Pressure safety solutions for pressure-intensive processes
At Super Quali Cast, we create investment castings for safety relief valves that prevent chatter and system failure in pressure-critical systems. Our safety relief valve castings are produced in our state-of-the-art foundry and shipped to domestic and international valve manufacturers and OEMs. Common end users include chemical plants, oil refineries, HVAC systems, and other industries that depend on optimal pressure conditions.
We manufacture and supply investment castings for safety relief valves to businesses in the US, the UK, Canada, Brazil, and the EU. We also export to manufacturing concerns in the UAE, Saudi Arabia, Qatar, Japan, and Taiwan.
Our Manufacturing Process of Safety Relief Valve Casting
Molding and Investing
Immersing molds into a ceramic slurry to create the cast.
Dewaxing
Placing the cast in a furnace to melt the wax and leave behind an accurate net shape.
Pouring
Filling the negative net shape with the molten metal of choice.
Heat Treatment
Knocking out the components and heat treating them to enhance material strength.
Machining
Making final adjustments, including removing excess materials and adding threads to holes.
Final Inspection
Non-destructive testing handled by level-2 personnel, with provision for Intergranular Corrosion Test.

Frequently Asked Questions
What factors should be considered when selecting investment castings for safety relief valves?
Pay attention to pressure rating, material used, material hardness, coatings used (important if the part in question will be exposed), operating temperature range, and discharge capacity.
When is safety relief valve investment casting the right choice?
Safety relief valve investment casting is the right choice when the size of the valve is between small and medium. For large valves, sand casting is the more suitable option.
What are the benefits of using safety relief valve castings?
Manufacturers and OEMs typically find that safety relief valve castings, such as those produced by Super Quali Cast, need little to no machining. Investment casting is economical in producing complex designs in near net shape, repeatedly.
Is a relief valve the same as a safety valve?
While a relief valve is not the same as a safety valve, they have similar functions, and the two terms are used interchangeably in the industry.
Is the 3% rule important when choosing investment castings for safety relief valves?
Yes, the 3% rule is important when choosing investment castings for safety relief valves. This is the gold standard for safety and prevents chatter in otherwise functional systems.
