NU Series: Working pressure up to 6000 psig
NUH Series: Working pressure up to 10000 psig

◎ One-piece forged body
◎ Two-piece stem design: Upper stem threads cold rolled and lower stem hardened for high strength and smooth operation
◎ Accidental valve disassembly disabled by union bonnet construction
◎ Upper stem thread lubricant isolated from system media
◎ Linear instead of rotary movement of the rising, non-rotating stem minimizes packing abrasion and reduces the friction between the seat and the tip
◎ Safety back seating seal in fully open position
◎ Panel mounting available
◎ Steady and durable fastening of the handle by double lock-pins◎ Handles of different colors available
◎ Every valve leak tested with Nitrogen or compressed air (NU Series)at the maximum allowable working pressure or with water (NUH Series)at 1.1 times the maximum permissible pressure
◎ Working pressure up to:

• NU Series Stainless steel: 6000 psig (414 bar)
• Alloy C-276: 6000 psig (414 bar)
• Alloy 400: 5000 psig (345 bar)
• Titanium: 3500 psig (241 bar)

NUH Series-stainless steel: 10000 psig (690 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°℃ to 649°C)
