The Beaver API 600 bolted bonnet gate valve is a hard wearing, bi-directional cast steel valve suited for applications where minimal pressure loss and a free bore are required. It is often used as a stop or isolating valve.

The valve is design so that when it’s fully open there is minimal obstruction of flow and low pressure drop. A solid, flexible gate is guided to the seats to create a tight seal. The gate’s flexibility means it’s well suited to applications where line loads or thermal expansion could distort the valve’s seat face.

The seat ring is made with corrosion-resistant cast steel and designed to reduce turbulence in the pipe. There are no cavities in the seat to cause build-up or sticking.

This Beaver API600 bolted bonnet gate valve is manufactured according to API 600 standards.
