Check valves are mechanical devices designed to allow fluid—whether liquid or gas—to flow in only one direction, preventing backflow that can damage equipment or disrupt system performance. Commonly used in industrial, plumbing, and MRO (maintenance, repair, and operations) systems, they automatically open with forward flow and close when flow reverses. Available in various types like swing, ball, and inline designs, check valves are essential for ensuring system integrity, protecting pumps and compressors, and maintaining operational safety.

Types of Check Valves We Offer:

• Swing Check Valves – Ideal for irrigation and low-pressure systems
• Ball Check Valves – Reliable for wastewater and slurry applications
• Piston Check Valves – Designed for precise flow control in hydraulic systems

Centro partners with leading manufacturers to provide top-quality materials and engineering in every check valve we supply. Browse our extensive selection and find the perfect check valve for your needs. Order online today or contact our experts for assistance!

Needle valves are essential for controlling fluid flow with high precision in industrial and commercial applications. These valves feature a small, tapered stem that allows for fine adjustments, making them ideal for systems that require accurate flow regulation. Commonly used in industries such as chemical processing, oil and gas, water treatment, and instrumentation, needle valves help maintain efficiency and process stability.

Types of Needle Valves

Centro offers a variety of needle valves designed to meet different application requirements, including:

• Standard needle valves for general-purpose flow control in low- to medium-pressure systems.
• High-pressure needle valves built for demanding applications with extreme pressure conditions.
• Instrumentation needle valves for precise flow adjustments in analytical and laboratory settings.

Choosing the Right Needle Valve

Selecting the appropriate needle valve depends on factors such as system pressure, temperature, fluid type, and required flow control precision. Consider whether the valve needs to handle gases or liquids, as well as the level of adjustability required for your application.

Flow control valves are essential devices used in fluid control systems to regulate the flow rate within a pipeline or system. These valves allow for precise adjustment of flow rates, ensuring optimal performance and efficiency. By controlling the opening or closing of the valve or by using throttling mechanisms, flow control valves can increase or decrease the flow rate as desired. This enables operators to maintain stable flow conditions, prevent fluid overload, and achieve accurate flow control for various applications. Flow control valves are commonly used in manufacturing, oil and gas, water treatment, and HVAC systems, where precise flow management is critical for operational success.

Pneumatic control valves are essential components used in pneumatic systems to regulate and control the flow of compressed air or gas. These valves are crucial in various industrial applications, including automation, manufacturing, and process control. Pneumatic control valves are designed to receive signals from pneumatic controllers or other control devices, allowing for precise airflow, pressure, and direction adjustment. By opening or closing specific ports or channels, these valves enable the efficient control of pneumatic actuators, such as cylinders or motors. They offer fast response times, high repeatability, and reliable operation, making them ideal for applications requiring precise and dynamic control of pneumatic systems.
