Valve Boxes & Risers.
For utilities, contractors and distributors who need valve boxes that match the local standard.
✓ Screw, slip and three-piece boxes ✓ Light castings price sheets
✓ Heavy-duty versions
Made to the local standard.
Valve boxes follow the city or utility standard, often down to the box style and the word cast on the lid. That is why SIGMA lists them on regional light castings sheets and one national list, with local patterns alongside the standard boxes.
The sheets list screw-type, slip-type and three-piece boxes with their tops, sections and bases, including heavy-duty and ductile iron versions. Fixed and adjustable risers, extensions and lids are there too, with lids cast WATER, SEWER, GAS and more, and locking lids.
Two ways to order.
Valve boxes are on each region's light castings price sheet and on the national light castings list. The sheets are all dated March 15, 2024. Not sure which region covers the job? Find your regional team.
Know the item number?
Find it on your region's light castings price sheet or the national list, then order through your waterworks distributor.
Have a spec or a drawing?
Send the standard detail or drawing to your regional team. They match it to a sheet item or quote it as a custom casting.

Every casting carries its heat number.
The heat number traces a casting to the foundry, the date and the production batch. SIGMA has inspection procedures for each castings product line, at the foundry and again at SIGMA.
5 quality steps
Inspection procedures for each castings product line, SIGMA engineers or inspectors at the foundries, material test reports, incoming inspection at SIGMA and statistical process control.
ASTM and AASHTO
Standards SIGMA works to, with federal and state department specifications, Canada's BNQ standard and the customer's own requirements.
PE certification

Questions about valve boxes and risers.
Short answers. Your regional team has the rest.
Both adjust to the depth of the valve. On a screw-type box the top section threads onto the bottom section; on a slip-type box the top slides over it. Use the type your spec calls for. The sheets list both, and three-piece boxes with a base.
A riser raises the top of an existing valve box to a new grade, for example when a street is resurfaced. The sheets list fixed risers in several heights and screw-type and slip-type adjustable risers.
The sheets list lids cast WATER, SEWER, GAS, EFFLUENT, RE-USE and CHILL, among others, and locking lids. For another word or your city's mark, ask your regional team about a custom lid.
The sheets list both: ductile iron tops, sections and lids, and Class 35 gray iron parts. If your spec names the material, ask your regional team which items meet it.
SIGMA castings are made for applications such as non-traffic, light, medium and heavy-duty loads. SIGMA works to ASTM and AASHTO standards, federal and state department specifications, Canada's BNQ standard and the customer's own requirements, and can have castings certified by an outside professional engineer on request. Confirm the rating your spec calls for with your regional team.
SIGMA sells through waterworks distributors, so your price comes from your distributor. Ask your distributor or your regional team about pricing.
