UNOX DN100 Butterfly Valve (4″)
The UNOX DN100 Butterfly Valve combines a GGG40.3 ductile iron body with an iron or stainless steel disc, delivering high durability for continuous industrial use. A 24V DC electric actuator enables precise, low-voltage control ideal for compact automation systems and mobile setups. An EPDM gasket provides reliable shutoff across -10ºC to 110ºC, maintaining a leak-free seal under pressure and harsh media.
Key features include:
– Maximum durability with a corrosion-resistant body and disc options.
– Low-voltage, precise control via a 24V DC actuator.
– Reliable sealing with an EPDM gasket for wide temperature ranges.
UNOX DN80 Butterfly Valve (3″)
This 3″ UNOX butterfly valve is built for dependable performance in water and air lines. The 24V DC actuator supports precise flow control in compact automation setups. The GGG40.3 body maintains structural integrity and corrosion resistance, while EPDM sealing ensures leak-free operation across temperatures from -10ºC to 110ºC.
Highlights:
– Durable ductile iron body with a robust disc option.
– Energy-efficient 24V DC actuator for accurate positioning.
– EPDM gasket for solid sealing under varying media and temperatures.
UNOX DN200 Butterfly Valve (8″)
The large-diameter UNOX 8″ butterfly valve focuses on heavy-duty flow control for water and air lines in industrial settings. It features a GGG40.3 body and either iron or stainless steel disc options, with a 24V DC actuated control system for precise, safe operation. The EPDM gasket provides reliable sealing within a wide temperature range, maintaining performance under pressure and across media types.
Considerations include:
– Large valve size for higher flow handling and pressure tolerance.
– Durable construction suitable for prolonged industrial use.
– Consistent sealing with a temperature-tolerant EPDM gasket.
4” Butterfly Valve, Wafer, 200 Psi
This 4” wafer-style butterfly valve is rated for 200 psi and uses a ductile iron body with a square stem and 10-position handle. While not inherently motorized, the wafer design pairs well with compatible electric actuators for automated control in HVAC and industrial pipelines. The robust construction supports reliable operation under varying pressures.
BACOENG 2 Way Motorized Ball Valve
Although a ball valve rather than a butterfly, this model demonstrates actuator-driven flow control in a common piping size. It features a stainless steel body, 1″ DN25 port, and AC 110-230V control, with a full bore design for minimal pressure loss. The actuator integrates two-wire control plus a spring return for safety when power is interrupted.
Propensity guides include:
– Full port stainless steel valve for clean, predictable flow.
– Wide voltage compatibility for diverse electrical environments.
– Safe design with a spring return option and reliable actuation.
Buying Guide: Key Considerations for Electric Actuated Butterfly Valves
To select the best electric actuated butterfly valve for your application, consider these factors from different perspectives:
- Valve size and media compatibility: Choose a valve size that matches your pipe diameter and ensure the disc and seals are compatible with your media, whether water, air, or chemical-laden fluids. For larger systems, DN200 or larger valves accommodate higher flow and pressure.
- Actuator type and control requirements: 24V DC actuators provide energy-efficient, precise control in compact installations, while AC actuators (110-230V) are common in industrial settings. Confirm required stroke time, feedback signals (position sensing), and safety features like limit switches or spring return.
- Valve body material and corrosion resistance: Ductile iron bodies with EPDM seals perform well in many water applications; stainless steel options are preferred for aggressive media or high hygiene standards. Gasket materials should tolerate the operating temperature range.
- Sealing performance and temperature range: Look for leak-tight operation at your system’s pressure and temperature. EPDM is common for water applications, whereas FKM (Viton) may be needed for oils or solvents.
- Installation orientation and mounting: Wafer-type valves are compact and widely compatible with flanged or wafer connections. Ensure actuator mount compatibility and consider space for actuator operation and maintenance access.
- Reliability and maintenance: Manufacturers offering robust bodies, corrosion-resistant discs, and durable seals typically provide longer service intervals. Review actuator service life, spare parts availability, and warranty terms.
- Compliance and certifications: For drinking water or medical applications, ensure NSF/ANSI certifications or other regional compliance to meet safety and hygiene standards.
- Cost of ownership: While initial price matters, factor in energy use from actuators, maintenance costs, and potential downtime for replacements or repairs when evaluating total cost of ownership.
In summary, electric actuated butterfly valves offer a balance of durability, precise automation, and compact design. By assessing valve size, material compatibility, actuator features, and maintenance expectations, you can select a valve that reliably controls flow while meeting your system’s efficiency and safety requirements.
