Valves - Fisher

Control valves regulate the flow, pressure, and temperature of fluids in various industrial processes. These valves are essential for maintaining efficiency, safety, and precision in applications such as oil and gas, chemical processing, water treatment, food and beverage, and manufacturing. Centro offers a wide selection of control valves designed to meet the demands of these industries.

Types of Control Valves

Centro provides various control valves to suit different applications, including:

• Needle valves for precise flow control in instrumentation and low-flow systems.
• Flow control valves to regulate fluid flow and maintain system stability.
• Pneumatic globe control valves for automated, high-efficiency operation.

Choosing the Right Control Valve

When selecting a control valve, it’s important to consider factors such as the type of fluid (liquid, gas, or steam), operating pressure and temperature, flow rate requirements, and system compatibility. Whether you need a manually operated valve or an automated solution, Centro offers high-performance options to meet your needs.

Valve positioners are used to achieve precise control in industrial applications where the flow of liquids, gases, or steam needs to be accurately regulated. These devices adjust the valve actuator's position based on input signals, ensuring optimal performance and efficiency in process control systems.

Types of Valve Positioners

Centro offers a full range of valve positioners to meet various industry needs, including:

• Pneumatic valve positioners—These use air pressure to adjust valve positions, and they are ideal for applications requiring fast and reliable control.
• I/P valve positioners (current-to-pressure) – Convert electrical signals (4-20mA) into pneumatic pressure to precisely control valve actuation.
• Electro-pneumatic positioners – Combine electrical and pneumatic inputs for enhanced control in automated systems.

Choosing the Right Valve Positioner

Selecting the right valve positioner depends on factors such as:

• The type of actuator (linear or rotary)
• Control signal requirements (pneumatic, electric, or hybrid)
• Environmental conditions, such as temperature and pressure
• Desired precision and response time

Why Choose Centro for Valve Positioners?

• Extensive selection of valve positioners, including pneumatic and I/P models.
