AP1 / MS4 / MSP4 aseptic valves
Hermetic separation of product from the environment with a PTFE diaphragm — for aseptic processes in food, dairy and pharma.
REF · ASEPTIC
Product with no contact to the outside
A flexible diaphragm separates the product chamber from the drive. The valves isolate line sections and aseptic tanks, dose and take samples.
Why AP1 / MS4 / MSP4 aseptic valves
3-A approved
AP1, MS4 and MSP4.
Leak detection
Single-layer diaphragm — a leak is visible at once.
High temperatures
Operation at high temperatures and up to 10 bar.
ATEX
ATEX-compliant models.
