J4C Modulating Fail-Safe 24-240V AC/DC Actuator 20Nm F03 9 mm

This modulating electrical actuator with fail safe function 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 9 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. It is also equipped with a battery safety return (BSR) as an electronic safety function. If power is lost, the battery will power the actuator enough to put it back to its normal state (normally open/closed depends on how it is mounted). 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 is equipped with a battery safety return (BSR) to power the actuator to rotate the valve back to its normal state
• 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:

• In comparison to a pneumatic actuator of the same size, the operating speed is slower

J4C series

The J4C 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 J4C fail-safe or modulating electric actuator is the same as the standard on-off J4C actuator but a BSR and/or a DPS kit is added inside the actuator. The J4C BSR fail-safe actuator can be set to fail open or fail closed. The J4C DPS modulating actuator can be controlled with 4-20 mA or 0-10 V (0-10 V on request).
