PRODUCT INFORMATION

Bermad 3HC – Pressure Sustaining Pilot

This is a direct acting valve, actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. When used in a pressure relief/sustaining circuit, the pilot modulates open as upstream pressure rises above set point.

APPLICATION:

• Pressure Relief/Sustaining Valves sizes 16-32”

(Standard model #3HC)

• Differential Pressure Sustaining 16-32”

(Modified to differential sensing #3HC-DR)

• Surge Anticipating Valve sizes 6-14” as high pressure pilot

(Modified to external pressure sensing #3HC-R)

FEATURES & BENEFITS

• Internal or external pressure sensing
• Differential pressure sensing
• Direct Pressure gauge installation
• Non-tamper safety cap
