Series 290 angle seat & straight seat NC 2/2 valves for GAS applications according to Standard EN 166781 & EN 13611
TM
Bronze body with plastic actuator or stainless steel body with stainless steel actuator, fluid entry above the disc
DESCRIPTION
Series 290 NC 2/2 disc valves comply with European directives
on pressure equipment 2014/68/EU and to the provisions of
regulation EU 2016/426 "Gas appliances".
In the scope of the "Gas appliances" regulation, these valves
meet the specifications of norm EN 16678 for applications
with combustible gases and have been certified.
EU Type examination certificate issued by CERTIGAZ
No.: 1312DM6517
All the valves correspond to class A – group 2 and are suit-
able for gas families 1, 2 and 3.
The arrival of the fluid is made above the disc.
The ambient temperature range is from -10°C to +60°C.
The fluidic performances of the valves are given in the fol-

Minimum pilot pressure measured at the maximum al-
lowable differential pressure.
The Ø 63 actuator is made of plastic or stainless steel.
The valve body is brass when assembled with a plastic
actuator or stainless steel when assembled with a stainless
steel actuator.
The pilot connection can be G 1/8 or NPTF 1/8 or NPT 1/8.
The disc seal is made from PTFE.

OPERATION
(see sectional view, pages 33 and 35)
The valve is closed when the NC 3/2 pilot valve is de-energised.
The valve is open when the NC 3/2 pilot valve is energised.
Fluid entry above the disc, at port 1.
!
Never remove the position indicator sight dome.
The control fluid must be clean air passed through
a 50 µm filter.
INSTALLATION
Install, upstream of the valve and as close to it as possible,
a strainer with a mesh size below 1.5 mm through which
a 1 mm dia. rod cannot pass.
The valves are designed to be operated within the technical
characteristics specified on the nameplate. Modifications to
the products may only be made with the manufacturer's or his
representative's prior consent. Before installation, the piping
system must be depressurized and cleaned inside.
Read and comply with the indications on the label.
Do not exceed the maximum allowable pressure of the valve.
Installation and maintenance is to be carried out by skilled
max.
personnel.
Positioning
The valves can be mounted in any position. For easy access
10
10
to the pilot port, the pilot actuators are rotatable through 360°.
10
Choice of pilot valves
10
10
• The pilot valves used must meet the European directive low
4
voltage and electromagnetic compatibility requirements.
• They must be of the NC 3/2 non-lockable type (without
10
manual operator).
10
• They must allow the main valve to close automatically under
10
the conditions of Standard EN 16678.
10
• They must comply with the technical characteristics indicated
10
in the table below, guaranteeing opening and closing of the
4
main valve within 1 second.
Pilot connection
• Remove the plastic protective plug from the pilot port.
• Connect the pilot solenoid valve directly to the operator
using the nipple provided.
!
The exhaust port plug mounted by the
manufacturer must never be removed.

Connection of valve
Connect the piping as indicated on the body and in these
instructions. Grease the male threads of the tapped pipes
lightly (depending on the application). Do not grease the
female threads of the valve.
Insert a sieve in the circuit entrance: the largest dimension of
the mesh may not be more than 1.5 mm and may not allow
passage with a gauge of 1 mm diameter.
Make sure to avoid any foreign matter entering the system.
The piping must be supported and aligned correctly to avoid
any strain to the valves. Do not use the valve as a lever when
tightening. Locate wrenches as close as possible to the con-
nection point on the bodies and pipes.
To avoid damage to the equipment, DO NOT OVERTIGHTEN
pipe connections.
!
Prior to all maintenance work or putting into operation,
cut off the supply to the pilot, depressurize the valve
and vent it in order to prevent injury to life or property.
!
Removal of the stuffing box to gain access to the
disc must be carried out with the pilot activated and
the disk raised. Each time the valve is removed, the
disc must be replaced.
!
For versions fitted with a signaling box, the detec-
tion positions are set at the factory. Any adjustment
intervention will invalidate the entire certificate for
the entire product.
Cleaning
Maintenance of the valves depends on the operating condi-
tions. They should be cleaned at regular intervals. The intervals
between two cleaning operations may vary according to the
nature of the fluid, the working conditions and the environment
in which it is operated. During servicing, the components must
be checked for excessive wear.
The valves must be cleaned when a slowing down of the cycle
is noticed although the pilot pressure is correct or if an unusual
noise or a leak is detected
Failure to observe these maintenance instructions can result
in faulty operation of the equipment.
Preventive maintenance
• Put the valve at least once a month into operation to check
if it opens and closes.
• The disc seal is available as a spare part. Should any dif-
ficulties arise during installation or maintenance, or should
you have any questions, please contact ASCO or their
authorised representatives.

Installation and Maintenance Instructions
Troubleshooting
• Wrong exhaust pressure: Check the pressure on the
supply side of the valve, it must correspond with the values
indicated on the ASCO nameplate.
• Leaks: Disassemble the valve body and clean the internal
parts. If necessary, replace the disc seal.
Disassembly and reassembly of the valve packing, nut,
washers and body gasket
This operation can be carried out without removing the valve
body from the piping. Before undertaking any maintenance
activity or restart, first disconnect, depressurise and clean
the valve in order to prevent any risk of physical or material
accident.
MAINTENANCE
1. Guide the control head (NC valves) to facilitate unscrewing
the stuffing box.
2. Unscrew the control head and cable gland assembly using
a 24 mm spanner (a) on the flat.
3. Unscrew the nut
If necessary, to prevent rotation, hold the outside diameter
of the valve. Avoid blocking the rod so as not to scratch it.
4. Remove the gasket
5. Clean all the parts that have been made accessible.
Replace the parts identified
the corresponding spare parts kit.
6. Screw the nut back on
the flat.
7. Replace the gasket
8. Replace the actuator tightening it to the recommended torque
values.
Make sure that no foreign matter enters the valve and piping
during the process.
!
Prior to putting the valve into operation, check for
correct operation of the valve in order to prevent
injury to life or property.
!
Do not disassemble the actuator - Spring under load
can cause injury.
!
The valve is not designed to pass positively the fire
test (ISO 10497 et API 607).
