Norgren Roller Pneumatic Manual Control Valve, 3/2 Way, G 1/8, Polyamide Body, 10 Bar, 335L/min, 03 Series 03040202

The Norgren 03040202 Roller Pneumatic Manual Control Valve is a specialized 3/2 way valve designed for demanding pneumatic applications in industrial automation, manufacturing, automotive, and process control sectors. Featuring a robust construction with a polyamide body, this manual valve utilizes a roller-plunger actuation mechanism that enables precise directional airflow control. The roller allows the valve to be operated by contact with a cam or moving part within a machine, making it highly suitable for automated systems requiring quick and automatic response.

With a G 1/8 standard threaded port, the valve integrates seamlessly into a wide range of pneumatic circuits. The 3/2 configuration offers two outlet ports and one inlet port, supporting both supply and exhaust control in bidirectional operations. Its high maximum operating pressure of 10 bar allows compatibility with heavy-duty systems, while a maximum flow rate of 335 L/min efficiently manages air supply to downstream devices. The internal mechanism utilizes reliable nitrile rubber seals to prevent ingress of dust and particulates, thus maintaining optimal system performance even in challenging environments.

The roller-plunger actuation is spring-loaded and self-resetting, providing quick return to its original position after actuation. As a result, the Norgren 03040202 valve is particularly valued in high-speed and repetitive-motion environments, such as production lines, assembly systems, and automated machinery. The polyamide construction offers high mechanical resistance, abrasion durability, and a lightweight form factor (approximately 60 g) for ease of installation and long service life.

Color-coded switch/button options (red, green, black) aid in operator safety and machine interface clarity. Operating reliably across a temperature range of 0 °C to 50 °C, this manual control valve can be deployed in temperature-variable industrial environments. A compact physical profile - 81 mm length, 45 mm width, and 21 mm height - accommodates installation in space-limited panels or machinery.

The Norgren 03040202 Roller Manual Control Valve is extensively used in pneumatic automation, automotive assembly, medical and pharmaceutical manufacturing, process machinery, and industrial maintenance systems, where precise, responsive, and rugged manual flow actuation is required. Its adherence to standard interfaces and robust polyamide body ensures long-term operational reliability while facilitating integration into existing pneumatic infrastructure.
