Dome pressure regulator 757LE/S-ES

Product information "Dome pressure regulator 757LE/S-ES"

WITT high-performance dome pressure regulator set 757LE/S-ES in stainless steel, for pipework installation or as a main pressure regulator in accordance with DIN EN ISO 7291. This ready-to-install complete solution guarantees maximum pressure stability even at extremely high flow rates, fluctuating inlet pressures and temperatures. The self-acting system operates completely autonomously and, thanks to user-friendly, standardised connections, is simple to install indoors or outdoors, regardless of orientation.

Highlights:

  • Ready-to-install complete solution: assembled and tested with an integrated control pressure regulator and pressure gauges for inlet and outlet pressure
  • Housing and components made from high-quality stainless steel (1.4404 / 316L) – specially designed for corrosive, aggressive and toxic gases and demanding environmental conditions
  • High pressure stability even with fluctuating inlet pressures, extremely high flow rates and temperatures
  • Maximum flow rate: large-bore valve with G 2" female thread (flange) connections and a very high Kv value of 15.0
  • Pilot Control Tube (PCT) ensures an extremely accurate outlet pressure (working pressure)
  • Balanced Seat Design (BSD) ensures precision, high reliability and long maintenance intervals
  • Self-acting – enables autonomous operation without a separate gas supply
  • Closed system: self-regulating, no escape of control gas into the atmosphere
  • Food-safe (HACCP / EC 1935/2004 / LFGB) and designed/cleaned for O₂ applications in accordance with EIGA / CGA
  • Wide range of applications – suitable for numerous technical and corrosive gases
  • Easy to use: pressure adjustment possible at any time whilst the system is in operation via a removable spindle
  • Reduces planning effort thanks to installation in any orientation, indoors or outdoors
