The electric V-type ball valve's core is a ball with a V-shaped channel, driven by an electric actuator to rotate 90° to achieve media flow control and linear regulation. It features a high turntable ratio of 100:1 to 300:1 and equal percentage flow characteristics. Structurally, it is divided into floating, fixed, and resilient types. The floating type is suitable for medium and low-pressure sealing, the fixed type is suitable for high-pressure and large-diameter applications, and the resilient type is designed specifically for high-temperature and high-pressure applications. The valve body is made of stainless steel, carbon steel, etc., with nominal diameters from DN25 to 400 mm and operating temperatures ranging from -40℃ to 250℃. It conforms to industrial standards such as GB/T12237 and ASME B16.34. The V-shaped notch can shear media containing fibers or particles. Sealing methods include metal hard seals and PTFE soft seals. It supports flange and wafer connections and integrates automatic control and remote operation functions.
Its core design features include:
V-shaped shearing port: A shearing action is created between the ball and the valve seat, effectively cutting fibers, small particles, or slurry to prevent clogging.
Compact structure: Small size and light weight, supporting multiple installation methods (such as vertical and horizontal installation), suitable for space-constrained scenarios.
Sealing design: Employing a movable metal valve seat or soft sealing material (such as PTFE), leakage is ≤10⁻⁶ × rated flow coefficient, meeting stringent sealing requirements.
Core Advantages and Application Areas
1. Superior Performance
Adjustment Precision: Flow characteristics are equal percentage, with an adjustable ratio up to 100:1 (some models reach 300:1), suitable for precise flow control.
Low Fluid Resistance: Low pressure drop loss in fully open state, improving system efficiency.
Wear and Corrosion Resistance: Constructed of stainless steel, carbon steel, or with special coatings, suitable for high temperature, high pressure, and highly corrosive media.
Easy Operation: Supports remote automated control; rapid opening and closing (90° rotation completes the switch).
2. Application Scenarios
Chemical/Petroleum: Handling corrosive media, high-viscosity fluids, and materials containing particulate matter (e.g., lime slurry).
Pharmaceutical/Food: Meets hygiene standards for precise dosage control.
Water Treatment: Regulates flow and pressure to control water quality.
Gas/Compressed Air: Controls gas emissions and pressure to prevent pipeline fluctuations.
HVAC: Regulates system flow and temperature to improve energy efficiency.
Power/Lighting: Ensure stable pipe connections and avoid arcing interference.
