Outside Screw and Yoke OS&Y Needle Valves: NY Series
NY Series : Working pressure up to 6000 psig
Features OS&Y Needle Valves
◎ Cold drawn bar as body
◎ Standard seat diameter 0.16″ (4mm). Cv: 0.35 standard
◎ Hardened stem threads prevent galling
◎ Stem threads completely isolated from system media
◎ Linear instead of rotary motion of the rising, non-rotating stem minimizes packing abrasion and reduces the friction between the seat and the tip
◎ Externally adjustable gland, independent of spindle thread
◎ Steady and durable fastening of the handle by double lock-pins
◎ Bottom mounting available
◎ Every valve leak tested with Nitrogen or compressed air at maximum allowable working pressure
◎ Working pressure up to :
Stainless steel: 6000 psig (414 bar)
Alloy C-276: 6000 psig (414 bar)
Alloy 400: 5000 psig (345 bar)
◎ Working temperature:
PTFE: -65°F to 450°F(-54°C to 232°C)
PEEK: -65°F to 500°F (-54°C to 260°C)
Graphite: -65°F to 1200°F (-54°C to 649°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.
