Specialist selection guide
What should be reviewed before selecting this valve?
A gate valve is designed for full isolation in either the fully open or fully closed position. Lifting the gate from the flow path produces low pressure loss when open, but multi-turn travel, operating time and seat sensitivity make it unsuitable for continuous throttling.
Technical selection path
- 1
Choose wedge, parallel-slide or slab-gate construction for the service and pipeline design
- 2
Evaluate rising or non-rising stem design for space and position indication
- 3
Select bolted, welded or pressure-seal bonnet construction for pressure and temperature
- 4
Check trim and seat materials and hardfacing for corrosion, erosion and galling
- 5
Confirm face-to-face length, pressure class, flanged or welded ends and installation orientation
Key strengths
- Low pressure loss when fully open
- Flow path suited to process lines and selected piggable pipelines
- Broad design range for different pressures, temperatures and materials
Selection limitations
- Not suitable for throttling or sustained partly-open operation
- Multi-turn operation is slower than quarter-turn valves
- Large sizes require more vertical clearance and operating torque
Typical applications
Where can this option be considered?
- Isolation of oil, gas and process-fluid lines
- Lines where low open-position pressure loss matters
- High pressure-temperature duties with suitable construction and trim

Common technical questions
Concise answers before enquiry
Can a gate valve be used for flow throttling?
Generally no. Local velocity and vibration in a partly open position can damage the gate and seats. A gate valve should normally operate fully open or fully closed.
What is the benefit of a rising stem?
Stem travel gives a visible position indication and usually keeps operating threads away from the process fluid, but requires additional vertical clearance.
How do API 600 and ASME B16.34 affect selection?
API 600 addresses heavy-duty steel gate-valve requirements, while ASME B16.34 covers pressure-temperature ratings, materials, construction, testing and marking. The required editions and project provisions must be stated in the order.
