This 2-way DN 25 flanged ball valve is made of cast steel with Teflon (PTFE) sealings. Standardized length of 125 mm conforming to DIN 3202-F4 (EN 558-1 Row 14). The valve is suitable for water, oil, air and fuel up to a maximum pressure of 40 bar (580 psi) and vacuum (max. -0.9 bar or -13 psi). This valve is DVGW certified for gas (MOP 40 bar) in accordance with EN 14141. The valve can be equipped with an actuator using the ISO 5211 F05 flange, but it requires a separate adapter and mounting bracket, which are not provided. The valve operates within a temperature range from -20 to 180 °C (-4 to 356 °F).

This 2-way DN 25 flanged ball valve is made of cast steel with Teflon (PTFE) sealings. Standardized length of 125 mm conforming to DIN 3202-F4 (EN 558-1 Row 14). The valve is suitable for water, oil, air and fuel up to a maximum pressure of 40 bar (580 psi) and vacuum (max. -0.9 bar or -13 psi). This valve is DVGW certified for gas (MOP 40 bar) in accordance with EN 14141. The valve can be equipped with an actuator using the ISO 5211 F05 flange, but it requires a separate adapter and mounting bracket, which are not provided. The valve operates within a temperature range from -20 to 180 °C (-4 to 356 °F). An actuator can be mounted using a mounting flange according to ISO 5211 when it is used in conjunction with a special bracket and shaft adapter.

Pros:

  • Standardized installation length of 125 mm according to DIN 3202-F4
  • Unobstructed flow path thanks to the full bore design
  • Suitable for vacuum
  • Easy installation and maintenance thanks to the standardized DN 25/PN 40 flange

Cons:

  • To disassemble the valve for inspection and cleaning it has to be completely removed from the pipe
