Bermad - Model 120DC - 3 Way - Double Chamber Pressure Reducing Valve

The Bermad Model IR-120-DC-3W-XZ Pressure Reducing Valve is a double chambered, hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop.

• Line pressure driven, Hydraulically Controlled
• Protects downstream systems
• Opens fully upon line pressure dropֺ Double chamber
• Full powered opening and closing
• Decreased pressure loss
• Low throttling noise
• Non-slam closing characteristic
• Protected diaphragm
• Engineered Plastic Valve with Industrial Grade Designֺ hYflow ‘Y’ Valve Body with “Look Through” Design
• Ultra-high flow capacity - Low pressure lossֺ User-Friendly Design
• Simple in-line inspection and service

• Pressure Reducing Stationsֺ
• Systems Subject to Varying Supply Pressureֺ
• Energy Saving Irrigation Systems
