The 4R Series is a two-position five-way drawing hand valve designed for pneumatic control systems, compatible with 40 micron filtered air as the working medium. Models in this series include 4R210-08, 4R310-08, and 4R310-10, each engineered with specific port configurations: G1/4 for air inlet and outlet with G1/8 exhaust, uniform G1/4 across all ports, or G3/8 for inlet and outlet with G1/4 exhaust. Working pressure ranges from 0 to 0.8 MPa (0 to 114 psi), and the operational temperature spans 0 to 60 degrees Celsius, making it suitable for industrial environments with controlled air supply.
Constructed for durability, the valve features effective sectional areas of 16 mm², 25 mm², or 30 mm², with corresponding flow coefficients (Cv) of 0.89, 1.4, and 1.68. These metrics ensure consistent performance in applications requiring precise air flow regulation, such as automation machinery and assembly lines. The valve’s two-position design allows for reliable switching between circuits, a standard requirement in pneumatic systems where directional control is critical.
This series is used in manufacturing plants, packaging equipment, and automated production lines where pneumatic actuation is essential. Buyers typically source these valves for OEM integration or replacement in existing systems. The supplier, based in Ningbo’s Fenghua district, provides the valve with standard pneumatic industry specifications, and buyers are advised to confirm compatibility with their system’s pressure and port requirements before ordering.

Before ordering, verify the valve’s compatibility with your system’s pressure and port requirements. Confirm that your air supply meets the 40 micron filtration standard, as contamination can damage the valve and void warranties. Additionally, check if the valve’s working temperature range aligns with your operational environment to avoid material or performance issues.
Clarify logistics details such as lead time, Incoterms (e.g., FOB Ningbo), and packaging standards to ensure the valve arrives in usable condition. The supplier’s harbor trust tier suggests reliability, but buyers should still confirm shipping terms, insurance coverage, and any export restrictions. Payment terms, such as TT or LC, should also be discussed upfront to avoid delays.
For quality assurance, request the supplier’s inspection reports or third-party certifications for the 4R Series. Conduct a visual and functional check upon receipt to ensure the valve matches the specifications, including port sizes and pressure ratings. If applicable, perform a pressure test to confirm the valve operates within the stated 0 to 0.8 MPa range. Always retain documentation for warranty claims or future reference.
