The ARKA AS110FV 4-inch electric butterfly valve delivers motorized flow control for large-scale irrigation networks and industrial water systems with higher flow demands. Built from polyamide (PA) plastic with a flanged connection, this 4-inch valve handles flow rates up to 100 m³/h at a maximum working pressure of 10 bar. The integrated electric actuator provides automated open/close control, making the valve suitable for main line distribution, zone control, and large system manifolds. The all-plastic wetted path resists corrosion and weighs substantially less than comparable metal valves, reducing installation complexity for commercial users managing large infrastructure projects.
The 4-inch valve body is injection-molded from glass-reinforced polyamide (PA) plastic, formulated to maintain structural rigidity at the larger diameter while resisting deflection under pressure. The disc rotates on a stainless steel stem that passes through precision-machined bearing seats in the body, ensuring smooth operation and long service life. The larger bore size of the 4-inch valve provides a flow path that minimizes pressure drop at high flow rates, which is particularly important for main line applications where system pressure is a critical parameter.
The electric actuator mounted on the 4-inch valve is sized to deliver the torque required to operate the larger disc against maximum differential pressure. The actuator housing is constructed from durable plastic with a sealed enclosure designed for outdoor exposure. Internal limit switches stop the motor at the fully open and fully closed positions, and a visual position indicator on the actuator top shows the valve status at a glance. The actuator connects via a waterproof cable assembly, and voltage and control options can be specified to match site requirements.
The valve features a flanged connection compatible with standard 4-inch flange patterns. The wafer-style body design allows installation between two pipe flanges using through-bolts. A resilient rubber seat ring molded into the body bore provides a bubble-tight seal when the disc is closed, and the seat material is selected for compatibility with water service conditions. The flat flange face accommodates standard gasket materials for a reliable pipe joint.

In large agricultural irrigation systems covering hundreds of acres, the 4-inch electric butterfly valve serves as a main line control valve, managing water flow from the pump station or source to distribution manifolds and zone valves. The 100 m³/h flow capacity supports extensive drip, sprinkler, or pivot irrigation networks. Electric actuation allows system operators to open and close main lines remotely, either on a scheduled basis or in response to system pressure and demand signals, reducing the need for on-site manual valve operation.
Industrial facilities with high-volume water requirements deploy 4-inch electric butterfly valves in distribution mains, cooling water supply lines, and wastewater collection systems. The PA plastic construction is well-suited for water treatment plants, where chemical dosing and varying water chemistry can accelerate corrosion in metal valves. Commercial users in manufacturing, power generation, and food processing integrate these valves into automated control systems for efficient flow management and reduced maintenance overhead.
Municipal water departments, golf course irrigation systems, and large commercial landscape projects use 4-inch electric butterfly valves at key distribution points throughout their networks. The electric actuator allows integration with central control systems, enabling automated scheduling, flow monitoring, and rapid response to system alarms. The lightweight plastic construction simplifies installation in valve vaults and underground utility structures where working space is limited.
Install the 4-inch butterfly valve between two properly aligned pipe flanges, using appropriate gaskets and through-bolts. Ensure the pipe flanges are parallel and that the valve body is not subjected to piping stress; use pipe supports on both sides of the valve to carry the weight of the pipe and water. The valve may be installed in horizontal or vertical pipe runs. For horizontal installations, position the actuator on top to prevent water ingress. Tighten flange bolts evenly in a cross pattern to achieve uniform gasket compression. Verify that the valve disc rotates freely through its full 90-degree travel before connecting the actuator power supply.
Connect the actuator cable to the control panel or irrigation controller according to the provided wiring diagram. Observe correct polarity for DC-powered actuators. The actuator typically requires connections for power supply, open/close control signals, and optional position feedback. For systems using a PLC or SCADA controller, confirm the signal type (dry contact, voltage, or current loop) matches the actuator input specifications. Ground all electrical components in accordance with local electrical codes.
Plastic butterfly valves require minimal maintenance compared to metal valves. Recommended periodic checks include: inspecting flange connections for leaks, verifying actuator mounting bolts are tight, confirming the valve stem seal shows no signs of weeping, and testing full open/close cycles to ensure smooth operation. The rubber seat ring will wear over time and may need replacement depending on cycle frequency and water conditions. Spare parts, including seat rings and stem seals, are available for service kits.
The manufacturer specifies a maximum flow rate of 100 m³/h. Actual flow in a given installation depends on available pressure, pipe diameter, and system friction losses. For applications requiring flow rates near the maximum, verify that system pressure is sufficient to overcome the valve and piping pressure drop at the desired flow rate.
Yes, the valve is rated for 10 bar maximum working pressure, which covers most agricultural and light industrial irrigation main line applications. For systems with operating pressures near or above 10 bar, consider metal-bodied valves with higher pressure ratings. Always verify system pressure against the valve rating before installation.
The 4-inch butterfly valve features a wafer-style flange compatible with standard 4-inch flange patterns. Bolt size is M16. Confirm that your pipe flanges match the bolt circle diameter and bolt count before ordering. Our technical team can provide flange dimension drawings to verify compatibility with your existing piping.
The actuator housing is designed with a sealed enclosure suitable for outdoor installation and exposure to rain and sprinkler spray. It is not designed for continuous submersion. For installations in flood-prone areas or valve pits that may fill with water, mount the actuator above the expected water level or provide additional protection.
Yes, OEM services and bulk pricing are available for commercial procurement and enterprise customers. Custom options include actuator voltage selection, modified flange specifications, private labeling, and custom packaging. For large projects, our technical team can assist with valve sizing, system layout review, and delivery scheduling.
