QUALITY FEATURES PNEUMATIC ACTUATOR SPRING UNITS Single-acting actuators are equipped with two spring cups, so that the actuator can clearly be recognised as single-acting. Six different spring untis are available, depending on the actuator size. The springs are prestressed, allowing the spring units to be replaced safely and easily. PISTON GUIDE The piston bearing surface of the cylinder tube is precisely machined and anodised. The result: good wear resistance and consistently high efﬁciency in continuous operation. Sliding pads and piston rings made of UHMWPE ensure low-friction piston guidance and prevent metallic contact between piston and cylinder. SH A F T BE A RING The multiple shaft bearing reduces friction losses to a minimum and guarantees high efﬁciency. SCOTCH YOKE CONCEPT The structurally-dependent lever action is optimally matched to the torque curve. NAMUR CONNECTION BLOCK The NAMUR connection block can be rotated by 180° in order to change the function of the solenoid valve from “Normally closed“ to “Normally open“. COR ROSION - R ESISTA NT SCR E W CONNEC TIONS All screw connections are stainless steel, thus guaranteeing corrosion protection and safe connection even with aggressive recirculating air. PINNED DOUBLE YOKE The pinned ﬁtting of the double yoke guarantees backlash-free force transmission and protects the shaft from blow-out. A D JUSTA BLE LIMIT STOPS The piston limit stop can be adjusted very precisely within a r
