New Product Launch: VWB Series Compact Vacuum Bellows-Sealed Valves

New Product Launch VWB Series Compact Vacuum Bellows Valve

 

Introduction

 

 

VWB Series Compact Vacuum Bellows-Sealed Valves are designed for instrument and line isolation in vacuum systems. They can also function as venting, bypass, or roughing valves.

 

VWB Series Compact Vacuum Bellows Valve

 

When instruments are used to control vacuum system pressure, the small internal valve volume of the VWB Series helps shorten instrument response time.

During venting of the vacuum system to atmosphere, the VWB Series can isolate the sensor from the system chamber, preventing overpressure damage to the diaphragm of a capacitance diaphragm gauge.

When monitoring system pressure, the VWB Series isolates the instrument from the process, preventing contamination of the pressure gauge by process gases.

For soft start-up of a vacuum system, installing a VWB Series valve with low conductance in a bypass line allows the system pressure to decrease gradually from atmospheric pressure to the desired vacuum level, thereby preventing particle entrainment within the vacuum chamber.

 

Features

 

 

  • Compact design with a small internal valve volume
  • Formed 316L stainless steel bellows for reduced particle generation and particle entrapment
  • Bodies welded using Tungsten Inert Gas (TIG) welding to reduce internal dead space and ensure high cleanliness
  • Optional angle or inline configurations and mountable in any orientation
  • Variety of connection sizes and types available
  • Pneumatic or manual actuators available
