Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›This is a two-position five-way pneumatic control valve with models 4A210-08, 4A220-08, 4A310-10, and 4A320-10, designed for filtered air applications requiring precise directional control. It operates at a working pressure of 0.15 - 0.8 MPa (21 - 114 psi) with a proof pressure of 1.2 MPa (174 psi), and functions within a temperature range of 5 - 50 degrees Celsius. The valve uses an inside pilot operation type and is constructed from aluminium alloy, offering durability and corrosion resistance for industrial environments.
Port configurations vary by model: air inlet and outlet sizes are G1/4 with G1/8 exhaust for smaller units, while larger variants feature G3/8 inlet and outlet with G1/4 exhaust. The valve achieves a highest action frequency of 5 cycles per second, with a shortest excitation time of 0.05 seconds, making it suitable for high-speed pneumatic systems. Effective sectional areas are 16 mm² (Cv=0.89) and 30 mm² (Cv=1.68), ensuring efficient flow control for compressed air circuits.
These valves are used in automation systems, machinery, and process control applications where rapid, reliable switching of air flow is critical. Typical buyers include manufacturers of packaging equipment, assembly lines, and robotic systems. The valves are supplied in weights of 185 g, 285 g, 275 g, or 365 g, depending on the model, and are compatible with standard pneumatic tubing and fittings. Importers should confirm compatibility with their existing systems and verify pressure ratings against application requirements.

Before ordering, verify that the valve’s working pressure range (0.15 - 0.8 MPa) and proof pressure (1.2 MPa) match your system’s requirements. Check compatibility with your pneumatic tubing and fittings, particularly the port sizes (G1/4 or G3/8 for inlet/outlet, G1/8 or G1/4 for exhaust). Confirm the model’s weight and dimensions to ensure it fits within your equipment’s spatial constraints.
Discuss logistics details such as lead time, shipping method, and Incoterms with the supplier. Ningbo’s port infrastructure supports efficient export, but buyers should clarify whether FOB Ningbo or another Incoterm applies. Payment terms, such as TT (Telegraphic Transfer) or LC (Letter of Credit), should also be agreed upon in advance to avoid delays.
Request a quality inspection report or third-party test certificate to confirm the valve’s performance under stated conditions. Key tests include pressure resistance, leak testing at maximum working pressure, and action frequency validation. For critical applications, arrange for on-site inspection or third-party certification to ensure compliance with industry standards like ISO 6431 for pneumatic directional control valves.
