UNOX DN100 (4″) 24V DC Electric Actuator Wafer Type
Designed for demanding industrial environments, this wafer-type butterfly valve uses a GGG40.3 ductile iron body with either an iron or stainless steel disc. The 24V DC electric actuator enables precise, energy-efficient flow control, which is ideal for compact automation setups and mobile facilities. An EPDM gasket provides reliable sealing from -10ºC to 110ºC, maintaining leak-free operation under pressure and with harsh media. Suitable for water and air applications, it balances durability with easy integration in automated systems.
UNOX DN80 (3″) 24V DC Electric Actuator Wafer Type
This 3-inch UNOX butterfly valve mirrors the 4-inch model’s emphasis on durability and precise low-voltage control. The 24V DC actuator delivers accurate modulation in compact automation systems, while the EPDM gasket ensures a leak-free seal across a wide temperature range. The GGG40.3 body provides solid corrosion resistance for long-term industrial use, making it a versatile choice for air and water lines with space constraints.
UNOX DN200 (8″) 24V DC Electric Actuator Wafer Type
For larger flow requirements, the 8-inch UNOX butterfly valve offers the same core benefits—durable GGG40.3 body, 24V DC actuation, and EPDM sealing. Its stainless steel or iron disc options provide corrosion resistance in challenging media, while the wide operational temperature range supports leak-free performance under pressure. This valve is well-suited for mid- to large-scale water and air distribution networks requiring reliable, automated control.
4” Butterfly Valve, Wafer, 200 Psi
This generic 4-inch wafer butterfly valve offers a robust ductile iron body rated for 200 PSI, with a 10-position handle and square stem. It provides strong mechanical performance for higher-pressure applications where simple manual or actuator-assisted control is adequate. While not listed with an electric actuator, it can be paired with compatible actuators in integrated systems, expanding its versatility for various pipeline configurations.
U.S. Solid Motorized Ball Valve- 1″ Stainless Steel
This 1-inch stainless steel, NSF-certified motorized ball valve provides reliable performance for drinking water lines. It supports 9–24V AC/DC operation with quick opening/closing and a long cycle life. The secure threading and compact footprint make it a practical choice for automation projects seeking rapid, dependable shut-off control in a simple ball-valve format that complements butterfly valves in mixed systems.
U.S. Solid Motorized Ball Valve- 1″ Stainless Steel Full Port
This model extends the capabilities of motorized ball valves with a full-port design, ensuring minimal flow resistance. It operates across a broad voltage range of 9–24V AC/DC and supports 3-wire, 1-point-control configurations with a positive break for reliable sealing when closed. It delivers rapid actuation under automated control, making it a strong companion piece for systems that integrate butterfly valves with ball valves for diverse flow management needs.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting an electric actuated butterfly valve, consider body material, disc choice, actuator type, and sealing compatibility. Ductile iron bodies (GGG40.3) paired with corrosion-resistant discs balance durability and cost, especially for water and air lines in industrial settings. EPDM gaskets deliver broad chemical compatibility and reliable sealing across a wide temperature window, which helps prevent leaks in pressurized systems.
Actuator specification drives performance. A 24V DC electric actuator provides predictable control with low energy consumption. In automation-heavy environments, ensure actuator torque and stroke meet your system’s valve size, pipe pressure, and required flow rate. Some users pair wafer valves with actuators or mounting kits to fit existing piping schemes or to upgrade from manual control.
Size compatibility is critical for minimizing pressure drops. Smaller DN80 and DN100 valves are adequate for localized control with compact equipment, while DN200 and larger valves suit higher flow demands. For large installations, verify actuator compatibility with control systems, sensors, and safety interlocks.
Sealing performance and temperature range affect reliability. EPDM gaskets sustain leak-free operation from cold to moderately hot media, but for aggressive chemicals or extreme temperatures alternative elastomers or metal seals may be needed. Always verify compatibility with the fluid media and pressure class (PSI) of your system.
Durability versus cost is a common trade-off. If your operation demands frequent cycling or exposure to corrosive media, prioritize valves with ductile iron bodies and stainless steel discs. For budget-conscious projects, wafer-style designs coupled with reliable actuation can still deliver precise control without overspending.
System integration considerations include electrical compatibility, mounting orientation, and space constraints. Low-voltage DC actuators simplify wiring and safety, but confirm the actuator’s mounting pattern matches your piping and control hardware. In mixed systems, combining butterfly valves with motorized ball valves can offer flexible control strategies across different segments of a distribution network.
Maintenance and service availability are practical factors. Choose manufacturers with readily available spare parts, gasket kits, and actuators, as well as clear installation documentation. This reduces downtime and extends the life of your automated valve network.
