Electric V-Port Ball Valve | Flanged Modulating Control Valve | DELCO

• Precise Throttling & Equal Percentage Characteristic:

The precision-machined V-notch ball delivers an inherent equal-percentage flow curve across the entire 90° stroke. It provides wide rangeability and micro-flow control, effectively preventing flow surges and pipeline cavitation during throttling.

• Self-Cleaning & Anti-Clogging Shearing Action:

As the V-port ball rotates against the seat, it creates a robust shearing force that slices through fibrous materials, paper pulp, suspended solids, and viscous slurries, preventing seat jamming and ensuring tight shutoff.

• Heavy-Duty Pressure Body & Hardened Trim:

Rugged valve body forged/cast in ASTM A216 WCB or CF8M stainless steel to withstand high pipeline pressures. Available with hard-faced metal seats (Stellite / Tungsten Carbide) or reinforced PTFE seats to resist erosive wear in abrasive environments.

• Corrosion-Resistant Actuator Housing (IP67):

The electric actuator casing is cast from high-strength aluminum alloy, treated with hard anodization and an electrostatically applied polyester powder coating. Rated IP67 weatherproof to resist severe chemical vapor, salt spray, and outdoor weathering.

• Intelligent Modulating & Anti-Reverse Self-Locking:

Features a built-in intelligent servo controller supporting 4-20mA DC or 0-10V DC input/feedback signals. High-precision worm gear transmission guarantees low operating noise (<50 dB) and automatic self-locking to prevent reverse flow displacement under pressure surges.

• Industrial-Grade Motor with Overheat Protection:

Equipped with a high-torque, low-inertia squirrel-cage motor with Class F insulation. Integrated thermal overload protection prevents motor burnout during high-frequency modulating cycles.
