Model 3100 Series -Normally Open Master Valve

• Low seat design with two-piece internal assembly decreases pressure loss and improves flow when compared to valves with high seat design, and helps protect diaphragm from harmful debris. Normally Open design allows for constant system pressurization and on-demand access to manual irrigation and quick coupler use
• Self-cleaning inlet orifice with metering rod allows only “clean water” to enter upper diaphragm chamber offering consistent, trouble-free operation
• All EPDM rubber parts outlast commonly used Buna-N parts when exposed to reclaimed water
