Bolted Manual & Motorized Butterfly Valves

Key High's "Bolted Series" butterfly valves offer high conductance and a small pressure drop due to their narrow profile. Key High's "Bolted Series" butterfly valves are quarter-turn valves that use a circular disc “flapper” that rotates 90° to control the gas flow. In the closed position, the “flapper” is horizontal, closing the bore. In the open position, the flapper is perpendicular to the valve body and the gas flow. Electric valves feature visual position indication.

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 aluminum and 304 stainless steel.
