Solenoid Valves - Apollo Valves
Solenoid valves provide fast, reliable on/off control of water, air, gas, oil, steam and chemicals using an electrical signal. They automate filling, dispensing, cooling, cleaning and safety shutoff in countless machines and systems.
Solenoid Valve Types
- 2-way valves – simple open/close flow control
- 3-way and 4-way valves – divert flow or operate actuators
- Direct-acting valves – work from zero pressure
- Pilot-operated valves – larger flows at line pressure
- Specialty valves – steam, fuel gas, cryogenic and proportional
Choosing a Solenoid Valve
Confirm the media, pressure range (including minimum pressure differential), temperature, port size and Cv. Choose body and seal materials compatible with the fluid, and select a coil voltage and enclosure rating for the location. Normally closed or normally open depends on the fail-safe state you need.
Centro carries solenoid valves for water, air, steam, gas and process applications.

- A solenoid valve is an electrically operated valve that controls the flow of liquids or gases. It uses an electromagnetic coil to open or close the valve automatically when energized.
- When electrical current flows through the solenoid coil, it creates a magnetic field that moves an internal plunger. This movement opens or closes the valve, allowing or stopping flow.
- Common types include normally closed (NC), normally open (NO), direct acting, pilot operated, two way, three way, and four way solenoid valves.
- Solenoid valves are commonly made with brass or stainless-steel bodies, and sometimes plastic (PVC, PP, PVDF) for chemical service. Internal parts are typically stainless steel, and the seals are usually NBR (Buna-N), EPDM, FKM (Viton), or PTFE (Teflon) depending on the fluid and temperature.
- Solenoid valves can handle water, air, steam, oil, fuels, and many chemicals. Fluid compatibility depends on valve body material and seal selection.
