OM SERIES – 90° TURN ELECTRIC ACTUATOR IP67

The OM series is a robust range of 1/4 turn electric actuators suitable for the on/off activation of Ball or Butterfly valves.

A powerful motor with inbuilt thermal protection drives a pre-lubricated heavy duty steel gear train running in bronze bushes. They are encased in a powder coated die cast protective housing that has an IP67 rating (dust tight and submersible for limited periods).

All models have a visual position indicator and a manual override.

The ISO 5211 mounting and female square drive allows direct coupling to valves with a similar configuration.

Standard models drive through 900 and can be fitted with voltage free contacts for end of stroke feedback.

Positioner models with 4-20mA or 2-10v modulating control are also available in all sizes.

STANDARD FEATURES:

• IP67 weatherproof rating and Humidity up to 95%.
• Ambient temp. -5°c ... +600G.
• Duty cycle is 30% to 75% depending on ambient temperature, voltage and actuator model, and relates to the 135°G thermal (some modulating versions have a 75% duty cycle).
• Always allow a 35% safety margin when sizing torque requirements.

OPTIONAL FEATURES:

• Torque limit switch (overload protection).
• Anti-condensation heater - 15 watt.
• Two SPOT voltage free micro switches and cams (end of stroke feedback).
• Potentiometer and position transmitter (4-20mA feedback).
• Modulating control (4-20mA or 2-1Ov input and feedback).
