Correct Usage of the A-DR20 Direct-acting Pressure
Reducing Valve
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
1. The A-DR20 should be operated only within its specifications.
2. Installing an ON/OFF Valve (Solenoid Valve or Motorized Valve)
If an on-off valve is required to stop supply of air to the air-using equipment, install
it at the inlet side of the A-DR20.
If a solenoid valve is installed at the outlet of the A-DR20, it will cause heavy
chattering and may lead to damage of the A-DR20. (When the on-off valve opens,
the secondary pressure of the A-DR20 changes from zero to the set pressure.
Passing through an area of the reducing ratio of less than 30:1 where adjustment
is impossible, chattering occurs momentarily.) To save energy, install the on-off
valve as near to the boiler, or compressor, as possible.
NOTE: To prevent water hammer, it is recommended that a slow-acting motorized
on-off valve be used. If a fast-acting solenoid valve is used, the potential
water hammer effect can damage the air-using equipment and the
pressure reducing valve.
3. Installing a Control and/or Safety Valve
A control valve (i.e. for temperature
control) installed between the
A-DR20 and the air-using equipment
(downstream of the
A-DR20) may raise the pressure
between the A-DR20 and the control
valve when the control valve is
closed, depending on their proximity.
Therefore, this valve should be
installed close to the
air-using equipment, as illustrated.
Also, a safety valve should be
installed downstream of the control
valve.
NOTE: When installing a safety valve to protect the air-using equipment, be sure to
install it on, or directly before the inlet, of the air-using equipment. If the
safety valve is installed between the A-DR20 and a control valve, an
eventual pressure rise could activate the safety valve.

4. Recommended Straight Pipe Runs
In order to ensure a stable flow of air, the piping upstream and downstream of the
A-DR20 must be straight runs. If the A-DR20 is installed either directly before or
after an elbow or control valve, unevenness in flow may result in chattering and
unstable pressure.
To ensure a stable air flow, it is recommended that the A-DR20 be installed on
straight runs of piping, as illustrated below.
(1) Inlet (primary side) of the A-DR20 NOTE: d = pipe diameter
Maintain a straight piping
run of 10 d or more
when a manual valve, a
strainer or an elbow, etc.
is installed.
(Example: if nominal size
is 25 mm (1 in), have
250 mm (10 in) or more)
Maintain a straight piping
run of 30 d or more
when an automated
valve (on-off valve) is
installed.
(Example: if nominal size
is 25 mm (1 in), have
750 mm (30 in) or more)
Maintain a straight piping
run of 30 d or more
when another pressure
reducing valve is
installed. (Two-stage
pressure reduction)
(Example: if nominal size
is 25 mm (1 in), have
750 mm (30 in) or more)
(2) Outlet (secondary side) of the A-DR20
Maintain a straight piping
run of 15 d or more
when a manual valve, a
strainer or an elbow, etc.
is installed.
(Example: if nominal size
is 25 mm (1 in), have 375
mm (15 in) or more)
Maintain a straight
piping run of 30 d or
more when a safety
valve is installed.
(Example: if nominal size
is 25 mm (1 in), have 750
mm (30 in) or more)

Installation
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
1. Blowdown
Blowdown Using a Bypass Line
Before installing the A-DR20
unit, be sure to blow down all
piping thoroughly. If this is not
possible, perform a blowdown
using the bypass valve.
Blowdown is especially
important for newly installed
piping or after the system has
been shut down for a long
period of time.
2. Removing the Protective Caps
Before installation, be sure to remove all protective seals and caps
covering the product inlet and outlet.
(Found in 2 locations; on the product inlet and outlet.)
3. Installation Angle
4. Piping Support
Install the A-DR20, paying attention to avoid excessive load,
bending and vibration. Supporting the inlet and outlet pipes
securely.

