Valve Manifold - 910.25

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
One-way valves
With model 910.25 valve manifolds single-sided overpressure loading during start-up and operation phases can be avoided by means of a pressure compensation of the j and i side. In addition, zero adjustments are possible during the running process. 

Three-way valves 
Three-way valves include additional valves, which enable a shut-off of the process lines during operation. This simplifies the dismounting, testing and shutdown of the measuring instrument, and it also protects from impermissible overpressure loading. Furthermore, the measurement of Static-Pressure is possible (after dismounting the measuring instrument). 

Four and five-way valves 
Furthermore, these valve manifolds, with integrated shutoff, purge and vent valves, enable the pressure gauge to be vented on one or both sides and the supply line to be purged.
Features
  • One-way, three-way, four-way and five-way valves. 
  • Robust brass or stainless steel versions. 
  • Valves for PN 100 and 400 with double-sided cone seals. 
  • Wide variety of process connections. 
  • Nominal pressures to 40, 100 or 400 bar.
