Butterfly Valves

Butterfly valves are available in sizes ranging from 2" to 24" and can handle 175 psi working pressures. Body styles come in Lug, Notched and Wafer types. Stem extensions, long and short neck models are available. Due to a low profile disc design, these butterfly valves provide superior flow regardless of style or size.

Inside BOP Valves

Protect your pumps, swive, standpipe, and from drill-string kicks with the inside B.O.P valve. Use the inside BOP valve anytime well kicks are expected, like when drilling through transitional zones. It is designed to be run thru most BOP stacks as an integral string part. The top vent allows fluids to partially flow by allowing safer and faster emergency stabbing.
