Motorized valve actuator CMQ

manualquarter-turnpart-turn

Description
CMQ part-turn output compact modulating actuators provide an all-electric solution for control valve and pump applications. They deliver precise, repeatable position control and continuous modulation with accuracy up to 0.1%. Units are certified explosionproof to international standards and can be supplied with optional integral local controls and a Reserve Power Pack for fail-to-position capability.

Features

• High-torque quarter-turn option using CMR-250 with GBX spur gearbox
• Precise, repeatable position control using 4–20 mA command with up to 0.1% accuracy
• Explosionproof certification to international standards
• Adjustable speed control
• Manual override standard
• Electronic torque limiting
• Two standard adjustable position switches
• Suitable for mounting in any orientation
