About Gate valves

A gate valve closes the line with a wedge that moves across the flow and leaves almost the full bore open in the open position. The group covers threaded connections from G 3/8 to G 3 and nominal sizes from DN 10 to 70 mm. Permitted operating pressure is 14 to 16 bar depending on the body material.

What matters when choosing

• Thread G 3/8 to G 3 and DN 10 to 70 mm follow the existing pipework, the socket version screws in directly.
• Body in brass or 1.4401 / 1.4408 stainless steel: stainless is meant for aggressive media and outdoor installation, brass covers compressed air and water lines inside the building.
• Max. operating pressure 14 to 16 bar: the brass valves are rated 16 bar, the stainless ones 14 bar.
• Flow rate 67 to 869 l/min: the required volume decides which nominal size is actually sufficient.
• Version with or without spindle stroke: without spindle stroke the installed height stays the same while opening, which matters in shafts and crowded manifolds.

Typical applications

• Shut-off points in compressed air ring mains and plant supply lines
• Maintenance isolation ahead of filters, pumps and water meters
• Cooling and heating circuits in building services
• Water lines in plant and vessel construction
• Process lines where the stainless steel version is specified

Bodies are made of brass or 1.4401 / 1.4408 stainless steel, and part of the range uses PTFE sealing. Operating temperatures from -10 °C to 120 °C are released, manufacturing takes place in Taiwan and China.
