Vent Valve, NW-25 to 1/4 Inch OD Tube, Bellow Seal, ISO KF-25 Fitting, Stainless Steel

Vent Valves are typically used to introduce air in to the vacuum chamber and bring the system up to atmospheric pressure. These vent valves can be used to fill the vacuum chamber with room air or a N2 gas supply can be plumbed to the 1/4 O.D. tube side of the valve. These vent valves have a NW-25 vacuum flange for connection to the vacuum system, are manually operated, and made of stainless steel.
