Explosion proof solenoid valves usually require two power lines to operate. Many users purchase them with three wires (three ports) on top. So, how is the wiring method for explosion-proof solenoid valves connected? Refrigeration solenoid valve
1. Wiring method of lead type explosion-proof solenoid valve:
What is a lead type explosion-proof solenoid valve? The lead type means that a power line is led out from the inside of the explosion-proof coil housing. The length of the lead is usually about 1.5 meters, and some outgoing lines can be extended at the factory. So how to wire the lead type explosion-proof solenoid valve? The lead type is a three core wire: the three core wire is divided into yellow, red, (green/black/blue) colors (yellow is the ground wire, red, and green/black/blue are the power lines), and the power supply is not divided into positive and negative poles.
2. Wiring method of explosion-proof solenoid valve with wiring socket:
The explosion-proof solenoid valve terminal block type refers to the three ports inside the explosion-proof coil housing, which are divided into two power lines and one ground line. The terminal block type can directly introduce standard wires into the explosion-proof coil housing for on-site wiring.
