UNOX 1-1/2″ Motorized Ball Valve 24V DC
The UNOX 1-1/2″ model is designed for heavy-duty water, air, or gas lines with a 63 Bar pressure rating. It uses a stainless AISI304 3-piece body and a sealed IP67 actuator for outdoor and harsh environments. Best for industrial automation where maintenance access and durability matter. Choose this if you need robust high-pressure performance and long service life in demanding systems.
Best for: industrial automation, outdoor installations, and high-pressure applications. Limitation: larger size may require compatible piping and fittings.
U.S. Solid 2 in Motorized Ball Valve
This 2″ valve features a full-port 304 stainless steel bore for maximum flow and a plug-and-play US power cord for quick setup. With a 145 PSI rating and a fail-safe auto return, this model is ideal for leak and overflow protection in larger piping networks. Best for: facilities needing fast, simple installation and strong flow capability. Caution: ensure your control system supports its voltage and wiring arrangement.
UNOX Ø110 (4″) Motorized Ball Valve
This U-PVC 4″ valve is designed for water, air, and compatible liquids with corrosion resistance and excellent longevity. It’s lightweight for easy handling and supports HVAC and irrigation roles. Best for: HVAC systems and irrigation lines requiring corrosion resistance and automation. Limitation: higher initial footprint and potential material compatibility checks for certain chemicals.
UNOX 1″ Motorized Ball Valve 24V DC
The 1″ UNOX valve uses AISI304 stainless steel and a 2-piece threaded body for versatile, durable installations. It supports 63 Bar and offers 24V DC control with IP67-rated actuator. Best for: mid-range industrial applications and processes requiring robust, compact automation. Choice tip: consider control voltage availability in your plant when selecting 24V vs other voltages.
Buying Guide
What should you consider before buying?
- Pressure rating and port size: Match the valve to your system’s pressure (e.g., 63 Bar) and pipe diameter to avoid flow restrictions.
- Material compatibility: Stainless steel (AISI304) resists corrosion; U-PVC is lighter and suitable for HVAC and certain liquids.
- Actuator sealing and protection: IP67-rated actuators offer better dust and water protection in outdoor or damp environments.
- Voltage and control option: Ensure the valve’s voltage (24V DC, 110V, 220V) aligns with your control system and power availability.
- Full port vs reduced port: Full-port designs minimize pressure drop, important in large-diameter connections.
- Maintenance and serviceability: Three-piece bodies generally provide easier maintenance access than compact designs.
Installation considerations
- Threading vs flanges: Confirm the correct NPT threading size for direct bolt-in compatibility.
- Power supply: For quick installations, models with pre-wired plugs reduce wiring effort and errors.
- Automation integration: If using PLC or building automation, verify compatibility with 4-20mA or equivalent control schemes.
Scenario-based recommendations
- Best for high-pressure industrial lines: UNOX 1-1/2″ (63 Bar) and UNOX 1″ (63 Bar).
- Best for large-diameter piping with easy setup: U.S. Solid 2″ motorized valve with plug-and-play wiring.
- Best for HVAC or irrigation: UNOX Ø110 (4″) U-PVC valve for corrosion resistance and weight savings.
- Best for potable water and home automation: U.S. Solid 1/2″ NSF Certified valve for safe drinking water.
FAQ
- What is an electric actuated ball valve?
It is a ball valve operated by an electric motor that opens or closes the flow based on electrical control signals.
- Do these valves require special wiring?
Some models come pre-wired with a US plug; others require standard electrical connections. Check voltage requirements.
- What does IP67 mean for the actuator?
IP67 indicates complete dust protection and water immersion up to 1 meter for 30 minutes.
- Are these suitable for drinking water?
NSF-certified models use 304 stainless steel and safe materials suitable for potable water lines.
- What maintenance is needed?
Periodic inspection of seals and actuators; three-piece designs may offer easier service access.
- Which valve should I choose for a PLC system?
Prefer models offering 4-20mA or compatible control schemes and compatible voltage options.
