Technical purpose Ball valves are used as closing, filling - draining fitting in industry and construction. Ball valves are used wherever the medium flow has to be reliably closed. Operating pressure varies according to the size and is given in the data sheet.

Common characteristics for most Herz ball valves (series 1 22xx, 1 21xx, 1 24xx, etc.):
Body: Forged brass (often nickel-plated or DZR/dezincification-resistant)
Ball: Full bore, Seals: PTFE (ball & spindle/stem) or with EPDM.
Connections: Female thread ISO 228, some with union nut or male thread
Temperature range: -30 °C to +150 °C (water ≥0.5 °C, max. 110 °C short-term, no steam)
Medium: Water, chilled water, heating, non-aggressive media.
The main differences between the individual valves in the group are the percentage of brass by weight (approximately 81% for DN8 to 93% for DN50) and minor differences in the amounts of plastic and PTFE seals. These differences result in differences in environmental impacts of ≤20% for most primary input streams (brass, plastic, PTFE). The valve with the highest impact for most indicators is the DN8 model; therefore, it was selected as the worst representative for the statement of results. |
