Medical grade platinum-cured silicone diaphragms meet USP Class VI and FDA 21 CFR 177.2600 standards.
We provide two different finishes to our silicone diaphragms, white which is made with Q7-4765 and 0.25Â % titanium dioxide or clear with no titanium dioxide.
We also offer a Parylene surface treated version doubling the longevity of the diaphragm.

Valves - tank valves
An integrated steam valve added to our tank-bottom valve. Allows steam-in-place or flush through, without dead legs.
Valves - tank valves
Designed to allow division and blending of two or three fluid paths in a single assembly. Eliminates dead legs.
Valves - tank valves
Created for low-point draining or sampling in piping systems, this valve eliminates dead legs and helps promote drainage.
Valves - tank valves
A valve with a simple clamp connection for easy installation. Allows steam-in-place or flush through, without dead legs.
Valves - tank valves
Used to add ASEPCO valves to existing tanks. Many different designs to fit your specific situation.
Valves - tank valves
Off-centre outlet for full drainability when installed on the slope of a vessel head.
Valves - tank valves
The leading aseptic tank-bottom valve. Available in multiple configurations including custom-machined.
Valves - tank valves
For use in situations where sampling, draining, transferring or directing fluid from a line is necessary.
Valves - tank valves
Designed with through-the-chamber CIP/SIP via 1/4- to 1/2-inch ports, ensuring a truly representative sample every time.
Valves - sampling
Consistent sampling every time. Behind-the-seat-flow path allows for easy clean-in-place/steam-in-place between samples.