6. Piping Size/Diffuser
If the secondary air flow
velocity is expected to be
more than 30m/s (100
ft/s), install a diffuser in
order to keep the flow
velocity below 30m/s
(100 ft/s). If the distance
between the A-DR20 and
the air-using equipment
is great, a possible drop
in pressure should be
taken into consideration
when selecting the piping
size.
In addition, when
installing the strainer, the
strainer screen should
be either at the 3 o’clock
or 9 o’clock position to
prevent condensate
accumulation..
7. Two-stage Pressure Reduction
Install a pressure reducing
valve at the inlet side of the
A-DR20 wherever the
pressure cannot be reduced
to the desired level with a
single A-DR20 due to
operating range limitations,
such as when the reduction
ratio is greater than 30:1.
8. Accessories
Always install a shut-off valve, pressure gauge and bypass lines at both inlet and outlet.
Ball valves, which will not retain condensate, are recommended for inlet and outlet shut-
off valves. The bypass pipe should be at least ½ of the size of the inlet (primary) pipe.

Adjustment
To avoid problems such as water hammer and to protect air-using equipment, the
A-DR20 should be properly adjusted.
1. It is necessary to blow down all pipe lines thoroughly.
The blowdown is especially important if the line is new or has been shut down for a
long period of time. Take particular care to ensure that matter such as condensate
and dirt does not remain inside the air-using equipment.
(Stay clear of any pressurized blow-out from the safety valve.)
2. Make sure that the shut-off and bypass valves
located upstream and downstream of the
A-DR20 are completely closed.
3. Loosen the locknut, then turn the adjustment
handle counter-clockwise to free the coil spring.
4. Slowly, fully open the shut-off valve at the inlet of
the A-DR20.
5. Slightly open the shut-off valve at the outlet of the A-DR20.
6. Turn the adjustment handle clockwise until the
desired outlet pressure is obtained. Wait
several minutes.
7. Slowly, fully open the shut-off valve at the
outlet of the A-DR20.
8. After setting, retighten the locknut.
9. When shutting down the system, always
close the outlet shut-off valve first and then
the inlet valve.

Disassembly
When disassembling or removing the product, wait until the internal
pressure equals atmospheric pressure and the surface of the product
has cooled to room temperature. Disassembling or removing the
product when it is hot or under pressure may lead to discharge of fluids,
causing burns, other injuries or damage.
CAUTION
It is a recommended practice to dismantle and inspect the A-DR20 once a year for
preventive maintenance purposes. It is especially important to perform an inspection
immediately after the initial run of a new line or before or after equipment is taken out
of service for a long period of time.
(Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.)
Remove all pressurized air from the piping (both upstream and downstream).
Remove the A-DR20 from the piping, and secure it in a vise to perform disassembly
and inspection.

Reassembly
Assemble the unit using the same procedure as used for disassembling it; but in
reverse order. Observe the following precautions:
1. The PTFE gaskets may be re-used if free from fault, crushing or deformation.
2. Apply anti-seize to the steel ball and threaded portions of screws, bolts and the
adjustment handle. Apply a small amount of anti-seize agent to the threads of
the valve seat carefully to ensure it does not come into contact with other parts.
3. Fasten the bolts one at a time in a diagonal pattern alternately to provide
uniform seating.
4. After assembly, make sure that the valve stem operates smoothly without binding.
As shown in the figures above, when the main valve is tightened it may become
off-centered on the valve seat. If this occurs, move the main valve back to center.

maintenance by persons other than TLV or TLV group company personnel, or
service representatives authorized by TLV; or
4. disasters or forces of nature or Acts of God; or
5. abuse, abnormal use, accidents or any other cause beyond the control of TLV,
TII or TLV group companies; or
6. improper storage, maintenance or repair; or

AND ALL OTHER WARRANTIES, INCLUDING BUT NOT LIMITED TO THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE,
ARE EXPRESSLY DISCLAIMED.
Severability
Any provision of this warranty which is invalid, prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity,
prohibition or unenforceability without invalidating the remaining provisions hereof,
and any such invalidity, prohibition or unenforceability in any such jurisdiction shall
not invalidate or render unenforceable such provision in any other jurisdiction.
