Technical purpose The declared products are HERZ ball valves with extended plastic T-handle (models 1 2201 XX and 1 2206 XX). This is a group of similar products that mainly differ in nominal diameter (DN15 to DN50), mass, and dimensions of individual components, while the basic materials, construction design, and functional properties remain the same.
2201 Series (nickel-plated brass body)
• 1 2201 41 – 1 2201 56: Ball valve with extended T-handle, PN25 – For heating, cooling, and water systems
• 1 2201 61 – 1 2201 76: Ball valve with extended T-handle and thermometer, PN 25 – For heating, cooling, and water systems with temperature monitoring .
2206 Series (dezincification-resistant brass body)
• 1 2206 41 – 1 2206 56: Ball valve with extended T-handle, PN25 – For heating, cooling, and potable water systems
• 1 2206 61 – 1 2206 76: Ball valve with extended T-handle and thermometer, PN25, For heating, cooling, and potable water systems with temperature monitoring
The 2201 series uses nickel-plated forged brass, while the 2206 series uses DZR brass for enhanced corrosion resistance in potable water applications.
Common technical characteristics of all products within the group:
- Full bore
- Nominal pressure: PN 25 (25 bar)
- Operating temperature range: –30 °C to +150 °C (water +0.5 °C to +110 °C, no steam)
- Media: water, fuel oil, lubricating oils, air, and other non-aggressive media
- Materials: brass (main body), reinforced plastic (handle), PTFE (seals), EPDM/NBR (O-rings), stainless steel (some components)
The main differences between the individual valves in the group are the percentage of brass by weight (approximately 86% for DN15 to 95% for DN50) and minor differences in the amounts of plastic and PTFE seals. These differences result in differences in environmental impacts of ≤10% for most primary input streams (brass, plastic, PTFE). The valve with the highest impact for most indicators is the DN50 model; therefore, it was selected as the worst representative for the statement of results. |
