"V"

V-Packing - Also known as Vee Packing, Vee Sets, Chevron Packing, Parachute Packing. A multiple ring set of packings whose center rings or sealing rings are V-shaped to form sealing lips. The V-rings stack on top of each other and have a male and female adaptor on each end to make the set flat. This packing type is adjustable.

Valve Discs - A PTFE or Teflon disc used on a valve as a seat to provide positive sealing whn shut off.

Value Engineering (Value Analy- sis) - A planned, clean sheet approach to problem solving, focusing on specific product design and process characteristics. Where value analysis is employed to improve value after production has begun, value engineering is employed to maximize value prior to expend- itures of facilities and tooling money.

Valve Packing - Braided packing used in the stuffing box of a valve stem to make a positive seal.

Valve Seats - A PTFE or Teflon disc or ring used on a valve as a seat to provide positive sealing whn shut off.

Valve Stem Packing - Braided packing used in the stuffing box of a valve stem to make a positive seal.

Vee Packing - Also called V-Packing, Vee packing, Chevron Packing, Parachute packing or v-set packing. A complete vee packing set contains multiple "V" shaped sealing rings stacked and nested together with a male adapter on one end and a female adapter on the other end.

Vibration Mounts - A rubber piece used to eliminate vibration between to components.

Viscosity - The resistance of a material to flow under stress.

Voice of the Customer - Customer feedback both positive and negative including likes, dislikes, problems and suggestions.

Voice of the Process - Statistical data that is feedback to the people in the process to make decisions about the process stability and/or capability as a tool for continual improvement.

Voids - The absence of material or an area devoid of materials where not intended.

V-Packings - Also called V-Packing, Vee packing, Chevron Packing, Parachute packing or v-set packing. A complete vee packing set contains multiple "V" shaped sealing rings stacked and nested together with a male adapter on one end and a female adapter on the other end.

V-Rings - Also called V-Packing, Vee packing, Chevron Packing, Parachute packing or v-set packing. A complete vee packing set contains multiple "V" shaped sealing rings stacked and nested together with a male adapter on one end and a female adapter on the other end.

Vulcanizate - Rubber in its cured or vulcanized state.

Vulcanizating Agent - Any material which can produce in rubber the change in physical properties known as vulcanization, such as sulfur, polysulfides, organic polynitro derivatives, peroxides arid quinone dioximes.

Vulcanization - An irreversible process during which a rubber compound through a change in its chemical structure (for example, cross-linking) becomes less plastic and more resistant to swelling by organic liquids and elastic properties are conferred, improved, or extend- ed over a greater range of temper- ature.
