What is a general purpose solenoid valve?
General purpose solenoid valves are versatile valves designed for on/off control of common fluids such as water, air, light oils, and neutral gases. They are widely used in water purifiers, irrigation systems, automatic filling machines, washing systems, cooling circuits, and the water and air lines of industrial machinery. The category includes Tork models with various connection sizes and operating principles.
Model types
- Direct-acting, normally closed: Operates even on pressureless or low-pressure lines; for small-bore applications.
- Direct-acting, normally open: For lines where flow must continue when power is cut.
- Pilot-operated, normally closed: For opening large valves with a small coil on high-flow lines.
- Pilot-operated, normally open: For high-flow lines that must remain open when de-energized.
Codes in product names (e.g., S1021, S1040) identify the model; NO and NC indicate the valve's de-energized position.
Selection criteria
The minimum and maximum pressure values in the line must be determined; pilot-operated valves will not open without a minimum pressure differential. The fluid temperature must not exceed the resistance of the seal material. The connection size must match the pipe diameter and have sufficient flow capacity for the required flow rate. The coil voltage and type (AC or DC) must be selected to match the control panel.
Installation and maintenance
Installing a Y-strainer upstream of the valve protects the seals from sand and sediment. Pay attention to the flow direction arrow; do not overtighten the valve body when connecting to the pipe. Valves that have not been operated for a long time may seize due to scale buildup; periodic operation is recommended. When leakage is observed, the valve seal and core should be cleaned or a repair kit should be used.
Frequently asked questions
Can a general purpose valve be used with hot water?
It can be used up to the temperature limit that the seal material can withstand. For steam and high temperatures, steam solenoid valves should be selected.
Can it be used in a booster pump system?
It can be used in booster pump and tank filling lines within the appropriate pressure range.
Can it be used on a natural gas line?
Only gas valves approved for that specific use must be used on gas lines.
Should I choose NO or NC?
If flow must stop when power is cut, choose NC; if flow must continue, choose NO.
Why won't the valve open?
The coil may not be receiving power, the coil may have burned out, or in a pilot-operated valve the pressure differential may be insufficient.
How is the coil voltage selected?
It is selected according to the voltage of the control circuit. An incorrect voltage can burn out the coil in a short time.
