PDF-documented product
Bevel Gear Slab Gate Valve
The Lianggong product catalog identifies this item as Bevel Gear Slab Gate Valve on PDF page 111. The page separates catalog-proven attributes from the project data that still requires technical confirmation.
- Valve type: Gate Valve
- Design / construction: Slab gate
- Actuation: Bevel gear
Product identity
What this catalog record owns
This page represents one documented catalog identity. It does not replace the parent product category and it does not claim an unverified model, rating or project history.
Product family
Gate Valve. This is the parent commercial route for category-level selection.
Catalog series
Oil Field Valve. This is the source-series context printed in the recovered product catalog.
Evidence source
Recovered Lianggong English product catalog, PDF page 111; mapped product image AST-R1-0447.
Catalog evidence
Catalog-documented product data
Only fields stated by the PDF catalog label are shown as product data. A descriptive term such as high pressure, large diameter or ASME does not create a numeric rating, orderable range or certification claim.
| Field | Catalog-documented value | Evidence status |
|---|---|---|
| Valve type | Gate Valve | VERIFIED — PDF catalog label |
| Design / construction | Slab gate | VERIFIED — PDF catalog label |
| Actuation | Bevel gear | VERIFIED — PDF catalog label |
| Catalog source series | Oil Field Valve | VERIFIED — PDF catalog section |
| Catalog source page | PDF page 111 | VERIFIED — recovered PDF mapping |
Important: values not shown in this table are intentionally unconfirmed. They must be resolved on the offered datasheet and approved order drawing.
Evidence boundary
Known facts and open configuration fields
The PDF proves the product label and mapped appearance. It does not by itself prove a complete bill of materials, operating envelope or order-ready model.
Confirmed by the catalog
- Valve type: Gate Valve The PDF label identifies the valve type; it does not define the full configuration.
- Design / construction: Slab gate This is a catalog-name construction descriptor; detailed geometry requires an approved drawing.
- Actuation: Bevel gear The actuation route is named; sizing, power supply, accessories and control logic require confirmation.

Engineering review
How to specify the Bevel Gear Slab Gate Valve
A usable inquiry connects the catalog identity to the real duty. The following inputs determine whether the offered configuration can be selected and documented safely.
Valve duty
State whether the valve is for isolation, throttling, bypass or another defined function, together with cycle frequency and required shutoff behavior.
Operating envelope
Provide nominal size, pressure class, operating/design pressure, minimum/maximum temperature and any transient or vacuum cases.
Materials and connection
Provide body, trim, seat/seal and wetted-parts requirements based on the actual fluid, temperature and corrosion/erosion conditions. Confirm end type, dimensional standard and mating interface.
Operating arrangement
Confirm operating torque, access and duty-cycle requirements for the catalog-described bevel gear arrangement.
Inspection and documents
List drawing, datasheet, material certificate, pressure/leakage test, inspection, marking and third-party witness requirements for the offered configuration.
Application boundary
Match the catalog identity to the real service
Product names are useful starting points, but final suitability depends on the complete operating case and the exact configuration offered for review.
Service medium
The PDF label does not assign a medium. Provide fluid composition, concentration, solids, corrosion/erosion risks and cleaning requirements.
Industry and system
Identify the plant, equipment and piping function. Industry naming alone is not enough to determine valve design or materials.
Installation boundary
Confirm orientation, flow direction, piping loads, available space, access, ambient conditions, maintenance method and mating interfaces.
Visual evidence
Mapped product images from the catalog
These images support product identity and appearance only. They do not establish dimensions, material grade, pressure rating, certification or the final supplied configuration.

Buyer questions
Bevel Gear Slab Gate Valve FAQ
These answers preserve the line between documented catalog evidence and project-specific selection.
What does the PDF catalog confirm for this product?
It confirms the product name Bevel Gear Slab Gate Valve, its source series Oil Field Valve, the mapped product image and the catalog-label fields shown in the data table.
Which data still requires confirmation?
The open fields include Material descriptor, Pressure descriptor, Size descriptor, Standard descriptor, Connection, Service / medium. Temperature, detailed materials, testing, dimensions, certification, price and lead time also require the offered product documents.
Can the catalog image be used as a final dimensional reference?
No. The image confirms catalog identity and appearance context only. Fabrication, installation and procurement must use the approved datasheet and order drawing.
What should be included in the RFQ?
Send the required valve function, medium, size, pressure, temperature, connection, materials, actuation, quantity, document list and applicable inspection or witness requirements.
