MN Machinery Auto Trading supplies 4R and 3R Series Mechanical Hand-Draw, Hand-Operated Solenoid Valves, designed for air control applications. These valves operate using a direct-acting type mechanism and support 3/2 port (3H) and 5/2 port (4H) configurations, making them suitable for various pneumatic control systems.
The valves are manufactured with an aluminum alloy body and NBR seals, providing stable operation under working pressures from 0 to 0.8 MPa and temperatures ranging from 0°C to 60°C. The 3R and 4R series valves are available in different models with varying effective sectional areas and port sizes, offering flexibility for different air flow requirements. Lubrication is not required, simplifying maintenance and operation.
