rdpDIRECT PRESSURE REGULATOR (RDP) pdf icon

The direct pressure regulators are automation devices, with no auxiliary energy that control the upstream and downstream working fluid pressure.

Technical characteristics

Nominal diameters: 10 … 150mm
Nominal pressure on case of cock: 16; 25; 40 bar
Maximum working fluid temperature: 325 °C
Working fluid: water; air; steam; gases; oil products, refrigerant agents
Adjusted pressure: 0.2 … 10 bar
Maximum working fluid temperature:
• 80°C for regulator without separation vessels;
• 225°C for regulator with separation vessels;
• 300°C for regulator with servomotor with bellows
