Rising Plug Valves : NR Series NRG (with gauge port) Series
NR and NRG Series Rising Plug Valves feature a cold-drawn square bar body, supporting pressures up to 6,000 psig (414 bar). A non-rotating stem extends seat life. The straight-through, roddable flow path maximizes flow while minimizing pressure drop. Stem thread lubricant is isolated from system media, while a tapered seat enhances sealing. The seat and stem tip are replaceable, and a PTFE ring in the gland protects the stem thread from contamination. Available in various connection types, sizes, and handle colors.

◎ Working temperature with O-ring :
Fluorocarbon Rubber (FKM) : -20°F to 400°F (-28°C to 204°C)
Nitrile Butadiene Rubber (NBR) : -20°F to 212°F (-28°C to 100°C)
Ethylene Propylene Diene Rubber (EPDM): -20°F to 300°F (-28°C to 148°C)
When the connection type of valves is FITOK double ferrule tube fitting,the working pressures of the valves are related to the wall thickness of tubing applied. For specific working pressure of the valves.
