INTRODUCING THE DSV...
The DSV is a diaphragm shut-off valve and is designed for the safe, reliable and precise isolation of high purity
and speciality gases across a wide range of demanding gas-handling applications.

It utilises a metal diaphragm and poppet sealing arrangement, providing reliable gas isolation while minimising the potential for contamination and external leakage.

The design is particularly suited to applications where gas purity, leak tightness and repeatable shut-off
performance are critical.

PLEASE CONTACT THE PRESSURE TECH OFFICE IF YOUR ORDER REQUIRES ANY SPECIAL MODIFICATIONS OR REQUIREMENTS.
