Features & Benefits
Replaces Traditional Root Valve Assembly
Single monoflange body replaces separate root valve, nipple, tee, and bleed valve, reducing leak paths and weight by 70%.
Direct Flange Mounting
Bolts directly between process nozzle flange and instrument or transmitter flange, eliminating threaded connections and adapters.
Compact Design
Reduced face-to-face dimension allows installation in tight nozzle clearances where traditional valve assemblies are too long.
Non-Rotating Needle Tips
Both block and bleed valves use hardened non-rotating tips for bubble-tight shutoff and long cycle life.
Blow-Out Proof Stems
Retention collars on both valve stems prevent accidental ejection under pressure during maintenance.
