Manifold Pressure Regulators H 40 (Hauptdruckminderer)

The Vulkan H 40/300 Effect is a manifold regulator built for manifold systems and direct connection to cylinder bundles where a stable higher outlet pressure is required. In the competitor product line, the H40 series is positioned as a main pressure regulator according to ISO 7291, with single-stage design, inlet pressure compensation for stable downstream pressure as inlet pressure falls, and safety gauges according to DIN EN ISO 5171.

This version is the practical choice for central gas supply installations that need more than a standard 10 or 20 bar regulator can deliver. The regulator combines a brass body, clear dual-gauge pressure indication, and a wide version range for oxygen, argon, CO₂, helium, nitrogen, hydrogen, and compressed air. The result is simple: reliable primary pressure reduction, stable operation, and the right connection standard for the gas in use. The H40 family is specified for up to 300 bar inlet pressure, adjustable outlet pressure up to 40 bar, and maximum flow up to 120 Nm³/h.
