Butterfly Valve Figure 55

The figure 55 is a double flanged valve design for

services in the water treatment industry like potable
water, water treatment and wastewater applications.

Features
The centric disc offers bidirectional service
and allows with its symmetric shape high
Cv values
The bonded seat protects the shaft
against the medium
Primary stem sealing by preloaded
contact between flatted seat surface and
rounded polished disc-hub area exceeds
the pressure rating of the valve and
prevents leakage through shaft area to
atmosphere
Actuator flange acc. ISO 5211
Double flanged body design specified acc.
ISO 5752/4 series 13 (short), series 14
(long) on request
The inside body is protected by a bonded
rubber liner extending over the flanges
Rounded, polished disc edge provides
concentric sealing
A secondary sealing is provided by the
interference fit between shaft and
shafthole in seat at all positions
Dirtscraper prevents moisture penetrating
into the shaft area
Bubble-tight shut of at full pressure rating
Excellent performance in media with
sedimentation and contamination
Suitable for severe vacuum applications
and up to 230 psi bubble tight shut off

valve data

Note
1. Rated Cv = the volume of water in USgpm
that will pass through a given valve opening
at a pressure drop of 1 psi.

Notes
1. The given maximum allowable torques are
applicable for standard type valves.
2. In ISO 5211/2 a table is listed representing
the maximum torques which can be
transmitted through the mounting flange.
These values are based upon specific criteria
and can be lower than the maximum
allowable shaft torques. In this case the
criteria can be changed in order to reach the
maximum allowable shaft torques.

Notes
1. Dynamic operating torque formula:
TD = FT x P
TD =
P =

Dynamic torque (Lbf. inch)

Pressure drop across disc at
desired disc-opening (psi)
FT = Dynamic torque factor
(see table)
2. The above mentioned dynamic torque
includes all frictional resistances.
3. The dynamic torque is tending to close the
disc.

Notes
1. Application I :
Water, seawater, lubricating types of
hydrocarbons. Temp.: 32-176F;
Valve opens at least once a month.
Application II :
All other liquid applications and lubricating
gasses.
Application III :
Non lubricating and dry media.
2. The charted maximum sizing operating
torque is the sum of all friction and resistance
for opening and closing of the disc against
the indicated pressure differential.
3. The effect of dynamic torque is not
considered in tabulation.
4. In sizing operators it is not necessary to
include safety-factors.
