VBA43A-F04

SMC's cylinder VBA43A-F04 Key ParametersType: Pneumatically-driven pneumatic booster valve (no external energy source required, pressure boosting achieved via input air pressure);Port Specification: "F04" corresponds to inlet/outlet thread G 1/2 (compatible with standard 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 ensure boosting effect);Maximum Outlet Pressure: 1.4MPa (must match the pressure resistance level of downstream equipment);Flow Coefficient: Cv≈0.8 (reflects gas flow capacity, suitable for medium and low flow scenarios);Operating Temperature: 0-60℃ (avoid low-temperature freezing or high temperatures affecting sealing performance);Mounting Method: Panel mounting or bracket fixing (compatible with automated equipment integration);Core Features: Built-in check valve (prevents pressure backflow), with pressure relief function (facilitates maintenance and pressure release).ApplicationsSuitable for scenarios where local air pressure is insufficient or the force of pneumatic actuators needs to be increased, such as:Enhanced clamping force of pneumatic grippers and fixtures (ensuring stable workpiece clamping);Driving actuators such as cylinders and valves in low-pressure air supply environments (e.g., workshop main pipeline pressure less than 0.5MPa);Short-term high-pressure operations (e.g., stamping and pressing processes) without the need for additional high-pressure air supply configuration;Commonly used in automated scenarios such as machine tools, automotive parts assembly lines, and electronic equipment assembly machines.
