Viton® is a class of fluoropolymer elastomer (synthetic rubber) and is well known for its excellent heat, acid and chemical resistance. The performance of fluoroelastomers in aggressive chemicals depends on the grade of the elastomer.
There are three grades of Viton we currently use for our viton diaphragms:
Diaphragm variant(s) | Bellows, Straight |
Compatible actuators | AJS, AKS |
Compatible valves | Radial |
Material specification | Fluoropolymer elastomer, Peroxide cured F-type gum polymers, Steam resistant Viton A |
Standards | ASME BPE, RoHS |
Technical Summary table lists features available within the range. See ‘Specifications’ tab for model specific information.

The leading aseptic tank-bottom valve. Available in multiple configurations including custom-machined.
Valves - tank valves
Our best-selling in-line valve featuring a 180 degree install angle with superior drainability in multiple orientations.
Valves - inline valves
Consistent sampling every time. Behind-the-seat-flow path allows for easy clean-in-place/steam-in-place between samples.
Valves - sampling
Designed to allow division and blending of two or three fluid paths in a single assembly. Eliminates dead legs.
Valves - tank valves
Use with freeze tanks or tanks requiring critical temperature control. Extended body and diaphragm.
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
An integrated steam valve added to our tank-bottom valve. Allows steam-in-place or flush through, without dead legs.
Valves - tank valves
Off-centre outlet for full drainability when installed on the slope of a vessel head.
Valves - tank valves
For use in situations where sampling, draining, transferring or directing fluid from a line is necessary.
Valves - tank valves
Eliminate the usual dead leg between seal points, in a reliable block-and-bleed valve.
