Overview
The ultimate in on/off product cycle life, our "Life Series" needle valves comprise a Virgin PTFE tipped needle for exceptionally low torque, long life on/off operation. In applications where the end user needs to operate a needle valve from open to closed position on a high frequency basis, the "Life Series" provides all the inherent benefits of a Needle Valve while providing a longer service life compared to rigid hard seated needle valves where galling can occur from high frequency on/off operation. 
 
Features:

PTFE On/Off seal is easily replaced in the field, no tools required
Exceptional Low Torque on/off operation
Needle finish, SPI/SPE No. 1. Bubble tight, low torque shutoff long term performance.
All injection molded, rugged design and construction
24 Pitch metering thread. 20% Finer metering control. Excellent Linearity of Flow.
Needle Stem is PTFE sealed for excellent chemical resistance & high purity.
Integrally designed panel mounting, no fasteners required, mounts to panel thicknesses from 1/16" to 1/2".
No elastomers (O-Rings), metals or lubricants, no corrosion, no contamination.
