Valves and flow control
Two-way servo assisted
Automatic fluid switching from an electrical command
Specialist selection guide
What should be reviewed before selecting this product?
Two-way servo assisted belongs to the Solenoid 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 normal position from the project specification and verify it against the manufacturer proposal
- 2
Extract minimum differential pressure from the project specification and verify it against the manufacturer proposal
- 3
Extract voltage and power from the project specification and verify it against the manufacturer proposal
- 4
Extract diaphragm and seal material 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 response time from the project specification and verify it against the manufacturer proposal
Key strengths
- Selection within the established Solenoid 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 Two-way servo assisted?
At minimum provide normal position, minimum differential pressure, voltage and power, diaphragm and seal material, ingress protection and fluid conditions. Final documentation requirements follow the project specification.
Are two Two-way servo assisted products with the same name interchangeable?
No. Installation dimensions, pressure-temperature rating, wetted materials, connection, test method and material certification must be checked independently.
