SupelInert Multi-Layer Foil Gas Sampling Bags with Thermogreen® LB-2 Septa

Push/Pull Lock Valve (PLV)

The Push Lock or Pull Lock (PLV) valve is our original gas sampling bag valve fitting which is composed of high-grade inert polypropylene and features our Thermogreen LB-2 septum sandwiched between the film and the valve body; the sample in the bag is not exposed to the septum until it is punctured to remove the sample. This valve design will not deadhead the sampling pump causing an immediate in rush of air when the valve is opened. When the valve is in the closed or locked position (pulled up and turned), the sample flows down the stem of the valve and exits a small hole above the o-ring seal of the valve. When the stem is pushed in to open the valve, the flow is directed into the bag. This valve is an excellant choice when exact flow rates are required. It is securely fastened in the center of the bag and the stem is perpendicular to the bag surface.

Screw Cap Valve (SCV)

The Screw Cap Valve (SCV) is our new valve composed of high-grade inert polypropylene and is a screw cap design with replaceable Thermogreen LB-2 septum in the valve cap. The valve is opened and closed by only turning the cap (not the valve body) one-half turn. The septum comes into contact with the sample during sampling. When the valve is closed, our septum makes the seal to maintain the integrity of your sample. This valve is securely fastened in the upper portion of the bag and the stem of the valve is parallel to the bag. This valve is an excellent choice when your application requires replacing septa.
