ZOLOTO Bronze Union Bonnet Globe Valve (flanged)

The Zoloto 1032 Bronze Union Bonnet Globe Valve (Flanged) is high-performance flow control equipment engineered for severe-service piping systems. Manufactured with corrosion-resistant bronze and renewable 13% Chromium Stainless Steel internal components, this flanged globe valve provides exceptional shut-off precision and throttling capability under elevated working pressures.

Core Engineering Highlights

• Flanged Connection: Ends feature BS 10 Table 'F' flanging for seamless inline bolting and uniform pressure distribution across pipe joints.
• Union Bonnet Architecture: Constructed with a screwed-on bonnet and a rising stem mechanism, ensuring structural stability through thermal cycles.
• In-Line Repacking Mechanism: Features an back-seating capability that allows engineers to repack the gland safely while the system is fully pressurized.
• Heavy-Duty SS 410 Working Parts: Core internal elements—including the valve disc, stem, and body seat ring—are built from renewable ASTM A276 Type 410 Stainless Steel to resist wear and cavitation.
• Manual Control: Driven by an ergonomic Cast Iron handwheel (IS 210 Gr. FG 200) for smooth torque output.

Technical Pressure & Temperature Ratings

• Hydrostatic Shell Test: 35 kg/cm²g (500 psig)
• Working Steam Pressure: 10.55 kg/cm²g (150 psig) 
• Maximum Temperature Threshold: 225°C → 225 degrees Celsius
  
  

Media Applications & Compatibility

• Steam Service: Optimized for low-to-medium steam lines and boiler feedwater piping.
• Water & Fluid Networks: Ideal for commercial water distribution and process cooling lines.
• Oil Processing: Efficiently handles fuel oil, lubricants, and non-corrosive hydrocarbons.
• Air & Compressed Gases: Fully compatible with standard gas loops; an optional PTFE seating configuration is available for specialty gas sealing needs.
