NFTA6-1/4SP type pneumatic actuator is widely used in angle-style, double-acting and spring return linear motion systems, thanks to its wear-resistant diaphragm and low static friction. It is ideal for applications such as valve positioner control and damper positioner control in industries such as oil and gas, chemical, and power. In this article, we’ll explore the application field and workings of the NFTA6-1/4SP actuator.

Application Field

The NFTA6-1/4SP actuator is designed to help industries automate valves, dampers, and other linear applications with the most efficient and reliable technology available. It is designed to ensure accurate, repeatable motion with minimal static friction and hysteresis. It has a robust, corrosion-resistant steel frame with a flexible diaphragm for maximum efficiency and performance. This makes it ideal for use in industrial environments with corrosive and extreme temperatures, including offshore and subsea applications.

The NFTA6-1/4SP is suitable for a wide variety of applications, including:

• Oil and gas industry: for valve and damper actuation
• Power industry: for controlling valves in power plants and large boilers
• Chemical industry: for controlling valves and process vessels
• Airports: for controlling air valves and pressure valves

Working Principle

The NFTA6-1/4SP actuator is a double-acting linear pneumatic actuator that relies on the movement of air pressure to power it. It is designed to convert pneumatic energy to mechanical energy, enabling precise, repeatable linear motion with minimal static friction and hysteresis. The actuator consists of an accumulator, which stores air when the actuator is idle and supplies compressed air to the piston when the actuator is in use. The pressurized air then drives the piston, moving the shaft and, ultimately, actuating the valve.

The NFTA6-1/4SP actuator is designed to be low-maintenance, with a corrosion-resistant steel frame and a flexible diaphragm. It also features adjustable end stops, which limit the travel range of the actuator and reduce the risk of overextension. With its low static friction and two-way design, the NFTA6-1/4SP provides reliable and repeatable operation with minimal maintenance.

The NFTA6-1/4SP is an ideal choice for industrial applications, thanks to its robust design and reliable operation. Its wear-resistant diaphragm ensures that it can withstand corrosive and extreme temperatures, making it a great choice for demanding environments such as offshore and subsea.
