Valves and flow control
Limit-switch box
Managing flow within process piping
Specialist selection guide
What should be reviewed before selecting this product?
Limit-switch box belongs to the Actuators and control accessories 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 torque or thrust from the project specification and verify it against the manufacturer proposal
- 2
Extract motion type from the project specification and verify it against the manufacturer proposal
- 3
Extract power source from the project specification and verify it against the manufacturer proposal
- 4
Extract duty cycle from the project specification and verify it against the manufacturer proposal
- 5
Extract ingress protection from the project specification and verify it against the manufacturer proposal
- 6
Extract redundancy and safety from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Actuators and control accessories 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 Limit-switch box?
At minimum provide torque or thrust, motion type, power source, duty cycle, ingress protection and fluid conditions. Final documentation requirements follow the project specification.
Are two Limit-switch box 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
