Installation and Application Tips

• Check that the valves flange compatibility matches your system standard (PN, ANSI, or Table type).
• Use appropriate fasteners and torque evenly during installation to maintain a uniform seal and prevent body distortion.
• For automation, confirm actuator torque compatibility, especially for larger valve sizes.
• Ensure the NBR liner is suitable for your process media, ideal for water, air, and mild chemicals, but not recommended for strong solvents or acids.
• Keep the valve within its rated temperature and pressure limits to maintain reliable performance.
• When servicing, the wafer design and ISO 5211 mount simplify removal and maintenance without full line disassembly.
