Solenoid 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.

Pilot Valves
Pilot valves are critical for operating larger valves or control actuators in fluid control systems. These valves act as control mechanisms, receiving signals from external devices such as sensors, controllers, or other valves and initiating the opening or closing of the main valve or actuator. Pilot valves are commonly used in applications where high-pressure fluids or significant flow rates are involved, such as hydraulic systems, pneumatic systems, and industrial machinery. They provide reliable and precise control, ensuring efficient operation and safety. With various configurations and actuation methods available, including solenoid-operated, manual, or pilot-operated, pilot valves offer versatility and flexibility to meet specific system requirements.

FAQS
- Use a ball valve for simple on/off shutoff, a control valve when you need to regulate flow rate or pressure, and a check valve to prevent backflow. The choice comes down to whether you need to stop flow, control it, or protect against reverse flow.
- Cv is the flow coefficient — how much water a valve passes at a given pressure drop. Full port means the valve opening matches the pipe diameter for unrestricted flow; regular port is slightly smaller. End connections describe how the valve connects to pipe (NPT threads, flanges, etc.). Body material determines compatibility with your media and environment — brass, stainless, and PVC are the most common.
- Start with your required Cv based on flow rate and pressure drop. Then confirm the valve's pressure and temperature ratings exceed your system's maximums. Undersizing causes excessive pressure drop; oversizing reduces control precision. Always size for your actual operating conditions, not system maximums.
- Fail-open means the valve opens if power or signal is lost; fail-closed means it closes — critical for safety applications. NPT is a threaded connection best for smaller pipes and lower pressures. Flanged connections bolt between pipe flanges and are preferred for larger pipes, high pressure, or applications requiring frequent removal.
- Ball valves use a rotating ball for fast quarter-turn shutoff and are ideal for frequent operation. Gate valves use a rising gate for full open/close and are better for infrequent operation where minimal flow restriction matters. Ball valves are generally more reliable, longer lasting, and easier to operate.
- Because no single valve works well in every application. Pressure, temperature, media type, flow control needs, pipe size, and safety requirements all vary dramatically across industries. Each valve type is engineered to solve a specific set of those problems efficiently.
- Ball valves offer tighter shutoff and are better for smaller lines or where zero leakage matters. Butterfly valves are lighter, more compact, and more cost-effective for larger diameter pipes. For high-volume water flow in large lines, butterfly valves are typically the practical choice.
- Look for stainless steel or carbon steel body construction, graphite or metal seat materials, and valves rated for your specific pressure-temperature combination. Globe valves and ball valves with metal seats are commonly used in high-temp applications. Always verify the valve's published P-T rating before specifying.
- Match the valve type to your application (shutoff, control, or check). Verify body material compatibility with your media. Confirm pressure and temperature ratings exceed operating conditions. Consider end connection type, actuation method, and maintenance requirements. When in doubt, over-specify on pressure rating rather than under.
