INTRODUCTION
This premium flow control solution integrates a heavy-duty 3-piece stainless steel ball valve with a high-performance electric actuator. Engineered for reliability and precision, it provides a comprehensive hardware suite for automated systems, offering superior durability, seamless integration, and simplified maintenance in demanding industrial environments.
FEATURES
- Premium Material Construction: Crafted from high-grade 304 stainless steel, the valve body is highly resistant to corrosion, making it suitable for handling weak acids, weak alkalis, chemical solvents, and water.
- Maintenance-Friendly 3-Piece Design: The innovative 3-piece body construction allows for seamless in-line maintenance. Internal components can be cleaned or replaced without disconnecting the pipes, helping reduce downtime and service costs.
- High-Pressure & Full-Bore Efficiency: The full-bore configuration helps minimize pressure drop and maintain efficient flow capacity in high-pressure systems.
- Smart Automation Ready: Integrated limit switches and position feedback support PLC integration, remote control, real-time monitoring, and automated operation.
- High-Torque Reliability: A compact, heavy-duty motor delivers steady 50 Nm torque for reliable full-port operation and drop-tight sealing.
- Enhanced Safety & Self-Locking: The actuator features a self-locking mechanism for stable operation and a manual override port for controlled intervention during power outages or emergencies.
- Rugged Outdoor Durability: A powder-coated polyester aluminum housing provides resistance to corrosion and harsh weather conditions.
- Advanced Circuitry Protection: The internal PCBA is treated with a protective sealant to help prevent damage from moisture, condensation, and short circuits.
APPLICATIONS
WIRING DIAGRAMS
- Multi-Signal Modulating Control: Accepts 4-20 mA, 1-5V, or 0-10V DC input signals to automatically
- Precise 4–20 mA Modulating Control: Receive a standard 4–20 mA control signal and automatically position the valve for smooth, reliable flow regulation.
- Automatic Electronic Positioning: The electronic positioner continuously compares the commanded setting with the actual valve position, then adjusts the actuator as needed to maintain the target opening.
- Real-Time 4–20 mA Position Feedback: Send actual valve-position feedback to a compatible PLC, DCS, or process controller for convenient remote monitoring and control verification.
- Closed-Loop Position Accuracy: A three-wire position feedback potentiometer continuously tracks valve travel, helping deliver stable, repeatable modulation across the full 0–100% stroke.
- 24 VDC Power Supply: Designed for 24 VDC operation, with clearly marked positive (`+`) and negative (`−`) power terminals for straightforward installation.

WARNINGS
- Power Failure Behavior: This valve remains in its current position during a power outage. It does not automatically return to a preset position.
- Voltage Match Required: Supply voltage must match the actuator rating exactly. Incorrect voltage may permanently damage the unit.
- Dedicated Power Circuit: Each actuator requires its own fuse-protected power supply. Do not connect multiple actuators in parallel.
- Disconnect Power Before Service: Always disconnect power before wiring, maintenance, or using the manual override.
- IP65 Weather Resistant: Suitable for outdoor use, but additional protection is recommended for permanent outdoor installations.
- Low Power Consumption: Power is only used during opening and closing. No power is consumed when fully open or fully closed.
- Professional Installation Recommended: Installation should be performed by qualified personnel familiar with electrical control systems.
FAQ
1. Can I manually operate the valve?
A: Yes. The actuator features a manual override. We recommend manually cycling the valve before installation to verify smooth operation and using the adjustment screws during commissioning to fine-tune the open and closed positions.
2. Can this valve be installed outdoors?
A: Yes, depending on the model's IP rating. While our heavy-duty actuators are weather-resistant, we recommend using a protective cover or shelter for permanent outdoor installations to protect the unit from direct UV exposure and ice buildup.
3. Is this valve suitable for high-viscosity fluids or particulates?
A: Yes, subject to torque considerations. Extremely viscous media or large particulates increase resistance, so ensure the operating torque remains within the actuator's rated capacity to prevent stalling.
4. Is it normal for the actuator to feel hot during operation?
A: Yes. The actuator may feel warm during continuous cycling. If the housing becomes too hot to touch, check that the recommended duty cycle and ambient temperature range of -30°C to 60°C are not exceeded.
5. Can I wire multiple actuators in parallel on the same circuit?
A: No. Each motorized actuator should use its own dedicated, fuse-protected power supply to ensure proper signal response and reduce the risk of electrical interference or damage.
