The Carten DCSA series (direct diaphragm design) is designed for gas distribution
and solvent co-axial distribution service where cleanliness, purity and containment
are of primary importance. The DCSA model is a normally closed pneumatically
operated springless, packless, diaphragm valve. It controls the passage of gas or
solvent through the primary tube while providing a complete secondary containment
flow path. The secondary flow path remains open regardless of the primary
passage being opened or closed. The DCSA model is suitable for inert gases, most
toxic gases and most solvents delivering performance, containment and cleanliness
for the process media.
