HORNUNG GMBH

Miniature Pressure Reducer with Inlet Pressure Compensation
PCTFE Seat Seal
Diaphragm made of 1.4435 / Hastelloy
Pressure Gauge with Safety Design per EN 837-1 Class 1.6

The HP 104 cylinder pressure reducer is a single-stage pressure regulator—constructed from electropolished stainless steel (1.4404) or nickel- and chrome-plated brass—designed for gas withdrawal from individual cylinders, particularly lecture bottles and small steel cylinders. It is especially suitable for mobile field or laboratory applications and ensures a consistently constant working pressure throughout the entire cylinder depletion process. The pressure reducer comes equipped as standard with a gas-specific hand-tight cylinder connection compliant with DIN 477, allowing for tool-free installation. Certified according to ISO 9001:2008 and ISO 14001:2009, it offers precise pressure regulation and exact gas shut-off capabilities, enabling finely controllable gas withdrawal.
