The portfolio includes a standard uni-directional design as well as a bi-directional soft-seated configuration. The optimal selection depends on the direction of differential pressure and your specific sealing performance requirements.

Select Construction
The gate travels across the flow path to shut off flow. AVM designs feature bonneted or bonnetless configurations, rising or non-rising stems, and a variety of body styles.
Define the sealing direction
The standard configuration is engineered for unidirectional shut-off, with a bidirectional resilient-seated design also available. Through-conduit models as well as rubber, polyurethane, or ceramic linings are designed to meet specialized operational requirements and must be specified separately.
Distinguishing Fibres from Abrasion
The knife gate valve family covers a wide range of applications. Selecting a valve for fibrous effluents requires a completely different approach than one engineered for abrasive mineral slurry.

| Body and blade | Ductile iron, carbon steel, or stainless steel depending on the design. Gate stainless steel grade selected based on corrosion and abrasion requirements. |
| Seats and End Connections | EPDM, NBR, FKM, PTFE, or metal seated depending on the version. Wafer, lug, or single-flange body style depending on the configuration. |
| Design Standard | MSS SP-81 as specified in the brochure. Test conditions and sealing performance levels are to be confirmed upon quotation. |
Custom configurations for higher pressure ratings are available upon request. Please note that PN10 does not apply across the entire product line, and flange drilling patterns should not be confused with the valve's maximum allowable working pressure.
