Needle Valve – DBB

Features

Standard non-rotating free swivel stem tip.
Upper stem thread lubricant is isolated from system fluid.
Non-rotating lower stem avoid galling damage to the seat and tip, as well as reduces the total friction area between the packing and lower stem.
Back seating design provides secondary stem sealing and prevents stem blowout.
Adjustable gland flange allows packing adjustment.
Stem packing below thread design prevent media contamination and thread lubrication washout.
Pressure rating upto 10,000 psig (690 Bar)
Temperature rating are as follows:
PTFE: -65°F to 450°F (-54°C to 232°C)
Graphite: -65°F to 1200°F (-54°C to 649°C)
