Overview

Mercon quarter turn pneumatic actuator
Operating air supply pressure range
2 bar(29 psig) to 8 bar(116 psig) double acting
3 bar(44 psig) to 8 bar(116 psig) spring return

Temperature range

Bottom drilling complies with ISO 5211/DIN 3337 to match valve. Interface for solenoid valve, shaft top end and top drilling for assembling accessories are in accordance with VDI/VDE-3845, NAMUR standard.

PINION the hardened alloy steel pinion is precision ground and nickel plated (over 15um) in order to reduce friction, provide maximum wear resistance. Full conformance with the latest standards of ISO5211 & DIN3337.

ACTUATOR body the aluminium extrusion is hard anodized(over 30um) to protect against wear and corrosion while reducing piston friction to the absolute minimum. A heavy duty PTFE coating is applied to the external surface to resist corrosion & dust accumulation.

PISTONS the precisely-balanced and hard anodized treatment (over 30um)die cast aluminium pistons are fitted with high quality rings and guides. The twin rack and piston design creates a constant torque output on all actuators.

HIGH performance springs the high tensile steel springs are epoxy coated for corrosion resistance and longer service. The pre-loaded springs can be safely & rapidly disassembled.

Standard: NBR O-rings -20°C(-4°F) to +80°C(+176°F)
Optional high temperature: Viton O-rings: -15°C(+5°F) to +150°C(+300°F)
