Ron-Vik offers four sizes of bowls, one for each of the product series. The top-bowl connection is a buttress thread to prevent cross threading. For application flexibility, the bowls are offered in 20% glass filled polypropylene, 66 nylon and clear nylon. The chart below outlines the major differences between these materials. Chemical compatibility for your individual use should also be confirmed.

Ron-Vik offers custom elements down to 5 microns. They can have molded or hemmed edges. We also offer caged synthetic mesh elements. Please contact us for more information and minimums.

Ron-Vik has over 50 years of experience developing and manufacturing custom product solutions for our customer's straining and filtration needs. We employ an experienced staff of engineers and toolmakers to assist in the design of, and frequently build the tooling necessary to manufacture, custom products combining wire and synthetic mesh with thermo-plastic and plastisol. We have a wide variety of manufacturing processes at our facility, including horizontal and vertical injection molding, pot molding, spin welding, seam welding, induction welding, stamping, slitting and shearing. This allows us to design and manufacture the most cost effective product solution and to insure quality in every step of the process. Many of our custom product solutions are molded from mesh and plastic, utilizing our insert injection molding or pot molding capabilities. These processes allow for flexibility in design and material selection. They also offer significant advantages in cost and ease of manufacture over other potential solutions. Insert Injection Molding Ron-Vik has years of experience in manufacturing insert injection molded filters for our proprietary in line strainers. We have expanded our insert injection molding capabilities to allow us to design and manufacture a wide range of insert molded custom products. Most of these products combine cylinders or flat blanks with thermoplastics or thermoplastic elastomers (TPE's)(as shown in the picture). These products offer significant advantages over metal on mesh, welded or soldered designs. These components are made by taking a prefabricated mesh form and putting it into an injection mold. The mold closes around the mesh and plastic is injected to create a gasket andor a support cage. Mesh sizes range from 1 micron openings up to 2000 micron openings. Our experienced engineering staff will assist you in the design of a component that will achieve your desired results. Common Materials Support cagegasket materials • Nylon: most varieties including filled • Polypropylene: homopolymers and copolymers including filled • Polyethylene: high density and low density • Polyester: most varieties including filled • Acetal: homopolymers and copolymers including filled • Santoprene® in most durometers • Geolast® in most durometers • Others: contact us if you need a material that is not listed Filter Materials • Stainless steel: most alloys, 2 to 2000 micron • Other metals: most alloys including epoxy and Teflon coated • Nylon from 1 to 2000 micron • Polyester from 1 to 2000 micron • Polypropylene from 75 to 2000 micron Cylinders and Cones Cylinders and cones are ideal for applications requiring a maximum amount of surface area. Parts can be designed with the flow going from either insideout or outsidein. Basic design considerations should include: • Maintain as consistent cagegasket cross section as possible • Keep above cross sections over .050" wherever possible • Incorporate at least one, preferably two longitudinal ribs to cover seams in mesh. • Add circumferential ribs as necessary for strength. • To allow for easy core pulls, minimize undercuts on ID of part. • Male threads are best. Use female threads only if absolutely necessary. • Diameters between .250" to 4" and lengths from .500" to 8" are best. Blanks Both flat and formed blanks are easily insert injection molded. These are ideal designs where space is at a premium. Basic design considerations should include: • Maintain as consistent cagegasket cross section as possible. • Keep above cross sections over .050" wherever possible. • For domed parts allow for a flat shut-off area on the ID of the cagegasket. • To allow for easy core pulls, minimize undercuts on ID of part. • Male threads are best. Use female threads only if absolutely necessary. • Keep part size under 18" square Pot Molding For over 50 years Ron-Vik has been the leader in PVC pot molded filters and strainers. Our pot molding capability combines the efficient filtration of wire mesh with economical PVC flanges andor gaskets to provide a wide array of filtration and straining products. We can mold cylinders and formed blanks with either rigid or flexible gasketsflanges. PVC is available in a wide variety of colors and durometers range from 40 Shore A to 60 Shore D. Materials PVC: Black vinyl plastisol (PVC) in a 70 durometer shore A is used to manufacture bases that are flexible yet durable and economical. Note: If the install ation puts this base in direct contact with any styrene based components please advise your customer service representative as our standard material is not recommended. Mesh Materials Stainless Steel type 304: The basic stainless all oy (18% chrome, 8% nickel) and the most extensively used to weave wire cloth. It has excellent corrosion resistance whi ch is satisfactory for most applications. Where no type is specified, it is assumed that type 304 is acceptable. Stainless Steel type 316: The same characteristics as type 304 with an additional 2% molybdenum to provide increased corrosion resistance to salts and acids. In additional it has increased strength at high temperatures. Monel® alloy 400: A high nickel copper alloy which is one of the most widely used alloys for corrosion resistance. It has the strength of a mild steel and will not corrode in a great many solutions found in industrial applications. Cylinders and Cones Pot molded cylinders and cones are ideal for applications where a maximum amount of surface area is required. Gaskets and flanges can be either rigid or flexible and the two ends of the parts do not have to be the same durometer. Basic design considerations should include: • Maintain PVC thicknesses of at least .080" • Minimize undercuts on ID and OD of part. • Locate screen to ID of flangegasket wherever possible. • Maintain a flat PVC profile on the top of the flangegasket surface when possible • Allow for some wicking of PVC into the mesh, especially fine mesh. • Diameters between .250" and 12" are best. • Part length should be kept under 18" • Advise your Ron-Vik engineer if the part will be in contact with any styrene based plastics. Stampings Pot molded stampings are space efficient filters and strainers. They can be anything between round and square, with any multitude of screen profiles. Basic design considerations should include: • Maintain PVC thicknesses of at least .080" • Minimize undercuts on ID and OD of part. • Locate screen to ID or OD of flangegasket wherever possible. • Screen must exit the flangegasket from the top. It cannot bisect the PVC. • Screen should protrude at least .250" above the PVC. • Maintain a flat PVC profile on the top of the flangegasket surface when possible • Allow for some wicking of PVC into the mesh, especially fine mesh • Part sizes under 12" square are best. • Advise your Ron-Vik engineer if the part will be in contact with any styrene based plastics.

In-line strainer tops are available in either black 20% glass filled polypropylene or white 66 nylon materials. Ron-Vik offers a variety of port types and sizes. Male NPT - available in 18", 14", 38" and 12" Female NPT - available in 18", 14", 38", 12", 34", 1", 1 14" and 1 12" Hosebarb - available in 14", 38" Quick connect fitting - available for 14" and 38" OD tubing Existing tooling available for reversed arrow direction, and BSP threads.

• Wire mesh screen is the most common element utilized in the in-line strainer assemblies. Standard caged stainless steel mesh sizes are 20, 50, 80 and 50x250. • Polyethylene filter (PE) are offered in the low profile, regular and large series. The filter is a depth type filter making it non-cleanable.
