Air pressure regulator P1098

for gasdiaphragmsteel

Product Description
The BelGAS P1098 pressure reducing regulator is a pilot-operated regulator designed for large-volume gas control with outlet pressures from inches of water column up to 75 PSIG depending on pilot selection. It features a two-path pilot system and a large-area actuator diaphragm for fast, accurate response. The pilot amplifies control to the main valve; a sharp-edged orifice and soft seat deliver bubble-tight shutoff.

Key Features

• Multiple pilot options covering low to high outlet pressures
• Main valve inlet pressure capability varies by pilot (up to 600 PSIG)
• Loading pressure bleeds downstream (no atmospheric relief)
• Pilot amplifies main valve for precise control
• Connection options: NPT or flanged (150 RF, 300 RF)
• Rebuild kits and spare parts available
