HNJPC SC Air Cylinder 2″ Bore, 3″ Stroke
The HNJPC SC air cylinder is a double-acting, aluminum pneumatic cylinder designed for industrial automation with a 2″ bore and 3″ stroke. Its compact SC50X75 footprint and threaded PT1/4 hole provide straightforward mounting and integration into existing systems. Suitable for applications requiring reliable linear actuation with predictable repeatability and decent force output at moderate air pressures. The operating temperature range covers typical factory conditions, and the 0–145 PSI operating window supports common compressed air supplies.
TAILONZ Pneumatic Foot Pedal Valve Kit (3 Way, 2 Position)
This foot pedal valve provides a three-way, two-position control suitable for initiating and stopping cylinder movement through pedal actuation. It supports a maximum pressure of 145 PSI and comes with 1/4″ NPT ports, with additional fittings available for 6mm lines or 1/4″ tubing. Foot-operated control is useful for hands-free operation in assembly lines and ergonomic workflows where continuous manual control is preferred.
LuTangous 5 Way 3 Position Pneumatic Valve
The LuTangous valve is a 5-port, 3-position center-closed pneumatic valve designed for controlling a single cylinder or multiple lines. The aluminum alloy body offers robust durability, while the inner valve core and spacer contribute to improved sealing performance. The unit is installed via G1/4 ports and provides flexible control for extending, retracting, and holding a cylinder at any position, enabling versatile automation sequences.
JDYYICZ 3 Way 2 Position Mechanical Valve
The JDYYICZ green momentary mushroom push-button valve is a manual 3-way, 2-position control suitable for small-scale pneumatic systems. It is designed to excerpt control signals to pilots or diaphragms in larger valves or primary cylinders. With a metal/plastic construction and a 13 mm threaded interface, it offers straightforward installation in compact control stations where manual overrides are necessary.
TAILONZ 180 Degrees Rotary Pneumatic Cylinder
The TAILONZ rotary air cylinder provides a 180-degree rotation with a compact form factor and a maximum pressure of 145 PSI. While not a linear 3-position cylinder, it complements systems requiring rotary actuation in addition to linear cylinders, enabling multi-axis automation setups where precise rotation is part of the process.
TAILONZ 1/4″ NPT 2 Position 3 Way Solenoid Valve
This solenoid valve uses a 2-position, 3-way configuration to direct air flow with electrical control. It supports two-state actuation with a 25–116 PSI working range, making it suitable for responsive valve control within compact pneumatic systems that require quick changes in routing of air to actuators or pilots.
TAILONZ Rotary Hand Lever Valve 3 Position
This hand lever valve offers a 3-position, four-way operation with a rotary control scheme. The 1/4” NPT ports support standard compressed-air connections, and the valve operates within a 25–116 PSI range. It is suitable for manual control tasks that require rapid directional changes in multiple lines.
TAILONZ 5 Way 3 Position Hand Pull Valve
The 5 Way 3 Position Hand Pull Valve offers manual control with push-pull action to switch among in, exhaust, and hold states across multiple lines. With a 1/4″ NPT port size and a working pressure range of 25–116 PSI, this valve is well-suited for compact automation stations requiring straightforward manual override and flexible routing of air flow.
Buying Guide: Key Purchase Considerations
- Control type and position count: Determine whether you need 2-position or 3-position actuation, and whether a foot pedal, hand lever, switch, or solenoid control best fits your workflow.
- Port size and thread standard: Common options include 1/4″ NPT and G1/4 (DN5). Verify compatibility with your existing fittings and tubing to minimize adapters.
- Actuator type: Linear cylinders versus rotary cylinders serve different tasks. Consider whether motion needs to be linear or rotational, and whether a combination is required for your system.
- Maximum pressure and operating temperature: Ensure the component’s pressure rating and temperature range align with your plant’s air supply, ambient conditions, and duty cycle.
- Material and durability: Aluminum bodies offer light weight and corrosion resistance; steel or reinforced components may be needed for rugged environments.
- Mounting and installation: Check for compatibility with standard mounting brackets and whether the unit supports quick-change connectors, easier maintenance, or modular expansion.
- Sealing and leakage: Valve cores and spacers should provide strong seals to prevent air leakage and ensure consistent actuation.
- Maintenance and replacements: Consider availability of replacement seals, or modular components that simplify field service and reduce downtime.
- Integration with control systems: If using solenoids or PLC control, verify electrical requirements (DC voltage, coil resistance) and compatibility with existing control hardware.
These considerations help balance performance, ease of use, and total cost of ownership across a pneumatic automation setup. When selecting three-position components, prioritize reliable actuation, robust seals, and compatibility with your air supply and control architecture to achieve consistent, maintenance-friendly results.
