Bolted Bonnet Gate Valve

These high quality bolted bonnet gate valves are usually installed in a large variety of services in the oil and gas industry, chemical and petrochemical industry, in onshore and offshore drilling/refining, and in the power industry. The bolted bonnet gate valves are successfully installed worldwide on applications requiring tight shutoff.

The bolted-bonnet joint of the gate valve is the most popular joint and it is used on the majority of gate valves in the industrial use today.

Unlike threaded and union bonnet valves, the bolted-bonnet connection requires a gasket to seal the joint between the body and bonnet. At lower pressure valves, sheet gasket materials are used and at higher pressure metallic gaskets are used to seal the bolted bonnet gate valve.
