Parker Lucifer E131K03 Solenoid Valve

Overview

The Parker Lucifer E131K03 solenoid valve is a direct acting valve from the Lucifer K-series, supplied here as the 3/2-way normally closed version identified in the original listing. The valve has a G1/4 female threaded connection and a brass body, and the original listing identifies the configuration as 24 V dc, IP65, orifice 2.5 mm, working pressure 0-7 bar and flow factor 3.5 L/min.

Direct acting solenoid valves are used where the valve must operate reliably at zero differential pressure, since the solenoid moves the valve directly without relying on the line pressure. The K-series E131K03 is a compact brass valve suitable for air, gas and liquid media in control circuits.

Engineering & Design

In a direct acting valve the solenoid armature is coupled directly to the valve seat, so the valve opens and closes on the solenoid force alone. The E131K03 solenoid valve is a 3/2-way normally closed valve: when the coil is energised the valve switches, and when the coil is de-energised a spring returns it to the closed position.

The valve body is brass with FKM (Viton) seals, and the working temperature range is -10 °C to +100 °C for the fluid, with a maximum operating pressure differential of 7 bar as stated in the original listing. The assembly reference of this example follows the E131K03-492453 configuration with the C2H coil code per the original listing.

• General machine and process control
• Replacement duty for existing E131K03 valves

Specifications

Compatibility & Integration

The E131K03 solenoid valve connects into the fluid circuit with its G1/4 female threads and to the control circuit with the solenoid coil, which for this example is a 24 V dc coil directly compatible with PLC and relay outputs. The direct acting design means the valve works even with no pressure differential, which is important for vent and drain applications.

Before installation, confirm the media, temperature and pressure of the circuit against the valve rating, and check the compatibility of the FKM seals with the media used. Our team can confirm the configuration against your application before dispatch.

FAQ

Identifying the Valve from the Nameplate

Lucifer valves carry the valve type on the body or label, and the coil has its own code and voltage marking. When replacing an installed E131K03 solenoid valve, record both the valve code (including any assembly suffix such as -492453) and the coil label, then confirm:

• Valve function – 3/2-way normally closed – and the port marking used in the circuit
• Coil voltage and type (AC or DC) and the connector style
• Media, pressure and temperature of the application against the valve rating
• Seal material compatibility with the medium

Valve Installation and Commissioning

Flush the pipework before installation, since particles are the most common cause of leaking seats in small-orifice direct acting valves, and fit a strainer upstream where the medium is not clean. Connect the ports according to the body markings, use suitable thread sealing on the G1/4 connections without letting sealant enter the valve, and never use the coil as a lever when tightening. Wire the coil for the correct voltage and make sure the connector gasket is in place to keep the IP65 rating. On commissioning, cycle the valve several times and check for leakage at the exhaust port in the de-energised state.

Maintenance and Troubleshooting

• Valve does not switch – check coil voltage at the connector, coil continuity, and whether the pressure differential exceeds the rating
• Leakage through the exhaust – dirt on the seat or worn seals
• Coil overheating – wrong voltage, or a continuously energised coil in high ambient temperature
• Humming or slow response – usually an AC coil issue; check that the correct coil is fitted

Applications in Oman and the GCC

Direct acting 3/2-way valves are used in pneumatic pilot circuits for actuators, instrument air control and small machine functions across the region’s oil and gas, water and manufacturing plants. Seven Star LLC supplies Parker Lucifer valves and coils as complete units or spares, checked against your nameplate data before dispatch.
