Non rotating-stem Needle Valves ND/NDH Series
ND and NDH Series Non-Rotating Stem Needle Valves feature a one-piece forged body and a compact design, supporting pressures up to 5,000 psig. A non-rotating stem extends service life, while a soft stem tip enhances sealing performance. These valves feature an O-ring seal for low operating torque and a specially designed handle that prevents contamination. Available in straight and angle flow patterns, with various connection types and sizes.

Features
◎ One-piece forged body
◎ Straight and angle pattern
◎ Compact design
◎ Non-rotating stem
◎ Specially designed handle to stop contamination from entering into the valve
◎ Every valve leak tested with Nitrogen or compressed air at the maximum allowable working pressure
◎ Working pressure up to:
ND Series : Stainless steel: 3000 psig (207 bar)
Brass: 3000 psig (207 bar)
NDH Series : Stainless steel: 5000 psig(345 bar)
◎ 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)
Features
Nonrotating-stem Needle Valves
◎ Working temperature with stem tip :
PCTFE stem tip : -20°F to 200°F (-28°C to 93°C)
PEEK stem tip : -20°F to 400°F (-28°C to 204°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.
