Multiple V-Ring Packing

Preferred by Maintenance Technicians

MULTIPLE V-RING PACKING

DeZURIK’s adjustable V-ring packing has four separate rings that work as a system. Each ring is capable of sealing the valve stem. Multiple rings provide extra protection from stem leakage.

If stem leakage should occur, our eccentric plug valves have an open space between the valve cover and the actuator to prevent leakage from entering the actuator.

This open space allows for inspection, adjustment and even packing replacement without removing the actuator. Packing replacement can be done while the valve is in service, which is not possible with nonadjustable packing designs.

Optional PTFE V-ring type packing is available for high temperature or corrosive applications.

How to Specify

Adjustable packing shall be Acrylonitrile-Butadiene (NBR) multiple V-ring type, with a packing gland follower. Packing gland access shall permit inspection, adjustment or complete replacement of packing without disturbing any part of the valve or actuator assembly, except the gland follower. Non-adjustable packing or packing requiring actuator removal to replace the packing is not acceptable.
