Valve accessories are additional components that enhance the functionality and performance of valves in fluid control systems. These accessories are designed to provide other features, improve safety, or simplify maintenance of the valves. Valve accessories enhance the reliability, efficiency, and safety of valve operations, making them essential for various industries such as oil and gas, chemical processing, water treatment, and power generation.

Pneumatic actuators are devices that use compressed air to create mechanical motion. They are commonly used to control valves, dampers, or other devices in industrial processes. Pneumatic actuators offer advantages such as fast response, simplicity, and robustness. They find applications in industries such as manufacturing, chemical processing, or oil and gas, enabling reliable and efficient operation.

The 3-piece regular port valve is a versatile and widely used component in fluid control systems, distinguished by its modular construction. Consisting of three separate pieces—the body, bonnet, and trim—this valve design offers several advantages. It facilitates easy maintenance, repair, and modification without requiring the disassembly of the entire valve. Accessing and replacing individual components makes the 3-piece regular port valve highly cost-effective and efficient in industrial applications where downtime must be minimized. Additionally, its modular nature allows for customization and adaptation to specific system requirements. Whether used in chemical processing plants, water treatment facilities, or HVAC systems, the 3-piece regular port valve provides reliable performance and precise fluid regulation, ensuring optimal operation and longevity.

The 1-piece regular port valve represents a streamlined and compact solution for fluid control applications. Unlike its 3-piece counterpart, the 1-piece valve integrates all components into a single unit, simplifying installation and minimizing potential leak points. This design offers straightforward operation and maintenance, making it particularly suitable for applications where space is limited or accessibility is restricted. Despite its simplicity, the 1-piece regular port valve maintains consistent flow rates and reliable performance, ensuring efficient fluid regulation in various industrial and commercial settings. Whether employed in plumbing systems, process piping, or irrigation networks, the 1-piece regular port valve provides a dependable solution for achieving precise control and optimal flow management.

Solenoid Valves

Centro’s solenoid valves deliver fast, accurate, and reliable fluid control across a wide range of applications. These electrically actuated valves regulate the flow of liquids or gases by opening or closing in response to an electrical signal. Known for their rapid switching speed and dependable operation, solenoid valves are integral to industrial automation, HVAC systems, fluid processing equipment, and machinery control.

Centro offers a comprehensive range of solenoid valves engineered to meet the diverse needs of modern systems. Whether you're looking for fail-safe shutoff, continuous flow, or multi-port direction control, we have a solution tailored to your media type, pressure requirements, and operating conditions.

Positioners and limit switches are crucial in various industrial applications, ensuring precise control and safety measures. Positioners are devices designed to accurately control the position of a valve or actuator in response to an input signal. They are commonly used in pneumatic and hydraulic systems to regulate the flow of fluids or gases by adjusting the opening and closing of valves. Positioners enable operators to precisely control the process variables, such as flow rate or pressure, improving industrial operations' efficiency and accuracy. On the other hand, limit switches serve as safety devices that detect the presence or absence of an object and trigger an action when a predetermined limit is reached. These switches are often employed to monitor the position of mechanical components, such as valves, actuators, or machine parts, and ensure that they operate within safe limits. Limit switches can signal the end of travel, prevent overtravel, or initiate emergency shutdown procedures in case of abnormal conditions, enhancing operational safety and protecting equipment from damage. Positioners and limit switches contribute to the reliability, precision, and safety of industrial processes across various sectors, including manufacturing, petrochemicals, and utilities.

Plug valves are durable, versatile quarter-turn valves designed to provide efficient shutoff and precise flow control in a wide range of industries. These valves use a rotating plug, typically cone-shaped or cylindrical, to open or close the passageway, ensuring a tight seal and minimal leakage. Their simple yet effective design makes them ideal for applications requiring reliable performance in high-pressure or high-temperature environments.

Centro offers a comprehensive selection of plug valves to meet the needs of various industries, from chemical processing to water treatment and food and beverage production.
