
▶Before working on equipment or device, switch off the pressure
and deaerate/ drain lines.
Risk of electric shock.
▶Before working on equipment or device, switch off the power
supply and secure to prevent reactivation.
▶Observe applicable accident prevention and safety regulations
for electrical equipment.
WARNING!
Risk of injury when opening the actuator.
The actuator contains tensioned springs. If the actuator is opened,
injuries may be caused by the springs jumping out!
▶The actuator must not be opened.
CAUTION!
Risk of burns.
The surface of the device may become hot during long-term operation.
▶Do not touch the device with bare hands.
Risk of being crushed by moving spindle ends.
▶Install transparent cap.
Generally hazardous situations.
To prevent injuries:
▶Ensure that the system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶After an interruption in the electrical or pneumatic supply, ensure
that the process is restarted in a defined or controlled manner.
▶The device must only be operated when in a perfect condition and
in consideration of the operating instructions.
▶The general rules of technology must be observed for application
planning and operation of the device.
To prevent material damage:
▶Supply only media to the media connections that are specified in
chapter "5 Technical Data" as flow media.
▶Do not place the valve under mechanical stress (e.g. by placing

Basic safety instructions
Type 2036
3.1 Use in Ex area
Abbreviation “Ex”: see chapter "1.1 Definition of term / abbreviation"
3.1.1 Safety instructions
For operation in Ex area Zone (gas) 1 and 2,
Zone (dust) 21 and 22, the following
applies:
The valve actuator is suitable for use as a Category 2 device for
Zone 1 and 21, non-electrical production equipment.
DANGER!
Danger of explosion caused by electrostatic charge.
Depending on the conductivity of the medium, electrostatic charges
may occur on the valve membrane if plastic bodies are used.
To prevent electrostatic charges in the fluid, the following instructions
must be observed (as per IEC 60079-32-1):
▶(1) Media with a conductivity ≤ 100 pS/m may only be used if no
flow speeds > 1 m/s occur or if the possibility of the pipe system
running dry is excluded by suitable monitoring.
▶(2) Media with a conductivity > 100 pS/m and ≤ 1000 pS/m may
only be used if they are liquids without any particles, steam or pure
gases/steam, or if the instructions in (1) are observed.
▶(3) Media with a conductivity > 1000 pS/m are not subject to any
restrictions.
Further instructions:
▶The user must ensure that the appliance is used in Zone 1/21 or
2/22 only.
▶The control unit may restrict use in an explosive atmosphere. Follow
operating instructions for control unit.
▶Check that any cleaning agents are approved for use in explosive
atmospheres.
3.1.2 Media temperature
DANGER!
▶If explosive media are used this can cause additional explosion risks.
▶If media temperatures are used between 130 °C and 150 °C,
the temperature class T3 / 200 °C applies (dust).
Media temperature max. 130 °C
3.1.3 Ex marking
PTB 13 ATEX D103 X

II 2D c T135°C
Warning: Not valid when Non-Ex devices added.
Do not open actuator. Spring loaded cover.

General information
Type 2036
The Ex marking is not valid if Non-Ex devices are added.
3.2 Special conditions
→To ensure potential equalization, ground the valve body to the
pipe system using an electrically conductive connection.
DANGER!
Danger of explosion caused by electrostatic charge.
In the event of a sudden discharge from electrostatically charged
devices or individuals there is a risk of an explosion in the Ex area.
▶Implement suitable measures to ensure that there are no
electrostatically charges in the Ex area (see also "3.1 Use in Ex
area").
▶Clean the device surface by gently wiping it with a damp or anti-
static cloth only.
▶Earth the actuator and valve body.
▶If a plastic body is used, earth the actuator separately.
Ambient temperature range: 0 °C ≤ Tamb ≤ 60 °C

Technical Data
Type 2036
Remarks
Static leak-tightness:
Valve is closed (diaphragm is in contact with the body seat). One
side of the body seat is under pressure. At the given pressure no
leakage takes place via the body seat.
Dynamic leak-tightness:
Valve is open and the medium is flowing through it. The downstream
flow is only slightly throttled by components placed downstream.
Both sides of the body seat are under pressure. The valve is closed
(CFA, NC via spring force; CFB, NO via pilot pressure). At the
given pressure the valve closes onto the body seat and the seal is
complete.
Static leak-tightness: Dynamic leak-tightness:

The following graphs illustrate the required minimum pilot pressure
depending on the medium pressure for control function B.
Permitted pilot pressure range: 2 – 7 bar.
The pilot pressure should be selected to be as low as pos-
sible to reduce wear on the diaphragm.
