F11 F22 F51 Gate Valve for Power Plant Isolation
A project-specific gate valve for on-off isolation in power plant piping. The F11, F22 or F51 material designation, together with all pressure, temperature, trim, connection and testing requirements, must be confirmed in the approved datasheet.
| Valve Type | Gate Valve | Primary Function | On-off isolation |
|---|---|---|---|
| Material Designation | F11 / F22 / F51, as specified | Size & Pressure Rating | To be specified in the RFQ |
| End Connection | To be specified in the RFQ | Operating Conditions | To be specified in the RFQ |
| Design Standard | To be specified in the RFQ | Operation | To be specified in the RFQ |
Configuration scope: F11, F22 and F51 are separate material designations and must not be treated as interchangeable selections. The exact material standard, product form, valve construction, pressure-temperature rating, trim, end connection, inspection and documentation requirements must be confirmed against the approved project specification.
Frequently Asked Questions
Please provide the selected material designation, valve size, pressure rating, design pressure and temperature, medium, end connection, operating method, quantity and applicable project standard.
Not automatically. They are separate material designations. Each requested configuration must be reviewed against the applicable material standard, service conditions and approved datasheet.
The valve is intended for on-off isolation. It should normally be specified for fully open or fully closed operation rather than routine flow regulation.
No universal range is stated on this page. Available size and pressure rating will be confirmed after the RFQ and project specification are reviewed.
Required material certificates, drawings, pressure-test records, inspection plans, NDE records or third-party inspection must be stated in the inquiry and confirmed in the order documents.
Product Overview
Vornet F11 F22 F51 Gate Valve is presented as a project-specific isolation valve for power plant piping. The page does not assign one universal pressure, temperature or dimensional range to all three material designations.
Valve construction and the complete bill of materials are reviewed from the purchaser’s datasheet. The final offer identifies the exact material designation, size, pressure rating, trim, end connection, operating method, testing and documentation scope.
Purchasers should submit complete operating and specification data so that the offered valve can be checked against the actual service requirements.
- Clear Material Identification: F11, F22 or F51 is confirmed for the specific quoted configuration.
- Isolation Duty: Specified for fully open or fully closed service.
- Project Review: Dimensions, rating, construction and testing are confirmed from the RFQ.
- Documented Supply Scope: Inspection and documentation requirements are agreed before manufacture.

For Indian power-project tenders and other high-temperature isolation duties, confirm the valve against the piping class and coincident pressure-temperature cases rather than selecting F11, F22 or F51 from nominal temperature alone.
- Application: identify main steam, reheat, feedwater or auxiliary service and whether pressure-seal construction is specified.
- Materials: provide body, bonnet, stem, wedge, seat, hardfacing, bolting and packing requirements with heat-treatment and welding controls.
- Operation: state differential pressure, required opening/closing time, handwheel/gear/actuator, torque margin and position feedback.
- Inspection: list QAP/ITP, MTC, heat-treatment records, NDE, pressure and leakage tests, dimensional inspection, spares and final data book.
Review the power plant valve procurement guide, power and energy application page and API 602 guide, then send the tender datasheet.
