The Beaver API 600 Cast Steel Bolted Bonnet Globe Valve is suitable for throttling, shut-off,
and on/off services, provided pressure drop isn’t a critical factor when the valve is open.

It has a T-pattern design, which means the stem and disc travel perpendicular to the flow, and the seat opens proportionally to how far the disc has travelled. This gives the valve high flow resistance but also makes it prone to high pressure drop.

The valve has a conical plug disc which rotates freely on the stem at a differential angle to the seat ring. In the closed position, this provides complete shut-off and reduces the risk of the disc sticking in the body seat.

Beaver cast steel bolted bonnet globe valves are available in L31, L32, and L33 models, and exceed requirements set by API 600 standards. You can choose from three different pressure classes (Class 150, 300, and 600) to suit your requirements.
