New Rotary Valve Concept

Analytical Flow Products (Canada) have announced that two new Chinese patents have been recently granted. One of these patents is for their new rotary valve concept with purging grooves design. The other one is for the tight shut off concept of their diaphragm base valves. Refer to Chinese patent CN 101163912 B and CN 101011346 B; both valves series are already in production.

The DV series diaphragm valves are highly popular in sample stream selection, and will have their electrical version ready in January 2011.

This eliminates the need to have actuating gas. In January 2011, a high temperature version of their pneumatic G.C. rotary valve actuator will be released. It can be used directly in an oven up to 300°C, eliminating the need for the traditional standoff. In addition, most of their products literatures are now available in Chinese. Three new distributors have been appointed; Hardee Sales for Louisiana, Mississippi, Alabama and Houston area and Can Flow Technology Inc for the Canadian Market and EIF Filtres for France Market.

Their analytical and sample stream selection valves are now available for the NeSSI™ platform, as per ANSI/ISA- 76.00.02-2002 standard.
