Norgren VHLA402-04G Valve - G1/2, 4/2 Lever Actuated
Part Number: VHLA402-04G
Quick Summary
Norgren VHLA402-04G is a compact manual rotary lever valve for compressed air control in automation. Operators and engineers often face space constraints, awkward handling, and downtime from valves that are slow to operate or misalign during cycling. Note: The data does not specify SIL, CE or IP ratings for this model; verify certification coverage in the datasheet or with your Norgren distributor. With panel mounting options and a detented centre, this valve delivers repeatable positioning and quick actuation, helping to reduce setup time and errors in pneumatic circuits. Designed for robust factory environments, it supports 0–9.7 bar pressures and -5 to 60 C temperatures, enabling predictable operation in automation lines, packaging, robotics, and handling systems.

FAQs
Install VHLA402-04G using the VHLA-400N Panel Mounting Nut for secure panel integration. Align the valve ports with the pneumatic manifold, tighten mounting hardware to prevent movement, and connect the Pneufit C fittings (C02471248 or C02251248) for clean push-in connections. Verify panel clearance and ensure the lever operates freely through its detented centre to avoid mispositioning.
The valve supports operating pressures from 0 to 9.7 bar (0 to 141 psi) and is designed for use with compressed air. For best performance, use clean, dry air and ensure the supply meets the required filtration and moisture control standards to protect nitrile seals and aluminium housing from premature wear.
A 4/2 valve has four ports and two switch positions, providing two active flow paths in each position. Lever/lever actuation means manual control from either side, with a detented centre to hold the valve in the default position. This combination supports intuitive operation, repeatable cycles, and rapid manual override in automation tasks.
Yes, with a flow rating of 3100 l/m (109 scfm), the VHLA402-04G accommodates relatively high-throughput pneumatic circuits for compact panels. Pair this with a 0–9.7 bar supply to ensure consistent actuation times. The aluminium body and nitrile seals support reliable performance across typical factory environments.
Regularly inspect the aluminium body for signs of corrosion or wear, and check nitrile seals for cracking or leakage. Verify lever movement is smooth and detent function is active. Replace seals if leakage or performance degradation is observed. Use standard VHLA accessories (VHLA-400N mounting nut, Pneufit C fittings) to maintain proper assembly alignment and seal integrity.
