SECTION CONTENTS GATE VALVE Technical Data 7- VIII HV Gate Valve (with Bellows) 7-1 UHV Gate Valve (with Bellows) 7-3

General Information • UHV Series valves are toggle action, linear travel gate valves. The gate carriage moves In the valve body on a set of wheels, moved back and forth by a manual or pneumatically actuated valve stem which passes through a metal bellows. • To close the valve, the carnage moves forward on wheels until It reaches the end of the valve case. When the carriage stops, the toggle linkage continues to travel and extend. The gate does not move forward, only upward toward the port seal surface. There is no abrasion or damage to the O-ring. The gate moves up to the port into its sealing...

Penumatic Solenoid Connection • A selection of two position indicators are offered by HTC to fill a range of mechanical, and electronic requirements. Signals from the sensor can be employed to activate a variety of external devices such as indicator lights, alarms or other instruments. A valve can be wired so that its accidental opening would affect the shutdown of an entire system for its protection. These position indicators are very useful in automatic process control applications. Signals from the opening or closing of a valve can be employed to trigger complex procedures in computer controlled...

• The HTC stainless steel body offers one of the smallest interior surface areas in the vacuum industry. The body and all major internal components has been welded by TIG (Tungsten Inert Gas), Welding Fixture for the special use ensuring maximum joint integrity. This eliminates the possibility of" virtual leaks " or entrapment areas and minimizes body distortion found in gate valves. For maintenance purposes, the carriage assembly can be removed from the body without removing the valve from the system. These valves can be used with cryo-pumps, turbo molecular pumps or in any applications requiring...

• Here are some general options that are available with most of our valve products. These options are in addition to whatever features you choose for your valve. (See the Gate Valve Ordering Information for more information on these features.) • 1 .Flange Options: Port flanges are available in a variety of configurations and geometries. The more common flange types are listed here. Others are routinely supplied, please call the factory for information. • 2.Solenoid Control Valves: HTC valves with pneumatic actuators are supplied with a 110 VAC, 60 Hz solenoid control valve. Other solenoids are...

Numbering System • This numbering system was developed to insure the valve supplied is exactly what you need. It addresses questions concerning available features and options for the valve, and incorporates that information in the valve number. Valve Body Type A=Bellows type (SS) (O) (Bonnet) * * B=Bellows type (SS) (M) (Bonnet) * * Gate O-Ring Meterial Port Flange Neck Style 1=Tapped Holes Both Side 2=Neck Flange on Both Side 3=Neck Flange on Seal Side 4=Neck Flange on Open Side * ANSI / VG (S) is flange with o-ring on seal side. * ANSI / VG (O) is flange with o-ring on open side. * * Bellows...
