Dome pressure regulator 737LE-HD/S CO₂

Product information "Dome pressure regulator 737LE-HD/S CO₂"

WITT 737LE-HD/S high-performance, high-pressure dome pressure regulator set, specifically designed for carbon dioxide (CO₂), 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, withdrawal rates and temperatures. The medium-controlled system operates completely autonomously and, thanks to user-friendly, standardised connections, is easy 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
  • Specially designed and optimised for safe use with carbon dioxide (CO₂)
  • High pressure stability even with fluctuating inlet pressures, withdrawal rates and temperatures
  • Suitable for high pressure: for inlet pressures up to 100 bar
  • Outlet pressure range: 0.5 – 26 bar
  • 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: feedback-capable; no escape of the control gas into the atmosphere
  • Material: brass, connections: inlet G 3/4" female (with filter) / outlet G 1" female, Kv value 1.65
  • 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 in any orientation, indoors or outdoors
