Fisherr Z500 Severe Service Ball Valves

This bulletin covers Fisher NPS 1/2  36 Z500 Severe

Service Ball Valves. The Z500 severe service ball valve

line is a simplistic two-piece floating ball design with

integral metal seat meant to provide tight metal

seating shutoff in high temperature, high pressure,

and erosive applications across all industries. The mate

lapped ball and seat constructions help ensure sealing

and the high-velocity oxyfuel coatings (HVOF) provide

excellent corrosion resistance and help eliminate the

problems associated with severe service conditions.

Z500 valves are available with a variety of end

connections from ASME CL150 through CL4500.

All Z500 valves are designed and manufactured to be

used in severe service applications. They are highly

engineered to help enhance safety in potentially

dangerous operating parameters and reduce valve

maintenance costs.

Features

n Machined Stops -- Integral 90 degree lockplate

design prevents over-rotation and maintains critical

alignment on lever-operated valves.

n Side Mounted Bracket -- Helps prevent stem and

packing box side load and bolt stress loads by

attaching to the side of the valve body.

n Live-Loaded Packing - Packing design utilizes

live-loaded spring washers for easy adjustment.

Compact stuffing box and liveloaded Belleville

springs ensure packing is continuously energized

and protects against stem side loading and

temperature fluctuations.

n Stem Adapter - Lever-operated valves have a

contactproof stem adapter designed to prevent

the stem from being knocked into the ball, causing

misalignment and possible leakage.

n BlowOut Proof Stem - Rugged, onepiece,

machined, surface-hardened and polished stem is

designed to be blowout proof. There are no pins to

rely on, which helps increase safety and reliability.

n Integral Metal Seat - Preferred sealing seat is

machined into the end adapter, coated, and mate

lapped with the ball. Design eliminates a potential

leak path and helps the valve withstand high

pressures, temperatures and severe service

conditions.

n Metal Body Gasket - Specially engineered,

selfenergizing gasket helps ensure that there is no

leakage during thermal transients.

n High-Velocity Oxyfuel Coatings (HVOF) - Forms a

very hard and dense coating on the base metal of

the ball forming a strong mechanical bond.

Typically these coatings are chromium or tungsten

carbide. These coatings provide exceptional wear,

corrosion, and erosion resistance.
