NF&NFH Forged Body Needle Valves

Description:

One-piece forged body
Two-piece stem design: Upper stem threads cold
rolled and lower stem hardened for high strength and
smooth operation
Upper stem thread lubricant 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
Panel mounting available
Steady and durable fastening of the handle by double
lock-pins
Handles of different colors available
