View Product CatalogForex Valves is based in Ahmedabad, Gujarat, India, and offers industrial valve solutions for pipeline applications. A cast steel knife edge gate valve is designed for flow isolation in applications where a knife-edge gate design is suitable for the process medium and operating conditions.
Selecting the appropriate valve requires consideration of the pipeline size, operating pressure, temperature, process medium, material compatibility, end connections and installation requirements. The exact valve configuration should be confirmed against the applicable product documentation.
A knife edge gate valve uses a thin gate with an edge designed to move through the flow passage and help isolate the pipeline. Depending on its design and construction, this type of valve may be considered for services involving fluids that can contain suspended solids or fibrous material.
The suitability of a knife edge gate valve depends on the medium, solids characteristics, pressure, temperature and the valve's specific design. Not every knife gate valve is suitable for every slurry or industrial process.
The valve's construction and material selection should match the application requirements. Relevant components may include the valve body, knife-edge gate, stem, seat and sealing arrangement.
Before selecting a cast steel knife edge gate valve, verify:
Nominal valve size and required flow passage.
Operating pressure and temperature limits.
Fluid properties and suspended-solids characteristics.
Cast steel grade and compatibility with the process medium.
Seat material and sealing arrangement for the intended duty.
End connections, installation dimensions and operating method.
Knife edge gate valves may be considered for industrial services where their gate design is appropriate, including selected applications involving:
Provide details of the fluid, slurry or material being handled, including relevant solids characteristics.
Specify the required nominal size and installation dimensions.
Share the normal and maximum operating pressure and temperature.
Confirm that the body, gate, seat and sealing materials are appropriate for the process medium.
Identify the required connection type and any installation constraints.
Explain the required isolation performance and any process-specific leakage requirements.
Identify applicable standards, inspection requirements and testing documentation.
