CAUTION
WARNING
1 Introduction
1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the Edwards GV Gate Valves (referred
to as GV Valves throughout the remainder of this manual). You must use the GV Valves as specified in this manual.
Read this manual before you install and operate the GV 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.
Warnings are given where failure to observe the instruction could result in injury or death to
people.
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
Introduction
The units used throughout this manual conform to the SI international system of units of measurement.
1.2 Description
The GV Valves are bellows sealed gate valves for use in applications which require high leak tightness and a minimum
of hydrocarbons in the vacuum system.
The GV Valves have stainless steel bodies of vacuum brazed construction. The valve bodies have been electropolished
both inside and out and have been baked to 1100 °C during manufacture; this eliminates the possibility of virtual
leaks in the GV Valve and ensures that the GV Valve has low outgassing characteristics.
GV Valves are available with ISO flanges, ANSI flanges and CF (ConFlat®) metal sealed flanges; use CF flanged
GV Valves for applications which require ultra high vacuum and very high baking temperatures. ISO and ANSI valves
are supplied with fluoroelastomer bonnet seals; CF GV Valves have metal bonnet seals. All GV Valves have
fluoroelastomer valve plate seals.
Manual and pneumatically actuated GV Valves are available. The pneumatically actuated GV Valves have position
indicators which can be used by your control equipment to determine when the valve is open or closed:
! GVI*P pneumatically actuated ISO valves have reed switch position indicators (see Section 3.5.2).
! Other pneumatically actuated ISO GV Valves and all pneumatically actuated CF GV Valves have microswitch
position indicators (see Section 3.5.1).
