J3C Modulating 24-240V AC/DC Electric Actuator 20Nm F05 9 mm

This modulating electrical actuator allows you to control quarter turn (ball or butterfly) valves. It has an operating torque of 20 Nm (higher break torque so please see the manual) and can open/close the valve in 10 seconds with a duty cycle of 75%. It requires a supply voltage of 24-240 V AC/DC and it has a visual positioning indicator on top of the unit to clearly see valve position. As a modulating actuator, it is equipped with a digital positioning system (DPS) meaning it can position the valve anywhere between 0-90 degrees. It requires a control signal of 4-20 mA/0-10 V for positioning. As standard, it does have a manual operation cogwheel for manually rotating the actuator’s stem in case of emergency. It is designed to mount to a quarter turn ball or butterfly valve that has an ISO 5211 F03, F04 or F05 flange with a 9 mm star connection for square drive shafts. It has a durable polyamide (PA) housing making an IP67 enclosure capable of operating in an environment of -20 to 70 °C. Before connecting the actuator, please read the manual carefully.

Pros:

• It is a modulating actuator with a digital positioning system (DPS) to position the valve anywhere between 0-90 degrees with a control signal of 4-20 mA
• It has a robust IP67 housing
• As standard, it does have a manual operation cogwheel for manually turning the valve if needed
• It has a clear visual position indicator to see the valve’s state
• It is designed to mount to a quarter turn ball or butterfly valve that has an ISO 5211 F03, F04 or F05 flanges

Cons:

• The actuator is not equipped with a battery safety return (BSR) but can be operated manually if power fails
• In comparison to a pneumatic actuator of the same size, the operating speed is slower

J3C series

The J3C high voltage electric valve actuators from manufacturer J+J offers an impressive list of standard features that include protection against damage from over-torque or condensation. Actuators are also available with different options like fail-safe BSR (Battery Safety Return) or modulating called DPS (Digital Positioning System). The series has an operating torque range between 20-300 Nm. The J3C fail-safe or modulating electric actuator is the same as the standard on-off J3C actuator but a BSR and/or a DPS kit is added inside the actuator. The J3C BSR fail-safe actuator can be set to fail open or fail closed. The J3C DPS modulating actuator can be controlled with 4-20 mA or 0-10 V (0-10 V on request).
