Strahman sampling valves extract fluid directly from the pipeline. They can be used under high pressure or even high vacuum conditions.

Strahman’s line of sampling valves produces samples without failure. (Sediment or clogging cannot stop this valve from producing a live sample.) In the closed position, the valve piston extends to the inner surface of the pipe and prevents any possibility of the valve inlet becoming plugged. When the valve is in the open position, the piston retracts into the bonnet allowing a full flow.

The main function of these valves is to draw a live sample from the process. Product may be added to the pipeline through the valve (injection) or removed from the pipeline (sampling).

Plunger Type

Strahman’s line of sampling valves produces samples without failure. (Sediment or clogging cannot stop this valve from producing a live sample.) In the closed position, the valve piston extends to the inner surface of the pipe and prevents any possibility of the valve inlet becoming plugged. When the valve is in the open position, the plunger retracts into the bonnet allowing a full flow. There are no dead spots in the valve. Two compressible valve rings keep the valve sealed and leak free.

Metal Seated Option

In order to keep abreast of customer requirements, Strahman has developed a Metal Seated Sampling Valves for use in ANSI Class 600, 1000°F applications. This valve is dimensionally identical to the Strahman SV Series of Sampling Valves which are the world-wide standard for industrial sampling. A special fabricated bar-stock design is available for ANSI 1500, 1000°F service.
