Valves and flow control
Lockout valve
Managing flow within process piping
Specialist selection guide
What should be reviewed before selecting this product?
Lockout valve belongs to the Manual and mechanical valves family. Technical selection must start from actual service conditions, followed by verification of dimensions, pressure-temperature duty, material, connection, construction standard, testing and manufacturer documentation against the project piping class.
Technical selection path
- 1
Extract valve duty from the project specification and verify it against the manufacturer proposal
- 2
Extract class and design pressure from the project specification and verify it against the manufacturer proposal
- 3
Extract temperature and fluid from the project specification and verify it against the manufacturer proposal
- 4
Extract body, trim and seat materials from the project specification and verify it against the manufacturer proposal
- 5
Extract end connection and face-to-face from the project specification and verify it against the manufacturer proposal
- 6
Extract leakage class from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Manual and mechanical valves family
- Compatibility review across project materials and connections
- Structured technical comparison before final enquiry
Selection limitations
- A trade name or product name alone does not define the technical specification
- Pressure-temperature limits depend on material, design and standard edition
- Substitution requires dimensional, functional and documentation verification
Typical applications
Where can this option be considered?
- Evaluation for Oil and gas projects subject to service-condition approval
- Evaluation for Refining projects subject to service-condition approval
- Evaluation for Petrochemical projects subject to service-condition approval

Common technical questions
Concise answers before enquiry
What information is required to enquire about Lockout valve?
At minimum provide valve duty, class and design pressure, temperature and fluid, body, trim and seat materials, end connection and face-to-face and fluid conditions. Final documentation requirements follow the project specification.
Are two Lockout valve products with the same name interchangeable?
No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.
Isolation, control, protection or automation as required by design
Pressure, temperature, fluid, leakage, materials and operation
