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 owing through it. The downstream
ow 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

Permitted pilot pressure range: 2 – 7 bar.
The pilot pressure should be selected to be as low as
possible to reduce wear on the diaphragm.

Assembly
Type 2036
6.2 Before installation
•Before connecting the valve, ensure the pipelines are ush.
•Pay attention to the ow direction.
6.2.1 Installation position
•The piston-controlled diaphragm valve can be installed in any
position, preferably with connection B downwards.
•Installation for self-drainage of the valve body:
see chapter "Valve self-draining" in operating instruction.
6.2.2 Preparatory work
→Clean pipelines (sealing material, swarf, etc.).
→Support and align pipelines.
Devices with welded connection
NOTE!
Damage to diaphragm or actuator.
▶Before welding in the valve body disassemble the actuator
and diaphragm.
Remove the actuator from the valve body:
→Move the actuator to the upper actuator position (CFA, NC:
by applying pilot pressure; CFB, NO: by removing the pilot
pressure).
→Mark the position of the actuator in relation to the valve body.
→Unscrew the four body screws that connect the valve body with
the actuator. Remove the actuator and the diaphragm.

WARNING!
Risk of injury from improper assembly.
Non-compliance with the tightening torques is dangerous
due to possible discharge of medium and possible release of
pressure.
▶Observe the tightening torque (see "Tab. 2").

6.3.1 Installing the valve body
Welded connection
→Weld valve body in pipeline system.
Other valve body designs
→Connect valve body to pipeline.
6.3.2 Installing the actuator (welded connection)
→Move the actuator to the upper actuator position (CFA, NC:
by applying pilot pressure; CFB, NC: by removing the pilot
pressure).
→Put the actuator / diaphragm on the valve body with correct
alignment (so that the markings made previously align). In the
case of RV110 the four spacer sleeves must be inserted in the
designated body holes (see "Fig. 6: Spacer sleeve").
→Tighten the diagonally opposed body screws / nuts until there
is visible, uniform mechanical contact between the valve
body, diaphragm and actuator.
→Switch the diaphragm valve twice.
Spacer sleeve
Fig. 6: Spacer sleeve
WARNING!
Risk of injury from discharge of medium and release of
pressure.
▶Tighten the body screws suciently (see "Tab. 2").
→Move the actuator to the lower actuator position (CFA, NC:
by removing pilot pressure; CFB, NO: by applying the pilot
pressure).
→Tighten body screws in diagonal pairs in three stages
(approx. 1/3, approx. 2/3, 3/3 of the tightening torque),
according to "Tab. 2".
The diaphragm should be positioned and pressed evenly all
around the actuator and valve body.

6.4 Pneumatic connection
WARNING!
Risk of injury from unsuitable connection hoses.
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶Use only hoses which are authorized for the indicated pres-
sure and temperature range.
▶Observe the data sheet specifications from the hose
manufacturers.
6.4.1 Connection of the pilot medium
To comply with the degree of protection IP65 / IP67 on
the pilot air port which is not required (for CFA, NC and
CFB, NO), install an exhaust air line in the dry area.
For the assignment of pilot air ports refer to the installation and
dimensional drawing included with delivery of the valve.
The use of pneumatic hose with a minimum size of 6/4 is recommended.
For longer hose lengths the hose cross-sections should be adapted
accordingly.
In aggressive surroundings and in situations where
moisture could enter the actuator via the exhaust air port
or muer the exhaust air should be collected and ducted
to a non-critical location.
Control function A:
→Connect the control medium to the pilot air port 1and/or 3
(see "Fig. 7").
Control function B:
→Connect the control medium to the pilot air port 2and/or 4
(see "Fig. 7").
Silencer
→Connect the silencer into the free air discharge connection
(see "Fig. 7").

8 DISASSEMBLY
DANGER!
Risk of injury from discharge of medium and release of
pressure.
It is dangerous to remove a device which is under pressure
due to the sudden release of pressure or discharge of medium.
▶Before removing a device, switch o the pressure and vent
the lines.
If the valve is to be reused after removal, the actuator must
be removed before disassembly where welded bodies are
involved. For this, refer to the assembly instructions.
→Loosen pneumatic connection.
→Remove device.
