NOTE: It is not necessary to remove the valve from the pipeline for repairs.
WARNING: Turn off electrical power supply and depressurize valve before making repairs.
Cleaning
All solenoid valves should be cleaned periodically. The time between cleanings will vary depending on the medium and service conditions. In general, if the voltage to the coil is correct, sluggish valve operation, excessive noise or leakage will indicate that cleaning is required . Clean valve strainer or filter when cleaning the valve.
Preventive Maintenance
1.Keep the medium flowing through the valve as free from dirt and foreign material as possible.
2.While in service, the valve should be operated at least once a month to insure proper opening and closing.
3.Depending on the medium and service conditions, periodic inspection of internal valve parts for damage or excessive wear is recommended. Thoroughly clean all parts. Replace worn or damaged parts. However, for best results, replace all parts as supplied with a Rebuild Kit.
Causes of Improper Operation
1.Faulty Control Circuits: Check the electrical system by energizing the solenoid. A metallic "click" signifies that the solenoid is operating. Absence of the "click" indicates loss of power supply . Check for loose or blown fuses, open circuited or grounded coil, broken lead wires or splice connections.
2.
3.Low Voltage: Check voltage across the coil lead. Voltage must be at least 85% of nameplate rating.
4.Incorrect Pressure: Check valve pressure. Pressure to valve must be within range specified on nameplate.
5.Excessive Leakage: Disassemble valve and clean all parts. If leakage continues, replace all parts as supplied with a Rebuild Kit.
