VBA20A-F03

SMC's cylinder VBA20A-F03 Key ParametersType: Pneumatically-driven pneumatic booster valve (no external power supply required, pressure boosting achieved via input air pressure);Port Specification: "F03" corresponds to inlet/outlet thread G 3/8 (compatible with G3/8  pneumatic pipe fittings);Boost Ratio: 2:1 (when input pressure is 0.7MPa, maximum output pressure can reach 1.4MPa);Drive Pressure Range: 0.2-0.7MPa (stable input air pressure is required to avoid pressure fluctuations affecting boosting effect);Maximum Outlet Pressure: 1.4MPa (downstream equipment must match this pressure resistance level);Flow Coefficient: Cv≈0.5 (suitable for small flow scenarios, meeting the requirements of medium and low load pneumatic components);Operating Temperature: 0-60℃ (avoid freezing or high temperatures that may cause seal aging);Mounting Method: Panel mounting (compatible with equipment control cabinet or bracket integration);Core Features: Built-in check valve (prevents pressure backflow), with manual pressure relief function (facilitates maintenance).ApplicationsSuitable for scenarios with local low-pressure air supply or where the force of small-load pneumatic components needs to be increased, such as:Enhancing clamping force of small pneumatic fixtures and grippers (ensuring stable clamping of precision workpieces);Driving small cylinders, solenoid valves, etc., under low-pressure air supply in workshops (main pipeline pressure < 0.5MPa);Short-stroke high-pressure operations (such as micro-stamping and precision pressing) without the need for additional high-pressure air supply;Commonly used in electronic component assembly machines, small machine tools, and auxiliary pneumatic systems for medical equipment.
