Why Its a Smart Choice

Secure mounting design: The lugged and tapped configuration allows bolting from one side only, making it easy to isolate or remove the valve without dismantling the entire pipeline.
Robust and corrosion-resistant: The stainless steel disc and EPDM liner combination ensures long-lasting performance even in demanding service conditions.
Automation ready: ISO 5211 compatibility allows direct fitting of electric or pneumatic actuators, offering a simple upgrade path from manual control.
Reliable sealing: EPDM provides strong resistance to water, mild chemicals, and air, maintaining tight shutoff and smooth operation under pressure.
Low maintenance: The durable coating and quality internal materials minimise wear, corrosion, and downtime across service life.

Installation and Application Tips

• Verify ANSI 150 flange compatibility before installation to ensure bolt pattern alignment and proper sealing.
• Use uniform bolt torque to prevent body distortion and ensure optimal sealing pressure.
• Confirm that EPDM liner material suits the process medium, excellent for water, air, and mild chemicals, but not suitable for hydrocarbons or strong solvents.
• Align pipework properly and support it well to prevent mechanical strain on the valve body or flange lugs.
• If automating, ensure actuator torque ratings match valve size and pressure requirements.
• Regularly inspect liner condition and clean internal surfaces during maintenance intervals to maintain full sealing performance.

The Lugged and Tapped Butterfly Valve with Stainless Steel Disc and EPDM Liner ANSI 150 offers a dependable, cost-effective solution for fluid control in industrial and commercial systems. Combining rugged construction, precision sealing, and easy automation capability, its built to deliver consistent performance and longevity in water treatment, HVAC, and general process applications.
