Solenoid valves are critical components in automated systems, controlling the flow of liquids and gases. Selecting the appropriate valve ensures system efficiency, reliability, and safety. This guide will help you navigate the key considerations for choosing the best solenoid valve for your industrial applications.
FAST RESPONSE, OPENS FROM 0 BAR: A semi-direct design opens from 0 bar with no minimum pressure differential and switches open or closed in under 1 second when energized or de-energized, rated for over 1 million cycles
INDUSTRIAL BRASS, FOR FUEL GAS AND OIL: A corrosion-resistant brass body suits gasoline, diesel, kerosene, natural gas, air, and oils; because brass contains lead, do not use it for drinking water
FKM SEAL FOR HEAT AND FUEL: The FKM (fluoroelastomer) seal resists high temperatures and corrosive chemicals, fuels, oils, and lubricants over -10 to 120 °C (14 to 248 °F) where NBR or EPDM seals would swell
NORMALLY CLOSED, NOT CONTINUOUS DUTY: An internal spring holds it closed with no power; energize the DC 12 V coil (20 W) to open. Not a continuous-duty valve, so limit energizing to 8 hours per cycle to protect the coil
-NEW- Re-engineered low power coil with up to 50% less heat generation. The valve starts as 19W and as it heat up to operating temperature power reduces to approx. 10-13W.
Constructed of industrial grade brass, this valve is corrosion resistant, more conducive for welding, optimal for higher temperature projects, and can be used with gasoline, diesel fuel, kerosene oil, natural gas, air etc. Due to the chemical composition...
This valve was manufactured with a VITON seal. VITON is the most durable and high performance rubber material with the ability to resist high temperatures and corrosive chemicals and other fluids like gasoline, diesel fuel, oils, and lubricants.
This highly responsive valve will open and close in less than 1 second when actuated; meaning it will open or close the flow instantaneously when energized or de-energized. Also, our U.S. SOLID engineers have determined that the life cycle of this valve...

PLEASE NOTE: This valve is NOT a continuous duty valve and should NOT be in continuous use for more than 8 hours in a single cycle; to do so will shorten the life of the valve and may cause the core of the valve to burn out. If you need a continuous duty...

How to Choose the Best Solenoid Valves
Environmental and Application Factors
The environment in which the solenoid valve will operate significantly influences the choice. For corrosive fluids or harsh environments, stainless steel or specialized plastic bodies are recommended. If the valve is exposed to moisture or dust, ensure it has an appropriate IP (Ingress Protection) rating for adequate sealing. Hazardous locations may require intrinsically safe or explosion-proof designs. Consider the temperature range of both the fluid and the ambient environment to prevent malfunction or premature wear.
Frequently Asked Questions
What is the difference between a 2-way and a 3-way solenoid valve?
A 2-way valve has two ports and is used to start or stop flow. A 3-way valve has three ports and can be used to direct flow between two different paths or to act as a diverter or selector.
How do I determine the correct orifice size?
The orifice size determines the flow rate capacity. It should be selected based on the required flow rate at the system's operating pressure. Consult flow charts or manufacturer specifications for guidance.
What does 'pilot-operated' mean for a solenoid valve?
Pilot-operated valves use the pressure of the fluid within the system to help open or close the main valve orifice. This allows them to handle higher pressures and flow rates more efficiently than direct-acting valves.
Can I use an AC voltage valve with a DC power supply?
No, you should not. AC and DC voltages are not interchangeable. Using the wrong voltage type can damage the solenoid coil and render the valve inoperable.
What is an IP rating?
An IP (Ingress Protection) rating indicates the degree of protection provided by the valve's enclosure against solid objects and liquids. Higher numbers signify better protection against dust and water intrusion.
