Double Flanged Gate Valve
The Double Flanged Gate Valve is a bolted-end isolation valve for pipelines where maintenance access, flange compatibility and dependable full-open or full-closed operation matter. Vcore Valve confirms the final configuration from project data instead of publishing fixed pressure, temperature, leakage or standard claims without a selected model.
Double Flanged Gate Valve Selection Notes
A Double Flanged Gate Valve should match the pipeline flange standard, face-to-face requirement, installation space and operation torque before production. Vcore Valve confirms these points from project documents.
| Selection item | Engineering check |
|---|---|
| Flange connection | Flange drilling and face-to-face dimensions confirmed against project piping standard. |
| Wedge and seat | Resilient, metal seated or hard-faced options selected only from confirmed model data. |
| Stem arrangement | Rising stem or non-rising stem chosen by installation space and operator visibility. |
| Operator | Handwheel, gearbox or actuator selected by torque, valve size and site access. |
| Marking and coating | Nameplate, coating and tag requirements matched to project documents. |
Product Configuration
The configuration below helps engineers define the valve without publishing unconfirmed size range, pressure class, temperature range, leakage class or standard compliance.
| Configuration area | How Vcore Valve confirms it |
|---|---|
| Body pattern | Double flanged body for removable bolted pipeline installation. |
| Wedge design | Selected according to shutoff expectation, material and maintenance plan. |
| Flange standard | Confirmed from project piping class before manufacturing. |
| Operation method | Manual, gear or actuator option selected by torque and site access. |
| Quality documents | Inspection records and certificates aligned with purchase order. |
Technical Specification Checklist
| Item to confirm | Why it matters |
|---|---|
| Media and concentration | Determines body, trim, seat and packing compatibility. |
| Operating and design conditions | Prevents under-selection for pressure, temperature or cycling duty. |
| Pipe connection and installation space | Controls flange, face-to-face, stem and operator arrangement. |
| Shutoff expectation | Keeps the valve selected for full-open or full-closed isolation service. |
| Testing and certificates | Keeps inspection scope aligned with the purchase order and QA plan. |
Application Guidance
Typical applications include water treatment, utility distribution, industrial cooling water, oil handling, general process isolation and pipeline sections that need removable flanged connections.
Comparison With Similar Valve Types
| Valve type | Best-fit use |
|---|---|
| Double Flanged Gate Valve | Bolted installation and removable pipeline isolation. |
| Wafer valve | Compact and lighter, but not equivalent to a full flanged gate valve. |
| Knife gate valve | Better for slurry or solids handling but different sealing and pressure design. |
Pre-Order Checklist
| Checklist point | Required customer input |
|---|---|
| Line data | Nominal size, flange standard and face-to-face requirement. |
| Service data | Media, operating pressure, operating temperature and cleaning method. |
| Materials | Preferred body, trim, seat, packing and bolting material if specified. |
| Operation | Handwheel, gearbox, pneumatic, electric or other actuator requirement. |
| Quality control | Inspection hold points, test records, certificates and export packing requirement. |

Standards and Document Review
Vcore Valve confirms the exact standard name, edition and test scope from the purchase documents. Buyers can use the ASME B16.34 standard page as an external reference when that standard is specified, but final compliance must match the selected Double Flanged Gate Valve model and datasheet.
FAQ
Where is a Double Flanged Gate Valve commonly used?
It is commonly used for pipeline isolation in water, utility and industrial process systems that require bolted flange installation.
Can flange standards be customized?
Flange drilling and dimensions can be matched to the selected model and project standard after confirmation.
Is it used for flow control?
It is normally used fully open or fully closed; a globe or control valve is usually better for regular flow regulation.
