Goetze Armaturen Safety and Pressure Reducing Valves

Engineering Heritage of Goetze KG Armaturen (German Manufacturing Since 1949)

Goetze KG Armaturen began its manufacturing journey on 15 September 1949, when master engineer Gerhard Goetze established a specialized factory in Ludwigsburg (Baden-Wuerttemberg, Germany).

Dedicated to the precision production of high-performance pressure control and safety valves, the enterprise rapidly gained acclaim among industrial plant builders throughout Europe.

Over more than seven decades of uninterrupted development, the family-managed firm expanded into a premier technology pioneer, establishing international branches across Europe, North America, and Asia, and constructing a unified corporate campus in Ludwigsburg that unites development, fabrication, and cleanroom assembly under a single roof.

Headquartered in Ludwigsburg, Goetze operates under rigorous industrial quality control protocols.

Advanced multi-axis CNC milling of gunmetal and high-alloy stainless steel, laser sealing of pressurized diaphragms, and automated computer-monitored hydrostatic test benches verify pressure settings and seat tightness before shipment.

Goetze valves serve mission-critical roles in thermal power generation, hydrogen energy infrastructures, chemical synthesis plants, and municipal water utilities across more than sixty industrial nations.

Operating Principles and Design of Safety Valves: Series 851 and 451

Goetze spring-loaded safety valves protect pressurized vessels, steam piping, and hydraulic systems against unsafe pressure surges. When the inlet force exceeds the preset spring counter-force, the valve disc lifts instantly, discharging the excess medium through the angled outlet port.

Series 851 valves constructed from corrosion-resistant gunmetal CC499K deliver dependable overpressure defense up to 50 bar for neutral fluids, steam, and compressed air, available with lifting levers or gastight caps.

For severe chemical processing, petrochemical refining, and cryogenic gas handling, Goetze engineers the series 451 and 455 full-lift valves machined from solid 1.4404 (316L) stainless steel.

Featuring metallic or resilient sealing elements, these robust units accommodate set pressures up to 70 bar and withstand process temperatures ranging from -200 to +400 degrees Celsius without calibration shift or mechanical deformation.

Industrial Pressure Reducing Valves: Series 681 and Lead-Free 9000 Platform

Goetze direct-acting pressure reducing valves (series 681, 481, and 9000) deliver reliable downstream pressure stabilization without auxiliary energy or external pilot lines.

The internal mechanism balances inlet forces via a calibrated spring opposed by a flexible elastomer diaphragm or stainless piston.

When demand fluctuates or upstream pressure surges up to 40 bar, the balanced valve plug modulates instantly to sustain an unvarying outlet setting between 0.5 and 15 bar.

For drinking water networks and pharmaceutical lines, Goetze manufactures the series 9000 and 9040 lead-free gunmetal pressure reducers. Designed to meet strict sanitary standards, these valves prevent heavy metal leaching into pure water.

The integrated sediment strainer protects downstream instruments, while the user-friendly adjustment handwheel allows prompt setpoint calibration on site.

Proportional Overflow and Bypass Control Valves: Series 618 and 418

Proportional overflow valves Goetze series 618 and 418 fulfill an indispensable protective role in closed circulation loops, preventing pump overheating and dead-head stall when downstream shut-off devices close unexpectedly.

Unlike sudden pop-action safety valves, these proportional units open progressively in direct proportion to upstream pressure elevation, diverting fluid into the bypass return line.

This proportional relief action dampens fluid hammer shockwaves, protects mechanical pump seals from pressure spikes, and eliminates cavitation wear on impellers.

Available in gunmetal CC499K and 1.4404 stainless steel with thread connections from G 3/8 to G 2 inches, series 618 valves offer adjustable setpoints from 0.2 to 20 bar for industrial machine cooling, testing benches, and fluid filtration systems.

Hygienic Diaphragm Valves Series 4000 and Cryogenic Valves Series 2400

For demanding specialized industries, Goetze engineers purpose-built valve platforms that master extreme operating conditions. The hygienic series 4000 features electropolished internal flow passages with surface roughness below Ra 0.375 um and sanitary Tri-Clamp or aseptic flange connections.

Engineered for biotechnology fermenters, autoclaves, and food processors, these valves withstand automated CIP washdown and high-temperature steam SIP sterilization.

For liquefied technical gases, Goetze supplies the series 2400 and 2700 cryogenic valves.

Equipped with an extended bonnet and hermetic stainless steel bellows, the design insulates the spring chamber against extreme frost, guaranteeing reliable overpressure relief for liquid nitrogen, oxygen, and liquefied natural gas down to -270 degrees Celsius.
