Types BLE and BLX

OPERATION

Type BLE or BLX

The Type BLE throttle valve is a balanced plug type, opened

by pressure ow.

The opening control is manually performed by a torque
handwheel (approx. 4 N
(see Table 4).

Tight shutoff is achieved by a nitrile disc plug situated on the

valve plug. The disc plug and orice are easily replaced.

The opening control is progressive to start and then linear.
In closed position, an O-ring situated below the handwheel
protects the control screw for exterior corrosion.

A rotation of 1/8 turn after contact with the valve plug / orice
is sufcient to assure tight shutoff.

Slam-Shut (Type BLX)

The pressure of the zone to be protected (in general the
pipeline, outlet side of the regulator and after the slam-shut)
reacts on the safety manometric box (BMS).

•m). 1 handwheel turn = 2 mm travel

If the pressure rises above the set range, the release relay
releases the valve plug.

Due to the action of the closing spring and the uid (trying to
close), the valve plug closes on the orice.

The gas ow is obstructed until the fault has been corrected

and the mechanism box manually rearmed.

Equal pressure balance on inlet and outlet sides are
necessary to reopen the valve plug.

The mechanism box is rearmed after opening the
internal bypass.

Rearming and balancing are achieved at the same time.

INSTALLATION

WARNING

!

Personal injury or equipment damage, due
to bursting of pressure-containing parts
may result if this device is overpressured or
is installed where service conditions could

exceed the limits given in the Specication

section and on the appropriate nameplate
or where conditions exceed any rating of
the adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices to prevent service conditions
from exceeding those limits. Also, be sure
the installation is in compliance with all
applicable codes and regulations.

Figure 4. Types BLE and BLX Installation

Additionally, physical damage to the device
can cause personal injury and property
damage due to bursting of pressure­containing parts. To avoid such injury and
damage, a possible approach could be e.g.
install the device in a safe location.

Respect the direction of the uid ow and the
position of the valve (uid opening the throttle

valve plug).

All interventions on the equipment should
only be performed by qualied and
trained personnel.

Type BLE version, the valve is to be installed on
horizontal or vertical pipeline with the control
handwheel in a top, bottom or lateral position.

B75

4

Types BLE and BLX

Type BLX version, the valve is to be installed
on a horizontal pipeline with the control
handwheel in a top or bottom position.

Install according to direction of uid ow
(arrow). Opened by uid ow.

When assembling with adjacent elements
care must be taken not to create pressure
force on the body and the assembling

elements (bolts, O-rings, anges) should be

compatible with the geometry and working
conditions of the equipment.

If the case arises a support must be used to
avoid pressure force on the body (a support

can be installed under the anges).

No modication should be made to the

structure of the equipment (drilling,
grinding, soldering...).

Verify that the inlet side is protected by an
appropriate device(s) to avoid exceeding the
limits of utilization (PS, TS).

Verify that the limits of utilization correspond
to the appropriate operating conditions.

Type BLX version, verify that the safety
manometric box (BMS) and spring correspond
to the appropriate operating conditions on the
outlet side of the throttle valve.

The equipment should not receive any type
of shock, especially the handwheel and
release relay.

COMMISSIONING

WARNING

!

All interventions on the equipment should
only be performed by qualied and
trained personnel.

Be sure to slowly introduce pressure into the
system to prevent downstream overpressure
due to potential rapid pressure increase.
Pressure gauges should always be used to
monitor downstream pressure during startup.
