Proportional Control Valves

Proportional control valves are one of the most critical components of automation systems, precisely adjusting the flow rate, pressure, or temperature of fluids in industrial processes according to incoming signals. ORFA Industrial offers electric and pneumatic actuated proportional control valves that operate with millimeter precision in steam, gas, and liquid lines, backed by extensive stock advantages. Professional proportional control valves, distinguished by their high response speed and excellent sealing performance, ensure process stability and energy savings with ORFA quality.

What Are Proportional Control Valves and Their Working Principle

Proportional control valves are valve types that change the disc opening proportionally according to control signals such as 4-20 mA or 0-10V, with the help of a positioner or actuator. Unlike on-off valves, these proportional control valves allow the flow to be kept constant at any desired value or changed gradually. ORFA Industrial recommends the use of professional proportional control valves to increase system efficiency in precision heating-cooling cycles and chemical dosing lines. These proportional control valves, capable of managing process variables in real-time, ensure sustainability in production quality. Equipped with high-strength internal parts, quality proportional control valves maintain precision even under dynamic loads, maximizing operational safety.

Types and Designs of Proportional Control Valves

Different proportional control valve models are available in our stock depending on the system's actuation source and the physical state of the fluid. The main proportional control valve product groups offered at ORFA are as follows:

Choosing the Right Proportional Control Valves

The performance of an automation system is directly dependent on selecting proportional control valves suitable for the fluid characteristic and Kvs value. Incorrect valve size selection can cause cavitation or inadequate rangeability on proportional control valves. With ORFA engineering support, we determine the most durable proportional control valve configuration needed for your project based on technical data. These proportional control valves, equipped with modern positioner technology, reduce your energy costs with low air or electricity consumption. A professional proportional control valve investment standardizes product quality while minimizing waste rates. With quality proportional control valves, bringing critical flow processes in your facility under full control is now much safer.
