NEEDLE VALVES
 |
The needle valve is designed to provide bubble-tight shutoff of liquids or
gases and is used primarily to closely regulate fine flow. However, it may be
used as a throttling device on lines to a pressure gauge where rapid and
excessively pulsating pressures would tend to affect gauge performance or
mechanism. |
• Metal to metal hard seat
design for a bubble tight seal.
• 10,000 psi pressure rating (@ 200°F maximum).
• Blow out proof stem that provides a secondary stem seal in the full open
position.
• Stem packing below the threads prevents thread galling and corrosion.
• Viton O-ring and Teflon back-up ring stem seals.
• All 316SS Stems (even in steel valves) for longer life.
• Stem and bonnet threads are rolled for greater strength and smoother
operation.
• Stem and bonnet sealing surfaces are burnished to a 16 RMS mirror
finish.

• One-piece bonnet with a metal to metal seal to the valve body below the
bonnet threads.
