TAILONZ PNEUMATIC 4V210-08 Solenoid Valve
Product Name: 2-Position 5-Way Solenoid Valve (Junction Box). Voltage: AC110V. Working pressure: 25~116 PSI. Operating range: 32-140°F. Mechanism: When the coil is powered off, the valve stays open; when powered on, it closes. Best for automated actuators where a remote electrical signal should switch flow direction quickly. This is a good fit for DIN- or junction-box mounted panels where a single solenoid unit controls multi-port actuators.
Who it’s best for: Facilities upgrading pneumatic circuits that require a robust 5-way configuration with electric actuation. Why selected: Combines a compact junction-box style with a standard AC110V coil, enabling straightforward integration into panel-mounted systems. Limitation: The data does not specify a built-in pilot or integrated silencing, so external dampening may be needed for quiet operation.
TAILONZ PNEUMATIC 4H210-08 Hand Lever Valve
Product Name: 5 Way 2 Position Hand Pull Valve. Size: 1/4″NPT. Working Medium: Air. Working Pressure Range: 25Psi~116Psi. Function: Manual control with a push-pull mechanism to switch flow paths. Best for local control and quick changes on the shop floor or in enclosures where electrical actuation is undesired or unavailable.
Who it’s best for: Technicians needing tactile control without electricity. Why selected: The hand lever offers immediate, visible actuation and is well-suited for maintenance tasks or manually exercised pneumatics. Limitation: Not suitable where automated remote control is required.
TAILONZ PNEUMATIC SCF-1/4 Air Flow Control Valve
Product Name: Air Flow Control Valve with Push-to-Connect Fitting. Material: Plastic and Copper. Size: 1/4″ Tube OD x 1/4″ Tube OD. Function: In-line speed control to modulate pneumatic flow. Best for fine-tuning actuator speed in compact circuits where space is limited.
Who it’s best for: Systems needing adjustable actuation speeds without external metering devices. Why selected: Simple inline design with push-to-connect fittings enables quick installation and straightforward maintenance. Limitation: Material mix (plastic and copper) may influence chemical resistance in harsh environments.
TAILONZ PNEUMATIC Green Mushroom Push Button Valve
Product Name: Button Type Pneumatic Valve. Actuation: Green mushroom push button. Port Size: Inlet (P)=1/4″NPT, Outlet(A)=1/4″NPT, Exhaust(R)=1/4″NPT. Function: 3-way, 2-position mechanical control. Best for compact manual overrides or maintenance panels where tactile engagement is required.
Who it’s best for: Local control stations and setups needing a visible, easy-to-press actuator. Why selected: The mushroom style button is highly intuitive for operators. Limitation: Mechanical actuation might not suit fully automated lines requiring remote control.
TAILONZ PNEUMATIC 1/4 Inch NPT Air Flow Control Valve with Push-to-Connect
Product Name: Air Flow Control Unidirectional Throttle Valve. Material: Aluminum. Size: 1/4″ NPT. Function: In-line throttle valve for unidirectional flow control. Best for systems needing durable, lightweight control valves with reliable metal construction.
Who it’s best for: Projects requiring a rugged throttle valve for steady pneumatic speed control. Why selected: Aluminum construction balances strength and weight, suitable for compact boxes. Limitation: May require additional fittings for non-standard tubing systems.
TAILONZ PNEUMATIC Rotary Lever HV-02 1/4”NPT
Product Name: Rotary Lever Hand Valve HV-02. Size: 1/4”NPT. Flow Path: 3 Position 4 Way. Pressure Range: 25-116 PSI. Working Temperature: 32-140°F. Function: Rotary lever provides multi-position routing for pneumatic lines. Best for applications where quick hand-operated reconfiguration of lines is needed.
Who it’s best for: Operators requiring flexible manual routing in a compact footprint. Why selected: The 3-position/4-way capability supports more complex pneumatic circuits in confined spaces. Limitation: Manual operation may not be suitable for fully automated lines.
Buying Guide: Pneumatic Valve Options For Vav Boxes
What to consider when selecting a pneumatic valve controller for a vav box or similar system:
- Actuation method: Decide between solenoid (electrical), manual (hand lever, mushroom button, rotary lever), or flow-control options based on how you want to control the circuit.
- Port configuration: Confirm 3-way, 4-way, or 5-way arrangements and the number of ports per valve to match your actuator or cylinder setup.
- Port size and thread type: Ensure compatibility with 1/4″ NPT or other standards used in your plumbing; mismatches cause leaks or installation challenges.
- Material and build quality: Aluminum and steel offer durability in harsher environments; plastics suit lighter-duty or cost-sensitive projects.
- Environmental conditions: Temperature and pressure ranges determine which valve is appropriate for your application. Higher temperatures or pressures may require more robust designs.
- Control versatility: For automated panels, prefer solenoids or valves with integrated junction boxes; for maintenance or local control, manual valves can be more practical.
Practical Comparison Questions
- Should I choose a solenoid valve for automation or a manual valve for local control? Choose solenoids for remote or automated actuation; manual valves for direct, hands-on control.
- What’s the impact of 5-way versus 4-way configurations? Five-way valves support more complex actuator routing; four-way valves suit simpler double-acting cylinders.
- Is 1/4″ NPT a standard requirement? Yes, 1/4″ NPT is common in compact pneumatic systems and matches many small actuators and fittings.
- Do I need push-to-connect fittings? Push-to-connect simplifies installation and can speed up assembly, especially in tight spaces.
- What maintenance considerations exist? Manual valves require occasional lubrication and verification of mechanical action; solenoids may need coil protection in dusty environments.
FAQ
- What is a 5-way valve used for? A 5-way valve can route air to multiple ports, enabling more complex actuator control in single units.
- Can these valves operate at room temperature? Most listed models are designed for typical industrial ranges; confirm specific temperature limits in a datasheet.
- Are these valves compatible with 24V systems? Some models are AC voltage; check voltage requirements before integration.
- Do manual valves require power? No, manual valves operate without electrical power, making them useful for maintenance or offline testing.
- What is the advantage of push-to-connect fittings? They simplify installation and reduce leak potential, especially in compact assemblies.
- How do I choose between a lever and a mushroom button? Levers offer larger actuation force and tactile feel; mushroom buttons provide compact, visible operation in space-constrained panels.
