M-201-T Series
Design Considerations/Construction
The M-201-T Series comprises a Body, Piston, and PTFE coated Spring. The M-201-T Series contains two moving parts (i.e. the
piston and spring) and a retaining ring that are in the fluid path. Construction of the piston is important from a design
perspective. A PTFE Encapsulated piston is used in this switch to ensure that all wetted parts are PTFE or PTFE coated.
