ANSI 150 compatibility: Designed for seamless installation into ANSI 150 flange systems without the need for adaptors or modifications.

Installation and Application Tips

• Verify that flange bolt patterns and gaskets match ANSI 150 standards before installation.
• Apply even torque across all bolts to maintain alignment and proper sealing pressure.
• Ensure the NBR liner is compatible with your process fluid, its ideal for water, air, and mild chemicals but not suitable for strong solvents or hydrocarbons.
• Support and align pipework correctly to prevent stress or distortion on the valve body and flanges.
• Check actuator torque compatibility before automation to ensure reliable operation.
• Regularly inspect the liner and disc for wear or damage to sustain peak sealing performance.

The Lugged and Tapped Butterfly Valve with Stainless Steel Disc and NBR Liner ANSI 150 is a durable, versatile, and cost-effective solution for fluid control in industrial and commercial systems. Its corrosion-resistant materials, reliable sealing, and easy installation make it a trusted choice for engineers and maintenance teams seeking consistent performance and long-term dependability.
