Product information "Dome pressure regulator 737LE-HD/S"
WITT high-performance, high-pressure dome pressure regulator set 737LE-HD/S for pipeline 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 in any orientation, indoors or outdoors.
Key features:
- Ready-to-install complete solution: assembled and tested with an integrated control pressure regulator and pressure gauges for inlet and outlet pressure
- High pressure stability even with fluctuating inlet pressures, withdrawal rates and temperatures
- Suitable for high pressure: for inlet pressures up to a maximum of 300 bar (up to 200 bar for O₂)
- 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-controlled, 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 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
