Blast Gate Valves - Overview • Threaded • Flanged
 These observation ports are for low-pressure applications only.
The Tate-Jones Blast Gate Valves are used to regulate air flow, and the flow of other materials in a variety of applications.
A rugged, cast iron body houses the precision-machined, self-cleaning stainless steel slide. The slide is adjusted easily to any position by a choice of operating mechanisms.
The Tate-Jones Blast Gates are especially suited for low pressure appications where 100% shut-off is not required.
The 3" to 12" Blast Gate Valves have a raised face, and the 14" and 16" valves have a flat face and match the American Standard 125 flange pattern.
RPM flange valves are also available in 4", 5", and 6" sizes.
The standard unit is a Class 30 gray iron with maximum temperature of 425 °F. Custom units made from Carbon Steel and Stainless Steel by special order.
