The ARKA AS90FV 3-inch electric butterfly valve provides motorized flow control for irrigation and industrial water systems. Constructed from polyamide (PA) plastic with a flanged connection, this valve combines corrosion-resistant materials with electric actuation to support automated flow regulation. The valve body features a wafer-style flange design compatible with standard 3-inch piping, and the integrated electric actuator enables remote open/close control. With a maximum working pressure of 10 bar and flow capacity up to 50 m³/h, this unit serves commercial users requiring reliable, low-maintenance flow control in water distribution networks.
The valve body is injection-molded from glass-filled polyamide (PA) plastic, engineered for dimensional stability and chemical resistance in water service applications. The disc, also PA plastic, rotates 90 degrees within the body to modulate flow from fully open to fully closed. A rubber seal ring seated in the body bore provides a bubble-tight shutoff when the disc is in the closed position. The plastic construction eliminates corrosion concerns associated with metal valves in outdoor and water-exposed environments, and reduces overall weight compared to cast iron or stainless steel equivalents.
The electric actuator mounts directly on top of the valve stem and provides motorized 90-degree rotation. The actuator housing is constructed from durable plastic with an IP-rated enclosure suitable for outdoor installation. A power cable with waterproof connector supplies voltage to the motor and position feedback circuit. The actuator includes limit switches that cut power at fully open and fully closed positions, preventing motor overload. Actuator voltage options can be specified at the time of order to match site electrical requirements.
The valve body features a flanged connection with bolt holes sized for M16 fasteners, compatible with standard 3-inch flange patterns. The wafer-style design allows the valve to be sandwiched between two pipe flanges using through-bolts, simplifying installation and removal. The flat face flange design is suitable for use with standard flat-face or raised-face flange gaskets, depending on system pressure requirements.

In automated irrigation systems, the 3-inch electric butterfly valve controls water flow to individual zones or sections of a farm, greenhouse, or landscape irrigation network. The electric actuator interfaces with irrigation controllers, timers, or SCADA systems to schedule watering cycles and manage water distribution across multiple zones. This level of automation reduces labor requirements for commercial farming operations and supports precision irrigation strategies that optimize water usage.
Industrial facilities integrate these valves into water treatment plants, cooling tower systems, and process water loops where automated flow control is required. The PA plastic construction resists corrosion from treated water and mild chemical solutions, making the valve suitable for applications where metal valves would degrade over time. Commercial users in the food and beverage, pharmaceutical, and textile industries deploy these valves in non-critical process lines where cost-effective automated control is needed.
In aquaculture and aquaponics facilities, the electric butterfly valve manages water flow between tanks, filters, and biofiltration systems. The all-plastic wetted surfaces do not leach metallic ions into the water, which is important for maintaining water quality in fish and plant cultivation systems. The electric actuation allows facility managers to remotely adjust flow rates from a central control panel, reducing the need for manual valve operation across large facilities.
Install the valve between two pipe flanges using appropriate gaskets and M16 through-bolts. Ensure the valve disc can rotate freely without contacting the pipe interior. The valve may be installed in horizontal or vertical pipe runs, though horizontal installation with the actuator positioned on top is recommended for best actuator drainage and seal life. Tighten flange bolts in a crisscross pattern to ensure even gasket compression and prevent leaks. Connect the actuator power cable to the control circuit according to the wiring diagram, observing correct polarity for DC-powered models.
The electric actuator is designed for intermittent duty cycling, typical of on/off flow control applications. For continuous modulating service, verify the actuator duty rating with the manufacturer. The valve should not be used as a throttling valve for extended periods at intermediate positions unless specified as a modulating actuator model. Before performing maintenance, isolate the valve from the pipeline and disconnect electrical power to prevent accidental actuation.
The electric actuator is available in multiple voltage configurations to suit different installation requirements, including common DC and AC options. Specify your required voltage at the time of order to ensure the valve matches your control system. Contact our sales team for a complete list of available voltage and control options.
Yes, the PA plastic valve body is UV-resistant and designed for outdoor use. The electric actuator housing is rated for outdoor installation with appropriate weather protection. For installations in areas with heavy rainfall or submersion risk, additional protective enclosures may be advisable.
The PA plastic and rubber seal materials are compatible with clean water, treated wastewater, and mild chemical solutions. The valve is not recommended for use with strong acids, strong bases, solvents, or hydrocarbon fluids without verifying chemical compatibility. Consult our technical team for compatibility assessment of specific fluids.
Plastic butterfly valves offer several advantages for water service applications: they weigh significantly less, reducing installation labor and pipe stress; they resist corrosion from water and many chemicals; and they typically cost less than metal equivalents. Metal valves are preferred for higher pressure ratings, higher temperature applications, and systems with significant water hammer or mechanical stress.
Yes, OEM and custom specification services are available for commercial procurement orders. This includes custom actuator voltage, modified flange patterns, private labeling, and custom packaging. Minimum order quantities apply for custom configurations. Contact our sales team to discuss your project requirements.
