Dome pressure regulator 737LE-HD/S-ES

Product information "Dome pressure regulator 737LE-HD/S-ES"

WITT high-performance, high-pressure dome pressure regulator set 737LE-HD/S-ES in stainless steel, for in-line installation or as a main pressure regulator in accordance with DIN EN ISO 7291. This ready-to-install complete solution for high inlet and outlet pressures guarantees maximum pressure stability even with fluctuating inlet pressures, flow rates and temperatures. The medium-controlled 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 aggressive, corrosive, toxic and flammable gases (not suitable for O₂)
  • High pressure stability even with fluctuating inlet pressures, flow rates and temperatures
  • Suitable for high pressure: for inlet pressures up to a maximum of 300 bar
  • Extended temperature range from –30 °C to +50 °C
  • 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-contained – enables autonomous operation without a separate gas supply
  • Closed system: reversible, no escape of control gas into the atmosphere
  • Food-safe (HACCP / EC 1935/2004 / LFGB) for use with food-grade 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 at any orientation, indoors or outdoors
