1 INTRODUCTION
1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the QSB63P and QSB100P
Pneumatically Operated Quarter Swing Butterfly Valves. You must use the valve as specified in this manual.
Read this manual before you install and operate your valve. Important safety information is highlighted as WARNING
and CAUTION instructions; you must obey these instructions. The use of WARNINGS and CAUTIONS is defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 Description
The QSB quarter swing butterfly valves are quick-acting, high conductance isolation valves designed for use in the
pressure range of 3 bar absolute to 1 x 10-8 mbar (3 x 105to 1 x 10-6 Pa). The valves will resist atmospheric pressure
in either direction.
The valves have a polished stainless steel flanged body with a fluoroelastomer ‘O’ ring sealed butterfly type plate
and shaft. The valve-plate ‘O’ ring groove is vented to help maintain a stable high vacuum. The valve-shaft ‘O’ rings
and bearings are lubricated with Fomblin grease to prevent gas bursts from behind the shaft seals.
The valves are fitted with reed switches on the pneumatic cylinder which indicate when the valves are open or
closed. The reed switches include LED’s for local indication.
1.3 Construction
1.3.1 General
Refer to Figure 1 to identify the item numbers shown in brackets in the following description.
A fluoroelastomer ‘O’ ring (4) seals the valve plate (5) against the valve body (1) when the valve is closed.
Three fluoroelastomer ‘O’ rings seal the valve shaft, as follows:
zThe two dynamic shaft seals (3) isolate the vacuum side of the valve mechanism from atmosphere.
zThe static seal (2) on the blanking plug (8) protects the outer end of the valve shaft from atmospheric
contamination.
All models of the QSB valves are secured in place by the fixing holes in the valve flange. The valve flange faces are
sealed by an Edwards Co-Seal or trapped ‘O’ ring. The flange face dimensions are in accordance with ISO1609:1986
(Vacuum Technology - Flange Dimensions).
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.

INSTALLATION
3 INSTALLATION
3.1 Unpack and inspect
Remove all the packing materials and check the QSB valve.
If the valve is damaged, notify your supplier and the carrier in writing within three days; state the Item Number of
the valve together with your order number and your suppliers invoice number. Retain the packing materials for
inspection. Do not use the valve if it is damaged.
3.2 Install the valve
Position the valve so that the pneumatic actuator and control accessories, if fitted, are accessible but do not cause
an obstruction. Allow sufficient clearance so that the valve plate does not touch any components of your vacuum
system when it is open (see Figure 3).
The valve is normally supported by the pipeline it is fitted to and can be mounted in any orientation. However, we
recommend that you mount the valve with the valve shaft as close to horizontal as possible to reduce particulate
contamination of the valve shaft seals.
If you fit the valve with the flange in the horizontal position, support the valve so that it cannot fall before it is
secured in position.
Connect the valve to your vacuum system with the Co-Seal or trapped ‘O’ ring (supplied) and suitable fixing bolts
(not supplied). The number and size of the bolts that you will need are shown in Table 3.
Table 3 - Fixing bolts required to secure the valve
WARNING
Take appropriate safety precautions when you install the valve in a system in which dangerous
process substances have been pumped.
WARNING
Fit a cover over any exposed part of the valve actuator mechanism, so that fingers or other parts
of the body cannot get trapped.

3.3 Pneumatic connections
Obey your local and national regulations when you connect the air supply and air exhaust to the pneumatic-actuator
of the valve. Note that the fittings provided are designed for use with nylon pipes. Use a dry, filtered air supply to
prolong the life of the pneumatic actuator.
To operate a QSB63P or QSB100P valve, we recommend that you use a 5-port control valve, as shown in Figure 4.

OPERATION
B426-09-880 Issue A
4OPERATION
Note: If a pneumatically operated valve is left closed and is not operated for a long time, when you do operate
the valve, an increased pressure may be required to open the valve; this is due to stiction at the valve plate
‘O’ ring.
Noise may be generated when the valve is used in an air-admittance application, depending on your system
design.
Operation of a QSBP pneumatically operated valve is under the control of the pneumatic circuit. Details of pneumatic
control circuits are subject to local and national regulations and are outside the scope of this manual.
Note that if the pneumatic supply fails, the QSB pneumatic valves will probably stay in the same position (open or
closed), though this will depend on vibration and other external influences on the valve.

MAINTENANCE
5 MAINTENANCE
5.1 General information
QSB valves are designed to require little user maintenance. The only parts which you can replace are the valve shaft
‘O’ rings and the valve plate ‘O’ ring. These have been tested in excess of 1.5 x 105operations before any increased
leak rate (either across the valve or from the system to atmosphere) can be expected. Refer to Section 5.4 for the
replacement procedure. Refer to Section 7 for the Item Numbers of the ‘O’ rings.
5.2 Safety
zEnsure that you do maintenance in a well ventilated area.
zObserve all appropriate safety precautions when you maintain a valve from a system in which dangerous
process substances have been pumped.
zDispose safely of all components which have been contaminated by dangerous process substances (see
Section 6.2).
zDo not use abrasive or reactive chemical substances to clean the valve. Do not use solvents to clean seals or
‘O’ rings.
zDisconnect the pneumatic supply before you remove the valve from your vacuum system.
zDo not operate the valve when it is disconnected from your vacuum system, unless you provide protection
against moving parts.
zLeak test the valve after maintenance to ensure that dangerous process substances do not leak to
atmosphere.
zThe dynamic seals and ‘O’ rings used in this valve are made from a fluoroelastomer. Fluoroelastomers can
decompose into very dangerous substances if they are heated to 260 °C and above. The valve may have
overheated if your vacuum system has been misused or if it has malfunctioned. If the valve has overheated,
ensure that you prevent contact with the seals and ‘O’ rings.
5.3 Maintenance plan
The plan in Table 4 details the maintenance operations necessary to maintain the QSB valve in normal use.
Instructions for each operation are given in the section shown.
Table 4 - Maintenance plan
WARNING
Obey the safety instructions given below and take note of appropriate precautions. If you do not,
you can cause injury to people and damage to equipment.
