Bolted Electropneumatic Butterfly Valves & Mating Flanges

Key High's "Bolted Series" pneumatic valves are a family of quarter-turn isolation valves used to control gas flow within large tubes. Their simple construction and compact design result in lighter weights and smaller installation footprints. These valves are well suited for handling large gas flows.
 
Key High's "Bolted Series" pneumatic valves offer the fastest actuation, much faster than a similar-sized gate valve. Butterfly valves have fewer parts than gate valves, are mechanically simple, and offer a significant economic benefit compared to other valve types. The larger the valve, the larger the cost savings.
 
Key High's "Bolted Series" valves are available with seven (7) standard bore sizes, 1-1/2” through 6”.  The body and flapper materials in the "Bolted Series" valves are 6061T6 alumin
