Control Valves
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.

ECONO/HAT-RA is primarily used for thermal relief on booster pumps to keep them cool during idling. Since ECONO/HAT-RA valves open on rising temperatures, they can be used in many other thermal relief valve applications. These valves save space, install in seconds, and eliminate the use of extra, expensive, and time-consuming piping. The unique ram-type plug & seat provide a reliable, tight shut-off longer than any other design available.

FAQS
- A control valve is a mechanical device used to regulate flow, pressure, temperature, or liquid level in a system. It automatically adjusts valve position in response to signals from a controller.
- Control valves receive a signal from a controller or sensor and modulate the valve opening to maintain desired process conditions such as flow rate or pressure.
- Common types include globe valves, ball control valves, butterfly control valves, diaphragm control valves, pinch valves, and angle valves.
- Control valves may use pneumatic, electric, or hydraulic actuators. Pneumatic actuators are common in industrial environments due to reliability and safety.
- Flow characteristic describes the relationship between the valve's stem position (% open) and the flow rate through it (% of maximum flow), and it determines how the valve responds as it opens. A linear flow characteristic means the flow rate is directly proportional to valve position — 50% open gives 50% flow, 25% open gives 25% flow. Linear valves are used in applications with a constant pressure drop where a proportional response is needed, such as liquid level control loops and some blending or batching applications. An equal-percentage flow characteristic means equal increments of valve travel produce equal percentage changes in flow — so at low openings, small position changes produce small flow changes, and at high openings, the same position changes produce much larger flow changes. This provides better control in applications where the pressure drop across the valve changes significantly with flow rate (which is the case in most industrial process loops), because the valve's increasing gain at higher openings compensates for the decreasing pressure drop. Equal percentage is the most commonly specified characteristic for process control applications because it provides the most stable control across the widest range of operating conditions.
