ESCO-Labor piston valves are designed for controlled removal of liquid, powder, and granular materials from process equipment.
As part of the ESCO-Labor Process Systems family, these valves support bottom outlet and sampling valve applications where material discharge or sample removal must be handled cleanly and efficiently within the process setup.
The piston valve design is described as dead-space free, helping reduce areas where material may remain inside the valve body during removal.

This makes the valve suitable for applications where process material needs to be discharged or sampled without unnecessary hold-up.
ESCO-Labor also identifies the valve for use without interrupting the process, supporting its role in process-oriented laboratory and production environments where controlled removal is part of the operating sequence.
The piston valve’s supported function: removal of liquid, powder, and granular materials, as well as use as a bottom outlet valve or sampling valve.
