Norgren VHLA400-04G Rotary Lever Valve - G1/2
Part Number: VHLA400-04G
Quick Summary
The VHLA400-04G is a manual rotary lever valve designed for precise air control in compact automation systems. Engineers often struggle with awkward actuation and limited access in space-constrained panels; this valve delivers a detented centre position, a 2/3 position function, and a panel mounting option to simplify installation and service. Certification details such as CE marking, SIL safety integration, or IP ratings are not listed in the provided data; please verify against the official datasheet. With a rugged aluminium body and nitrile seals, the VHLA400-04G delivers reliable, low-maintenance performance, while compatibility with Pneufit C fittings and standard G1/2 ports supports rapid deployment in manufacturing lines. For designers and maintenance teams, the combination of detented positions and robust construction translates into fewer mispositions, faster setup, and longer service intervals.

The VHLA400-04G provides a 4/3 valve with APB function and lever actuation, delivering direct manual control with a simple tactile interface that reduces operator errors and shortens changeovers in busy lines. This configuration is well suited to automation lines, bench tests, and compact pneumatic circuits where quick, repeatable manual overrides are required. The valve also features a detented centre position and 2/3 position options, which translates to repeatable endpoints and faster cycle verification, minimizing downtime during line changes and setup. Panel mounting compatibility, supported by the VHLA-400N mounting nut, simplifies installation in control panels and machine frames, reducing wiring complexity and post-installation adjustments. The rugged aluminium body and nitrile seals provide durable, leak-resistant performance across standard industrial environments, while G1/2 ports and a 0–9.7 bar operating range enable broad system integration. Finally, ready-made fittings and tubing options from Pneufit C family (C02251248, C02471248) and PA2 tubing support rapid commissioning and reliable air delivery with minimized dead volume.

FAQs
Install the VHLA400-04G using its G1/2 ports and the optional panel mounting kit. Secure with the VHLA-400N mounting nut, align the lever for easy access, and connect air lines via Pneufit C fittings such as C02251248 or C02471248 to minimize dead volume, ensure reliable seals, and simplify maintenance.
The valve supports up to 0–9.7 bar (0–141 psi) operating pressure and delivers a flow of about 3100 L/min (109 scfm). It operates effectively in -5 to 60 °C environments, making it suitable for typical industrial machinery and automation lines needing reliable pneumatic actuation.
Yes. The VHLA400-04G is designed for compatibility with Pneufit C push-in fittings, including C02251248 (straight adaptor) and C02471248 (90° swivel elbow), and PA2 tubing options such as PA2-0012025C and PA2-0012100 for ready-to-run assemblies, which reduces installation time and leak risk.
The valve supports panel mounting via the VHLA-400N mounting nut, allowing secure, space-saving installation in control panels. This enables easier service access and reduces wiring complexity, which is especially beneficial for retrofits and compact machine builds.
Regular inspection of the detented lever action and seals is advised. The nitrile seals and aluminium body offer robust durability, but periodic checks for leaks and proper mounting tension help maintain performance in daily operation. Refer to the official datasheet for recommended service intervals and replacement part numbers.
