This polyurethane-lined knife gate valve is supplied with a cast-iron body, with stainless-steel body options available. The gate moves relative to the selected sealing arrangement to provide the specified isolation duty. Confirm the internal groove and seal details on the approved sectional drawing rather than inferring them from the product name. Suitability for solids and chemicals depends on the actual materials and operating conditions.
This polyurethane-lined knife gate valve has a cast-iron body, with stainless-steel body options available for inquiry. Larger sizes are limited to PN10; smaller configurations can be supplied as PN16. The applicable size boundary and actual order rating must be confirmed in the approved specification.
Product Overview
A sliding gate provides the isolation movement, while the selected polyurethane sealing arrangement forms part of the wetted configuration. Body material and pressure selection must be stated for the actual size. The product name alone does not establish chemical compatibility, abrasive-service life or an internal groove detail.
Selection and Ordering Notes
- Specify nominal size and request confirmation of the applicable PN10 or PN16 configuration.
- Choose the cast-iron body or request the available stainless-steel alternative and exact grade.
- Describe solids, fluid composition, concentration and operating conditions for the proposed lining and sealing arrangement.
- Confirm the gate material, connection drilling, drive, installation orientation and approved sectional drawing.
