Our electric 3-way ball valves feature adjustable fluid flow direction, providing flexible flow control solutions. Achieve efficient fluid distribution and conversion through automated operation. Learn more about the features and applications of our electric 3-way ball valves.

Electric Gate Valves Series

Pioneers in the industry, COVNA offer electric knife gate valve, basalt line gate valve, resilient seated gate valve, resilient seated sluice valve and industrial edge gate valve. Superior grade, high efficiency, low power consumption, modular design and weather resistant best describe the quality of Motorized Knife Gate. Valves are available in wafer or lug style, as well as with cast iron bodies or stainless steel bodie.

Electric Globe Valves Series

Globe valves are ideal for throttling service. Their flow characteristics permit accurate and repeatable flow control. Stainless steel 316 globe valve has a bolted bonnet, non-rising stem, and flanged connections on both ends, and is used to control flow (throttling) in a pipeline or water plumbing system.

The valve body is constructed of stainless steel 316 for higher strength and greater corrosion resistance. The valve has a bolted bonnet for tight assembly and reduced risk of leakage, and flanged end connections for bolting to compatible pipe flanges. The stem/wedge connection meets the API 600 Pull test.

About Covna Electric Valve

Covna Electric Valves: Precision Automation for Industrial Fluid Control
Covna electric valves are high-performance electromechanical devices designed to regulate liquid, gas, or steam flow in industrial systems. Combining durable materials (stainless steel, brass, or corrosion-resistant PVC) with advanced motor or solenoid actuators, these valves enable precise on/off control or proportional modulation for applications like water treatment, HVAC, chemical processing, and oil/gas pipelines. Key advantages include energy efficiency, IP67 waterproof ratings for harsh environments, and seamless integration with automation systems (PLC, IoT, or Modbus protocols). Covna valves are CE, RoHS, and ISO 9001 certified, ensuring reliability and compliance for global industries seeking robust, smart fluid control solutions.

How Covna Electric Valves Work

Covna electric valves operate through an electric actuator (motor or solenoid) that converts electrical signals into precise mechanical motion. When a control signal (e.g., 24V DC, 4–20mA, or digital command) is received, the actuator adjusts the valve’s opening, either fully opening/closing the flow path or modulating it proportionally. Motor-driven actuators enable gradual adjustments for precise flow control, while solenoid actuators provide instant on/off action. Built with corrosion-resistant materials and sealed against dust/water (IP67), Covna valves ensure reliable performance in demanding environments, seamlessly integrating with automation systems like PLCs or IoT platforms for smart industrial operations.
