Chemola™ Delta “HF” Series
Two-Piece Sure Seal Fitting
The Chemola™ Delta “HF” Series is a two-piece double check fitting that is designed for a positive seal under extreme conditions, such as hydrofluoric acid service. The top fitting is backed out a few turns, and the valve is lubricated using a Chemola™ Delta high-pressure grease gun. The top fitting is then screwed back into the bottom fitting until the tapered metal-to-metal seat forms a positive seal. The two-piece construction has one check ball in each of the two pieces. It is rated for service to 10,000 psi.
Also available in stainless steel.
