TAILONZ PNEUMATIC 4V210-08 DC12V Valve
Product Name: 2-Position 5-Way Solenoid Valve (Outlet wire). Voltage: DC12V. Working pressure: 25~116 ℉. Working Temperature: 32-140 ℉. Working Principle: When the coil is powered off, the valve stays open; when powered on, it closes. This configuration suits compact circuits requiring fast actuation with a normally open state when de-energized.
TAILONZ PNEUMATIC 4V210-08 DC24V Valve
Product Name: 2-Position 5-Way Solenoid Valve (Junction Box). Voltage: DC24V. Working pressure: 25~116 ℉. Working Temperature: 32-140 ℉. Working Principle: When the coil is powered off, the valve stays open; when powered on, it closes. This variant accommodates higher control voltages while preserving the same 4/2 actuation logic.
TAILONZ PNEUMATIC 4V210-08 AC110V Valve
Product Name: 2-Position 5-Way Solenoid Valve (Junction Box). Voltage: AC110V. Working pressure: 25~116 ℉. Working Temperature: 32-140 ℉. Working Principle: When the coil is powered off, the valve stays open; when powered on, it closes. This variant is suited for AC-powered control circuits prevalent in industrial settings.
Baomain 4 Station Solenoid Valve Manifold
Product Name: 4-Station Integrated Manifold. 24V DC. 4 Station, 2-Position, 5-Way Pneumatic Design. Includes manifold base and mufflers. Quick-connect 8mm base ports and 6mm exhaust ports for efficient installation. Designed to simplify multi-valve control in compact automation layouts.
Beduan 2 Way Normally Closed DC 12V Valve
Product Name: 2-Way Normally Closed DC 12V. Port Size: 1/4″ NPT. Material: Anodized aluminum. Temperature range: 23-176 ℉. Pressure range: up to 115 PSI. Suitable for simple on/off control in pneumatic lines with direct actuation needs.
Buyers Products BAV050SA 4-Way Valve
Product Name: 4-Way 2-Position Solenoid Valve. Five 1/4 inch NPT ports. Designed for remote operation with an electronic switch. Easily converted to 3-way operation. Commonly used in tailgate and pneumatic system applications where remote actuation is beneficial.
Hanshang Hydraulic NG6 D03 4-Way Valve
Product Name: 4-Way, 6 Port (NG6), 12V DC. 60 L/min maximum flow. Designed for use with sub-plates or NG6 or D03 manifolds. Suited for mobile and stationary automation equipment requiring robust 4-way control.
Buying Guide: Key Purchase Considerations
- Valve type and actuation: 4/2 valves come in direct-acting and pilot-operated configurations. Pilot-operated valves are common for higher flow and pressure while direct-acting types can be simpler but may have lower flow.
- Voltage and compatibility: Ensure your control system voltage matches the coil (DC12V, DC24V, AC110V). Some valves include junction boxes for easier wiring.
- Port size and thread: Common sizes include 1/4″ NPT and 1/2″ NPT. Verify inlet/outlet and exhaust port dimensions for your hoses or fittings.
- Material and environmental ratings: Aluminum bodies suit general purpose use; consider corrosion resistance for humid or chemical environments. Temperature and pressure ranges matter for reliability.
- Number of stations and mounting: A manifold consolidates several valves for compact installations. Evaluate space, maintenance, and future expansion needs.
- Leakage and durability: Look for low internal leakage and long service life for critical applications. Check rated Cv flow to gauge performance with your load.
- Electrical considerations: Some models are NC (Normally Closed) or NO (Normally Open). Understand how energizing or de-energizing affects valve position in your circuit.
- Warranty and replacement parts: Access to seals, diaphragms, and coil replacements can affect total cost of ownership.
- Installation and maintenance: Quick-connect fittings and mufflers reduce assembly time and noise. Consider whether you need a pre-wired valve or remote mounting options.
This collection covers a range of voltages and configurations to suit common 4/2 valve applications, from compact 1/4″ NPT lines to multi-valve manifolds. When selecting, map your system’s control logic, pressure range, and space constraints to the valve’s specifications to ensure reliable operation.
