FLOW CONTROL / Steel industries
Steelworks gas and air systems use different devices for regulating flow and for isolating a line. The Prestige catalogue includes blind and goggle designs alongside dampers.
Discuss your application
Steelworks gas and air systems combine flow regulation with line-isolation duties that require different equipment and operating procedures. Start by identifying the gas stream, temperature, dust content and isolation objective so a blind or goggle valve and a damper can be reviewed for their respective functions.
A swing blind or goggle design provides a physical plate arrangement for a defined line-isolation duty. Review the catalogue option with the plant's isolation sequence, connection, space and pressure-temperature conditions; the assembly must be confirmed within the site's operating and maintenance procedure.
The enclosed sliding blind-valve listing offers another configuration to discuss where the layout calls for that arrangement. Provide the gas composition, installation drawing and operating requirements, then request confirmation of enclosure behaviour, sealing provisions and actuation for the proposed assembly.
A multi-blade or butterfly damper may be reviewed for an appropriate gas-flow duty. Specify the required flow range, pressure difference, temperature, duct geometry and allowable leakage so regulation performance can be considered separately from physical blind isolation.
SELECTION / LOOK BEYOND LINE SIZE
A damper used to adjust airflow does not automatically fulfil a plant's blind-isolation requirement. Define the purpose of each device and the required leakage or isolation criteria in the enquiry.
Dust, moisture, composition and temperature vary between streams and operating stages. Describe the individual line and its normal and maximum conditions instead of specifying only a steelworks-gas application.
The arrangement must fit the site's isolation, depressurisation, purging and interlocking requirements. Provide that project specification for review; a product page is not an operating procedure for a gas system.
Body, trim, seals and actuation need to work together under your service conditions.
Review the body, plate or blades, seals and any flexible components against the actual temperature, gas and dust conditions. A nominal diameter does not establish the operating limit or sealing behaviour of a gas-handling assembly.
A swing or sliding plate needs space for its movement as well as access for operation and servicing. Include surrounding pipework and structure in the drawing so the proposed configuration can be reviewed before installation.
State manual or powered operation, site utilities and the required indication of position or completed movement. Confirm any interlocking or enclosure requirements for the quoted configuration; these features should not be inferred from the design name.
Explore these catalogue configurations, compare their specifications and share your operating conditions with our team.
Discuss blind or goggle isolation configurations.
Size Range: 150mm to 600mm. Pressure Rating: PN2.5/ PN6.
Review an enclosed blind valve configuration.
Size Range: 300mm to 2500mm. Pressure Rating: PN2.5/ PN6.
Explore gas or air regulation using a damper.
Size Range: 40mm to 1800mm. Operation: Worm Gear/ Electric Actuator.
Review for blind or goggle line isolation.
Size Range: 150mm to 600mm. Pressure Rating: PN2.5/ PN6.
Review for air or gas-flow regulation.
Size Range: 40mm to 1800mm. Operation: Worm Gear/ Electric Actuator.
Final selection depends on the complete valve configuration, fluid compatibility and operating duty. Project-specific approvals and limits are confirmed with the quotation.
BEFORE YOU SPECIFY / PRACTICAL ANSWERS
Questions worth discussing for your steel industries application.
Ask our teamTheir functions can differ. A damper may regulate flow or provide a stated shut-off performance, while a blind arrangement creates a physical line-isolation configuration. The plant engineer should define the required isolation method and confirm the assembly against it.
No. Ask for the quoted construction, sealing provisions and operating arrangement to be reviewed against the gas conditions and project requirement. The enclosure description alone does not establish a universal leakage rating or operating sequence.
Send the gas composition, dust content, temperature and pressure range, dimensions and intended function. Include the line drawing, operating sequence, interlock and documentation requirements so the discussion covers the complete installation instead of just a replacement diameter.
Share the medium, duty, size, connections and operating conditions.
