Description
JW100 series semi-automatic changeover manifold with diaphragm valves is designed for continuous, safe delivery of high-pressure specialty gases in industrial and laboratory environments. The diaphragm valve isolates the gas path, minimizing leakage and contamination and providing low internal volume suitable for high-purity applications. The panel integrates regulators, gauges and changeover logic to maintain stable outlet pressure under varying inlet conditions up to 3000 psi.

Additional Notes
Suitable for twin high-pressure gas cylinders with automatic changeover and purging function. Constructed and tested for corrosion resistance; assembly and leak testing performed in clean workshop conditions. Typical use: laboratories, gas analysis, high-purity supply.
