PDF-documented product
Electric Ceramic Knife Gate Valve
The Lianggong product catalog identifies this item as Electric Ceramic Knife Gate Valve on PDF page 108. The page separates catalog-proven attributes from the project data that still requires technical confirmation.
- Valve type: Knife Gate Valve
- Material descriptor: Ceramic
- Actuation: Electric
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
Knife Gate Valve. This is the parent commercial route for category-level selection.
Catalog series
Knife Gate Valve. This is the source-series context printed in the recovered product catalog.
Evidence source
Recovered Lianggong English product catalog, PDF page 108; mapped product image AST-R1-0415.
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 | Knife Gate Valve | VERIFIED — PDF catalog label |
| Material descriptor | Ceramic | VERIFIED — PDF catalog label |
| Actuation | Electric | VERIFIED — PDF catalog label |
| Catalog source series | Knife Gate Valve | VERIFIED — PDF catalog section |
| Catalog source page | PDF page 108 | 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: Knife Gate Valve The PDF label identifies the valve type; it does not define the full configuration.
- Material descriptor: Ceramic This describes the catalog product identity, not a complete body, trim and wetted-parts schedule.
- Actuation: Electric The actuation route is named; sizing, power supply, accessories and control logic require confirmation.

Engineering review
How to specify the Electric Ceramic Knife 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
The catalog name includes Ceramic. Confirm the exact body grade, trim, seats/seals, wetted parts and required material records. Confirm end type, dimensional standard and mating interface.
Electric actuator data
Confirm power supply, control signal, enclosure/IP requirement, duty cycle, fail action, local controls and available torque margin.
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
Electric Ceramic Knife 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 Electric Ceramic Knife Gate Valve, its source series Knife Gate Valve, the mapped product image and the catalog-label fields shown in the data table.
Which data still requires confirmation?
The open fields include Design / construction, 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.
