Specification Review
globe valve vs gate valve
Resolve globe valve vs gate valve before selecting a supplier. The decision is duty and access, not a catalog synonym. A gate is typically specified for isolation with a low pressure-drop preference when the disc is fully open. A globe is typically specified when the buyer needs characterized throttling or a defined seating stroke. Neither type is released by this page as interchangeable. Maintenance access for a pressure-seal bonnet and the actuator orientation against the piping layout must be written before award.

Decision dependencies
-
Input dependency
- Required input
- Buyer-owned isometric or sketch showing end connection, face-to-face, stem or actuator centerline, and the overhead or side access needed to service a pressure-seal bonnet. Fluid, working pressure, temperature and duty cycle travel with that sketch.
- Owner
- The buyer or the buyer’s process engineer owns the duty and layout. Globe Valve Sourcing restates those inputs; it does not invent missing access dimensions.
-
Review dependency
- Named manufacturer confirms whether a globe or a gate is being offered, what access the bonnet needs, and which end connection and actuator orientation match the piping layout.
- Unresolved question: if the layout cannot accept the stem height of a pressure-seal globe, is a bolted-bonnet globe or a gate the intended substitute, and is that substitution labeled?
