Electric valve actuator SM

90°rotarypart-turn

Overview
SM-1700 and SM-5000 electric modulating actuators provide precise positioning for dampers, vanes and valves. Internally geared, they deliver up to 16,950 Nm (12,500 lbf.ft) of torque with continuous modulation. Units include automatic torque limiting and a self-locking drive to hold the last position and prevent backdriving.

Features

• SM-1700: 90 to 120 degrees rotation
• SM-5000: 33 to 90 degrees rotation
• Modulating duty: up to 2,000 starts per hour
• Manual override: standard
• Automatic torque limiting: standard
• Self-locking drive to hold last position and prevent backdriving up to thrust rating
• Power options: single-phase, three-phase or Direct Current (DC) — DC available only for SM-1700

Applications

• Dampers
• Vanes
• Valves
• Other process control applications requiring exact positioning control
