nnnn

strength and Integrity to Instrument needle valves. Budenberg

nnnn

have Incorporated a dynamic multi-ring gland system In the

nnnn

needle valve, which when combined with the anti blow-out

nnnn

back seating stem, guarantees resistance to all operating

nnnn

processes and pressures.

nnnn

Low operating torques and high cycle life feature strongly In this

nnnn

unique Budenberg design, giving a " Low Cost of Ownership".

nnnn

Key Benefits are:

nnnn

• Guaranteed Sealing with the minimum effort

nnnn

• Over designed high strength adaptor threads combine with

nnnn

soft' parent metal bottom seal to give closure thread protection

nnnn

and ensures environmental safety

nnnn

• Gland and stem leakage is a thing of the past due to the

nnnn

dynamic multi-ring gland system, combined with the anti

nnnn

blow-out back seating system

nnnn

• Swaged self centering non-rotating Duplex stem ensures

nnnn

point positive seat closure under all conditions
