Manual Gate Valves

Edwards Manual Gate Valves

Edwards BGV gate valves are bellows sealed stainless steel gate valves for use in applications which require high leak tightness and a minimum of hydrocarbons in the vacuum system. Although principally designed for the isolation of pumps in the semiconductor fab basement, BGV gate valves are also ideal in other applications where a 1 bar differential at opening is desirable.

They are designed for use in the pressure range of 1.2 bar absolute to 1 x 10⁻⁸ mbar (1.2 x 10⁵ to 1x10⁻⁶ Pa). BGV gate valves will withstand 1.2 bar absolute in either direction allowing the vacuum line above the pump to be vented with the valve closed. The BGV manual valves have a visual indication of the gate position on the side of the assembly to show when it is open.
