Pneumatic On-Off Control Valve
ORFA Industrial Products Industry and Trade Inc. distinguishes itself in the industry with its innovative products that provide high-performance control systems for industrial processes. The Pneumatic On-Off Control Valve is designed to meet the highest standards of business needs, featuring advanced technology that enables safe and efficient fluid control.
Pneumatic on-off control valves provide precise control of fluids such as hot water, steam, and gas in various processes. These valves increase energy efficiency and reliably manage fluid flow by operating in either the fully open or fully closed position based on a signal from a controller. Ensuring uninterrupted and loss-free flow is crucial, especially in energy-intensive systems. Thanks to their simple operating principle, these valves offer a user-friendly solution and are easy to use even in complex systems.

Pneumatic On-Off Control Valve - Working Principle
A pneumatic on-off control valve is a type of valve designed to precisely control fluids (liquid, gas, or steam) in industrial processes, either fully open or fully closed. The valve's operating principle is to achieve full open or full close, with no intermediate positions. It consists of "on" (open) and "off" (closed) positions, which allow the fluid to either flow freely or to remain completely closed.
Pneumatic Control Mechanism:
A pneumatic on-off control valve, as its name suggests, operates using air pressure. Air pressure is used by a pneumatic actuator (moving mechanism) to open or close the valve. This actuator, in turn, activates a diaphragm, piston, or multi-spring mechanism attached to the valve body, which in turn moves the valve plug, which controls the flow of fluid. This movement allows the valve to be fully open or fully closed.
Opening and Closing Operation:
Open State: When the valve needs to be opened, a control signal sends air pressure to the pneumatic actuator. The air pressure tensions the spring mechanism, lifting the valve plug and fully opening the valve opening. This allows fluid to flow freely through the valve. The valve opening time may vary depending on the actuator's capacity and the strength of the air pressure connected to the system.
Closed (Off) State: When the close command is received, the air pressure in the pneumatic system is cut off, and the spring mechanism is activated. This spring pushes the valve plug back, closing the valve. The valve plug seats tightly against the sealing surface in the valve body, completely stopping the flow of fluid. This ensures a controlled shut-off of fluid flow in the system.
Advantages of On-Off Working Principle:
The simple yet effective operating principle of pneumatic on-off control valves ensures high efficiency, particularly in industrial processes requiring frequent on-off switching. On-off valves offer an ideal solution for processes that do not require intermediate positions. These valves offer the following advantages:
Fast Response Time: Thanks to the pneumatic mechanism, the valve can open and close quickly. This feature is especially important in processes requiring sudden opening or closing.
Low Energy Consumption: Pneumatic systems consume less energy than electric systems, which reduces operating costs.
High Reliability: Since the valve is in either the fully closed or fully open position, control of the fluid is extremely reliable and the risk of leakage is minimized.
Easy Use and Maintenance: These valves operate on the On-Off principle and are easy to use and maintain thanks to their simple structure.
Areas of Use:
Pneumatic on-off control valves are used in many industries where precise fluid flow control is crucial. These valves are commonly preferred in demanding processes such as chemical, energy, oil and gas production, and water treatment. These valves operate according to process pressure and temperature conditions, allowing for optimal flow rate adjustment. Thanks to their spring-loaded mechanism, these valves provide high performance across a variety of pressure ranges, increasing business efficiency and improving production processes.
ORFA 's Pneumatic On-Off Control Valve, with its reliability, long-lasting design, and superior material quality, is an ideal choice for uninterrupted performance in industrial facilities. Offering significant advantages, particularly in terms of energy savings and process efficiency, this product is the perfect solution to meet your business needs.
