BGV pneumatic gate valve ISO160

The BGV basement gate valves are a range of stainless steel, bellows-sealed basement isolation valves. They have been designed, in conjunction with VAT, to enable pumps to be kept running during foreline maintenance in order to maximise the reliability and up-time of pumps operating on harsh processes. The BGV valves are designed for an operating pressure range of 1 x 10-9 mbar to 1.2 bar absolute (1 x 10-7 to 1.2 x 105 Pa). The valves withstand 1.2 bar absolute in either direction and can tolerate against a 1 bar differential pressure across the valve seal.
 
Although principally designed for isolation of pumps in a semiconductor fab basement, the BGV valves are ideal for other applications where a 1 bar differential at opening is desirable and 20000 cycles is acceptable.

Features and Benefits

  •     Jointly developed with VAT, a world leader in sealing technology.
  •     Stainless steel construction and robust patented design for a long service life
  •     Simple grease-free mechanism minimizes damage due to particulates in dusty processes
  •     Can be operated with 1 bar pressure differential so pressure equalization is not required
  •     Easy servicing with only inexpensive consumables for low cost of ownership
  •     Smooth surfaces for easy cleaning
  •     Available with solenoid fitted and wired for easy ordering and installation
  •     Plug and play compatible with Edwards semiconductor dry pump when used with optional BGV TIM interface cable.
