Solenoid Coils 7019 & 7144 Series

Product Overview

The Automatic Valve Solenoid Coils are replacement and field-upgrade electrical actuation coils designed for use with the Automatic Valve 7019 and 7144 Series directional control valves. Solenoid coils are the electromechanical interface element that converts an electrical control signal into the magnetic force required to shift the valve pilot mechanism, initiating the pneumatic actuation cycle. Specifying the correct coil voltage, power consumption, and connection type is essential to ensure proper valve operation across the full electrical control system design.

The Series includes 28 coil variants, providing coverage across the full range of DC and AC supply voltages used in North American and international industrial installations, including 12 VDC, 24 VDC, 48 VDC, 120 VAC, and 240 VAC at 50/60 Hz. Multiple coil classes address different operating environments, from standard general-purpose duty to high-temperature and classified (hazardous area) applications. The ATEX-compliant variants within the 7019 Series enable direct installation of Automatic Valve pilot valves in Zone 1 and Zone 2 classified areas without additional explosion-proof housings.

The 7019 coil body shown on the product series page carries ratings of 24 VDC at 4.8W and 48V at 50/60 Hz at 8.5/6.9 VA, rated to 10 bar (150 psig), and is CE marked, confirming compliance with EU directives including the ATEX directive where applicable. This combination of voltage options, safety certifications, and the catalog availability of 28 distinct coil variants makes the series the go-to source for both initial build and maintenance replacement of solenoid coils across the 7019 and 7144 platform.

For OEM machine builders, plant maintenance teams, and procurement managers, having the ability to source the correct replacement coil from a single supplier with a direct part number match to the installed valve eliminates the risk of specifying incompatible aftermarket coils with incorrect magnetic force characteristics, wrong connection geometry, or missing certifications that would void the valve's original CE or ATEX certification.

Maintenance, Repair, and Overhaul

• Plant maintenance programs stocking replacement solenoid coils for installed 7019 and 7144 Series valve fleets to minimize repair lead time when a coil fails in service.
• Valve rebuilding operations at distributor or OEM facilities where matched replacement coils are required to restore valves to original specifications and maintain CE or ATEX certifications.
• Emergency repair situations where having the exact-match OEM coil available on-site reduces unplanned downtime to the minimum time required to perform the coil swap.

Ordering and Model Number Configuration

The Series includes 28 total variants. Filter on the Automatic Valve website by application and voltage to identify the correct coil model for your 7019 or 7144 Series valve.

Verify the voltage and power consumption requirements of the installed valve before ordering a replacement coil. Installing a coil with incorrect voltage can damage the coil and prevent proper valve operation.

For ATEX-classified installations, confirm that the ordered coil carries the required ATEX certification group and temperature class for the hazardous area classification of the installation site.

Frequently Asked Questions (FAQ)

Q: How do I identify the correct replacement coil for my installed valve?

A: Record the coil model number from the label on the installed coil or from the valve assembly nameplate. Cross-reference this against the series product catalog at automaticvalve.com/series/222-solenoid-coils or contact Automatic Valve at (248) 474-6761 with the valve model number for a confirmed coil match.

Q: What voltages are available in the series?

A: The Series includes models for 12 VDC, 24 VDC, 48 VDC, 120 VAC (50/60 Hz), and 240 VAC (50/60 Hz). Filter the available models by voltage on the Automatic Valve website to identify compatible options.

Q: Are ATEX-certified coils available in the series?

A: Yes. Select models within the series carry ATEX certification for Zone 1 and Zone 2 classified areas per ATEX Directive 2014/34/EU. Consult the product catalog for the specific ATEX group and temperature class (T-class) of each certified model to match the requirements of your installation zone.

Q: What is the power consumption of the 7019 Series 24 VDC coil?

A: The 7019 Series 24 VDC coil consumes 4.8 watts in continuous duty operation. The 48 VAC variant consumes 8.5 VA at 50 Hz and 6.9 VA at 60 Hz.

Q: Can I replace just the coil without replacing the entire valve?

A: Yes. Solenoid coils on the 7019 and 7144 Series are field-replaceable components designed to be swapped without removing the valve from the circuit. This allows rapid coil replacement during maintenance without system downtime associated with removing and replacing a complete valve assembly.

Q: Is the series coil rated for continuous duty?

A: Yes. All Series solenoid coils are rated for continuous electrical duty, meaning they can remain energized indefinitely within their rated voltage, current, and temperature envelope without overheating or premature failure.

Q: What is the maximum operating pressure for valves using Series coils?

A: The 7019 Series coils are rated for use with valves operating up to 10 bar (150 psig). The overall system pressure is also limited by the valve body pressure rating, which must be respected concurrently.

Q: Do the coils require any lubrication or periodic maintenance?

A: Solenoid coils are sealed electrical components that do not require lubrication or scheduled maintenance beyond periodic inspection for physical damage, corrosion, and secure electrical connections. Replace coils that show signs of heat damage, insulation cracking, or intermittent electrical operation.

Q: What is the enclosure protection rating of the 7019 Series coils?

A: Refer to the product catalog for the IP (ingress protection) rating of each 7019 Series coil model. Many standard industrial solenoid coils are rated IP65. Contact Automatic Valve at (248) 474-6761 to confirm the IP rating for the specific model of interest.

Q: Can I use a 24 VDC coil on a 12 VDC power supply?

A: No. Operating a solenoid coil at a voltage below its rated specification reduces the magnetic force generated, which may prevent the valve from shifting reliably or at all. Always match the coil voltage rating to the control system supply voltage.

Q: What happens if I energize a solenoid coil above its rated voltage?

A: Over-voltage operation causes excessive current draw, coil overheating, and accelerated insulation degradation. This shortens coil life and can lead to premature failure. Always verify supply voltage matches the coil rating.

Q: How do I order a replacement coil for a valve already in service?

A: Contact Automatic Valve at (248) 474-6761 or visit automaticvalve.com/series/222-solenoid-coils. Provide the valve model number and the voltage of the control system. A product catalog is available on the website for self-service part number identification.

Installation & Maintenance Guidelines

• Depressurize and lockout/tagout the pneumatic system and isolate electrical power to the solenoid before replacing a solenoid coil.
• Verify that the replacement coil voltage matches the control system supply voltage before installation.
• For ATEX installations, confirm that the replacement coil carries the correct ATEX certification for the zone classification of the installation site before installing.
• Remove the electrical connector from the old coil before pulling the coil off the valve. Do not attempt to remove the coil with the connector still attached under tension.
• Slide the new coil onto the valve solenoid stem in the correct orientation as specified in the valve installation instructions.
• Reinstall the coil retaining hardware to the torque specification in the valve installation instructions. Do not over-tighten.
• Reconnect the electrical connector and verify secure engagement with the connector locking mechanism.
• Restore electrical power and actuate the valve with the manual override to verify correct coil function before restoring full system operation.
• Document the coil replacement in the equipment maintenance log, including the replacement coil model number, voltage, and date of installation.
• For stock replenishment, maintain a supply of replacement coils matched to the installed valve fleet to minimize repair lead time on future coil failures.
