Drain valves, also known as bottom tank valves or piston valves are used to empty vessels or take process samples. The basic Strahman drain valve design includes a piston or "ram" that extends into the vessel outlet to prevent accumulation of process material.

Strahman drain valves are used on process vessels and reactors and are designed so that they cannot clog. They are ideal for use in liquid and gas service or with slurries, polymers, and high viscosity fluids, which may solidify at room temperature. Drain Valves are available in Disc Type or Plunger Type.

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.) The main function of these valves is to make a link between the inside and the out side of a process. Product may be added to the pipeline through the valve (injection) or removed from the pipeline (sampling).
