What are Bolted Bonnet Globe Valves

Bolted Bonnet Globe Valves (manual globe valves) are used for throttling control. Closure is achieved by moving the disc against the air flow rather than across the disc like gate valves.

We focus on valves in standard and special materials as customer request.
