A control valve block is a compact, integrated manifold system within a gripper head (vacuum pad/mechanical claw) that centralizes the control of pneumatic or hydraulic circuits. It manages the actuation, release, and pressure regulation for gripping operations, ensuring precise and reliable manipulation of objects. The block is typically machined from aluminum alloy, stainless steel, or brass, with anodized aluminum (6061-T6) as a common body material. It features multiple ports (4–12) for tube connections, with valve sizes ranging from 6 to 25 mm (ISO 4400). Operating pressure is specified as 1.0–1.6 MPa, and flow rates range from 10 to 60 L/min. Response time for full valve opening or closing is 10–50 ms, and leakage rate at rated pressure is ≤0.1 cm³/min (ISO 5208). The block operates in non-condensing environments from -20°C to 80°C and offers ingress protection of IP54–IP65 (IEC 60529). Seals are made of NBR or FKM (ASTM D2000), depending on fluid compatibility and temperature requirements. Weight ranges from 0.8 to 3.5 kg, and dimensions vary from 80×60×40 mm to 200×120×80 mm, depending on port count and configuration. The working principle involves receiving compressed air or hydraulic fluid from a supply line and distributing it through internal passages to individual solenoid or manual valves. These valves open or close to direct flow to the gripper's actuators, controlling grip, release, and force. The block may include regulators, flow controls, and pressure sensors for fine-tuning. For selection, verify model-specific parameters such as exact pressure rating, flow capacity, port configuration, and material compatibility with the intended fluid and environment. Always confirm standards compliance with the legal manufacturer or supplier, as listed standards are reference points, not guarantees of certification.
