Airtac 4V310-08 Industrial Air Solenoid Valve Good Sealing Stability Low Starting Pressure Suitable For Automation Assembly Line Pneumatic Control System

The 4V series encompasses a comprehensive selection of pilot-operated 5/2-way pneumatic solenoid valves. This range includes individual replacement coils and pre-assembled multi-station manifold kits, all engineered to provide dependable directional control of compressed air in industrial automation applications. The valves are available with port sizes ranging from 1/8″ to 1/2″, offering flow capacities (Cv) that increase from roughly 0.56 to 2.80, catering to various actuator dimensions and speed demands.

Customers can choose from fully assembled single or double solenoid valve units, valve bodies intended for manifold integration or replacement purposes, and individual replacement coils in AC220V or DC24V for convenient field maintenance. The multi-station manifold kits come pre-configured in arrangements of 2 to 10 stations for the 4V210-08 and 4V110-06 models. Additionally, specialized kits are available for the 4V310-08 and 4V310-10 series. By centralizing the P (inlet) and R/S (exhaust) ports within the manifold design, external fittings and potential leak points are reduced by more than 70% compared to configurations with individual valve piping. Independent wiring for each station enables the combination of AC and DC voltages on a single manifold block, adding versatility for systems that integrate PLC controls with manual safety switches.

The valve bodies are made from a durable aluminum alloy and feature a sliding column structure that ensures a quick response and minimal friction during operation. These valves operate without the need for oil lubrication; however, if lubricated air is used, it should be supplied continuously, preferably with ISO VG32 or an equivalent lubricant. A manual override mechanism is included as a standard feature, allowing installation and debugging to be performed without electrical power. The coils have an IP65 rating and consume approximately 3 VA (AC) or 3 W (DC), depending on the specific variant.

The standard operating pressure range for these valves spans from 0.15 to 0.8 MPa (21 to 114 psi), with a proof pressure rating between 1.2 and 1.5 MPa depending on the source. This robust design ensures reliable performance and safety in a variety of industrial pneumatic systems.

The port sizes range from 1/8″ to 1/2″, accommodating various models including 4V110-M5, 4V110-06, 4V210-06, 4V210-08, 4V310-08, 4V310-10, and 4V410-15. This wide range ensures compatibility with multiple pneumatic applications and systems.

Featuring a 5/2-way pilot-operated directional control design, these valves offer reliable switching functions ideal for double-acting cylinders and pneumatic actuators. This configuration guarantees efficient and precise control in pneumatic circuits.

Options are available with either single or double solenoids. The double solenoid variants include a memory function, which holds the valve position, enhancing control stability and response consistency in operation.

For applications requiring manifold integration or replacement where coils and wiring are already established, a valve body-only option is offered. This flexibility allows for easier maintenance and system upgrades without extensive rewiring or component replacement.

Individual replacement coils are available in AC220V and DC24V versions, supporting field servicing without the need to replace the entire valve assembly. This feature reduces downtime and maintenance costs significantly.

The product line includes multi-station manifold kits that come pre-assembled in configurations ranging from 2 to 10 stations for models like 4V210-08 and 4V110-06. Additionally, kits are available for 4V310-08 and 4V310-10, which help minimize installation space requirements and shorten assembly time.

Centralized air logistics is achieved through unified large-diameter P and R/S ports, which reduce the number of external fittings and potential leak points by over 70%. This design enhances system reliability and simplifies pneumatic connections.

Voltage blending capability on a single manifold is enabled by independent station wiring, allowing both AC and DC voltages to be used simultaneously on a compact valve block. This makes it easier to customize and expand pneumatic control systems.

Modular expansion is possible through the use of blank plates that seal unused stations. These can be upgraded at a later time without the need to re-plumb the main air supply, providing future-proof flexibility and simplified system modifications.

The valve body is constructed from aluminum alloy, ensuring a lightweight yet durable unit suitable for industrial environments. This material choice balances strength with ease of handling and installation.

The sliding column structure offers excellent sealing performance along with a sensitive response and low friction. These characteristics contribute to efficient operation and longer valve life.

Lube-free operation eliminates the need for oil maintenance and prevents contamination caused by oil mist, making these valves an excellent choice for sensitive applications such as food processing and electronics assembly.

A manual override is included as a standard feature, which aids in installation, troubleshooting, and emergency operation by allowing manual control of the valve when necessary.

Coils are protected to IP65 standards, making them dust-tight and resistant to water jets. This ensures dependable performance even in harsh or demanding environmental conditions.

The valves operate within a pressure range of 0.15 to 0.8 MPa, making them suitable for a broad spectrum of industrial pneumatic systems. Additionally, they provide a proof pressure between 1.2 and 1.5 MPa for enhanced safety during pressure surges.
