Rising Plug Valves
NR Series
NRG (with gauge port) Series
Features
◎ Cold drawn square bar as body material
◎ Nonrotating stem for longer seat life
◎ Roddable, straight through flow path for maximum flow with minimum pressure drop
◎ Stem thread lubricant isolated from system media
◎ Replaceable seat and stem tip design
◎ Stem thread protected from outside contamination by PTFE ring in the gland
◎ Panel mounting available
◎ Handles of different colors available
◎ Every valve leak tested with Nitrogen or compressed air at the maximum allowable working pressure
◎ Working pressure up to:
Stainless steel : 6000 psig (414 bar)
Alloy : 400: 5000 psig (345 bar)
◎ Working temperature with seat:
Acetal : -20°F to 250°F (-28°C to 121°C)
PEEK : -20°F to 450°F (-28°C to 232°C)
◎ 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.
