NRS Resilient Seat Gate Valve
The BLAZE™ NRS Resilient Seated Gate Valve is designed for reliable shut-off in potable water systems, HVAC networks, mechanical services, and industrial pipelines. Featuring a non-rising stem (NRS) design, it is ideal for installations with limited vertical space while still ensuring efficient operation and long-term durability.
Constructed with a ductile iron body and fully coated in Fusion Bonded Epoxy (FBE) in RAL 5015 blue, the valve offers excellent corrosion resistance and hygiene for potable water use. The resilient seated wedge, fully encapsulated in EPDM rubber, provides bubble-tight sealing with minimal operating torque.
