Diaphragm (PTFE)
Special diaphragm construction ensures
gentle opening and closing that prevents
the formation of micro-bubbles.
Piston damper
Absorbs piston momentum to minimize
impact-induced particle generation.
Buffer
Protects diaphragm from deformation
and damage due to back pressure.
Integral fittings construction
Offers quadruple seal construction. Nut lock
mechanism. High flexural strength. Different
tubing sizes can be selected.
Pilot port
Integral clean one-touch fittings construction
Can select female thread (M5).
Body (New PFA)
Compatible with chemicals such as acids,
bases and ultra de-ionized water.
Guide ring
Eliminates lateral motion of the poppet
which reduces internal leakage.
Minimal residual liquid
Residual liquid is minimized by the tapered
shape and integral fitting construction,
allowing liquid to flow smoothly, achieving
improved swept flow characteristics.
