Non-Spring Return Direct Coupled Globe Valve Actuators For Higher Torque Applications
ML6421, ML7421

Direct Coupled Globe Valve Actuators mount directly on V5011 and V5013 steam and water globe valves without a linkage. These Non-Spring Return Actuators will operate 1/2 to 6 in. valves.

• Easy and quick installation on valves with 1 3/8” bonnet and 3/4” stroke, or with 1 7/8” bonnet and 1 1/2” stroke.
• High force for VGF Pressure-balanced valves.
• No separate linkage required.
• Conduit connector standard.
• No adjustments required on linkage.
• Accurate valve positioning.
• Low power consumption.
• High close-off ratings.
• Force limiting end switches.
• Manual operator.
• Synchronous motor.
• Maintenance free.
