Pneumatic Air Valve 3 Ways 2 Position 1/4"BSPT Hand Push Pull Control 3R210-08. R : Represents amanual operation structure ("R" is usually an identifier for "Manual"). 2.210 : Specification and Operation Mode. Function and Application Scenarios. Direct Supply BRAND NEW PARTS I. Breakdown and Meaning of the Model 1. 3R : Series and Structural Type 3 : Indicates there are 3 ports , namely the P port (air supply inlet), A port (working port), and R port (exhaust port). It is classified as a 3-way valve, suitable for controlling single-acting actuators (such as single-acting cylinders). R : Represents a manual operation structure ("R" is usually an identifier for "Manual"). The valve core is driven by manual means such as knobs, buttons, or levers, requiring no electricity. It is suitable for non-automated or emergency operation scenarios. 2. 210 : Specification and Operation Mode 2 : Indicates the valve body specification , corresponding to a nominal diameter of 1/8 inch (approximately 3.175mm), 适配小流量气动回路（如小型气缸、气动吸盘等）. 10 : Here, it indicates the reset mode , usually "spring return" — that is, the valve core switches position during manual operation, and automatically resets to its initial state (normally closed or normally open) by spring force when released. 3. -08 : Additional Parameter (Usually Installation Method or Interface Type) The suffix "08" in some brand models represents the installation method or interface type . Based on common specifications, it may indicate "pipe mounting" here (directly connected to pipelines via threads), compatible with pipeline systems with 1/8-inch threaded interfaces. II. Function and Application Scenarios Core Function : Controls the on-off of the air path through manual operation — during operation (e.g., pressing a button or turning a knob), the P port is connected to the A port (compressed air enters the actuator); when released, the spring resets, and the A port is connected to the R port (the actuator exhausts and resets). Typical Applications : Manual control of pneumatic systems (e.g., manually starting/stopping small cylinders); Emergency operation of automated equipment (e.g., manually resetting cylinders during power outages); Simple pneumatic circuits in laboratories or small equipment that do not require electric control. III. Product Features Simple structure, no need for a power supply, high reliability, and easy maintenance; The spring return design ensures automatic recovery to the initial state after operation, suitable for temporary control scenarios; The 1/8-inch diameter adapts to small flow requirements, with flexible installation (mostly pipe-mounted, directly connected to hoses or hard pipes).
