The Asco 8215G070VH Solenoid Valve (8215G70VH) is a high vacuum solenoid valve designed for air and inert gas breaker and suction/release applications. Built to operate down to 10⁻⁶ Torr, it uses degassed elastomers to maintain vacuum purity and offers precise control with zero minimum pressure differential for critical vacuum environments.
