Frequently Asked Questions

Actuated butterfly valves offer advantages such as synchronisation of multiple line valves, remote isolation, torque required for opening larger butterfly valves, and security measures to prevent misuse.
The body materials can be GJS500-7 Ductile Iron Rilsan Coated or CF8M Stainless Steel. The disc materials are CF8M Stainless Steel, and the seat materials include EPDM, NBR Buna, Hypalon, Viton, Silicone, High Temperature, Polyisoprene, and Epichloridine.
The actuated functions include pneumatic, electric, de-clutchable gear, fail-safe, spring return, battery backup, and double-acting.
Actuated butterfly valves can be used for potable/waste water, cooling systems, oil, gases, air, corrosive chemicals, pharmaceuticals, petrochemicals, food and beverage, and various industrial processes.
Wafer pattern valves are designed for installation between two flanges at intermediate points within the process pipeline, while lugged pattern valves use threaded lugs for precise self-centering capabilities and are commonly used as dead-end service valves or for maintenance purposes.
PTFE lining is used in valves intended for highly corrosive environments or high-service temperatures. It provides excellent chemical resistance and a clean, FDA-approved contact surface.
Yes, Actuation Valve offers actuated butterfly valves suitable for marine applications, featuring materials like B148 C9500 Aluminium Bronze and EPDM seats suitable for seawater, cooling systems, desalination, and other marine environments. The 80WM580 & 80LM580 in particular are the most common.
The size ranges vary depending on the valve type, but they generally span from DN32 (1 1/4") to DN1600 (64").
Yes, Actuation Valve can provide various certifications, including witness testing, 3.1 certification, and standard pressure tests. Additional certifications can be arranged upon request.
Yes, Actuation Valve offers sustainable spares and replacement parts for ongoing maintenance schedules.
Depending on the valve, actuator and process type pressure ratings range from PN10, PN16, PN40., ANSI 150 and ANSI 300.
