PRODUCTS:

Depending upon the service conditions, most all Apollo® Valves could be used in Abrasive and Slurry service. However, within
this Guide we are covering the difficult to handle services, so the products we would typically recommend are limited.

1. Apollo® Concentric Butterfly WD 141 & LD 141 Series. Never overlook these valves in Abrasive/Slurry services. The resilient
Seat Liner is excellent for some Abrasive/Slurry services. However, the valve does not provide for drain and/or purge ports,
and the allowable working pressure/temperature rating of the valve may preclude using the BFV. The Cast Iron Body material,
and limited Disc/Stem materials, can restrict applications as well.

2. Apollo® Flanged products – 87A and 88A Series. With the proper tools (pipe spreader) this valve could be considered in-line
repairable. However, most flanged end ball valves are removed from the line to be repaired. The Bodies do have a cast boss
that can be drilled and tapped for a drain and/or purge port. Valves are available with Full Ports. Available Seat materials
limit this valve style in some applications. These are available with UHMWPE and PEEK seat materials which are abrasion
resistant. We also have the ability to offer surface hardened balls for added wear resistance.

3. Apollo® Three-Piece products – 83A/B and 86A/B Series. Since this valve is totally repairable in-line, there are more application
possibilities for the Apollo Three-Piece products. The valve design includes three bosses that can be drilled and tapped
for use as drain/purge ports. Valves are only furnished as Full Port valves. Cavity fillers were also designed for this valve …
cavity fillers will minimize the amount of solids build-up in the Body cavity … the negative here is the cavity fillers naturally
increase operating torque. Like with the flanged end valves, available Seat materials limit this valve design in some
applications. Alternate Seat materials available include UHMWPE and PEEK which are abrasion resistant. We also have the
ability to offer surface hardened balls for added wear resistance.

4. Apollo® Top Entry Series - This is the “work-horse” of the Apollo Industrial offering, and it really proves this when applying
the product in Abrasive/Slurry services. The valve design provides for in-line repair and easy clean out. Drain/Purge ports
can be provided, drilled and tapped, for keeping the valve center cavity clear of solids (slurry materials). This valve design
can accommodate a vast selection of seat/trim materials. Abrasion resistant seat materials available include UHMWPE and
PEEK. We also have the ability to offer surface hardened balls for added wear resistance. For the really severe applications we
can provide top entry valves with solid ceramic ball and seats. These valves are available in regular port as well as full port,
but the design is such that the flow path is not completely straight and does not allow line pigging.

GENERAL NOTE: It is important with slurry applications to consider not only the chemical compatibility (corrosion resistance), but to also consider the
percentage of solids, what the solids are (if they are abrasive) and the size of the particles. Remember that as most ball valves operate, it allows the flowing
media to get into the body cavity of the valve. This is important knowledge as it helps determine if hardened materials need to be utilized for erosion
resistance or if the particulate is likely to pack up in the cavity, increasing torque, thus making the valve difficult or impossible to operate.
