In industries that can be impacted by just one contamination event that halts production or causes a product to be recalled, the quality of the entire fluid path is critical. When it comes to the sanitary valve used to control flow (ball valves, butterfly valves, check valves and diaphragm valves) for hygienic processing lines, you do not want to skimp on your choice of supplier. Selecting the right sanitary valve supplier goes beyond simply comparing unit prices. You need to be able to evaluate the supplier's material traceability, surface finish standards, depth of certificates and how much support they are willing to provide with documentation, etc. This guide will help you to weed out the sales jargon so that you can focus on the criteria that will help you identify a successful long-term supplier partner.
What Is a Sanitary Valve?
A sanitary valve is a type of valve specifically designed for applications where maintaining cleanliness, sterility, and avoiding contamination are of utmost importance. Unlike an industrial valve which could have internal areas that are difficult to access for cleaning due to crevices, sharp edges, and materials that could corrode or leach are not typically used in the construction of sanitary valves. Therefore, this type of valve has an interior that does not have any crevices and has been smooth finished, usually of type 304 or 316L stainless steel and it is specifically meant to either be cleaned in place (CIP) or sterilized in place (SIP). The finish on the internal surfaces of a sanitary valve that come into contact with products has been tightly controlled, with a roughness average (Ra) of 20 to 32 µ-inch being the most common for standard sanitary applications and 15 µ-inch Ra or less for high purity applications. Therefore sanitary valves are considered to be the industry standard for processing of dairy products, beer, biopharmaceuticals and food and beverage products. For a broader introduction to the entire category of hygienic fluid handling components, our article on what a sanitary fitting is provides the foundational context.
Types of Sanitary Valves and Where They Fit
A competent sanitary valve supplier should be able to provide a full range of valve types, each suited to specific process functions. Understanding the basic categories helps you assess whether a supplier has genuine depth or is simply reselling a narrow catalog.
| Valve Type | Best For | Key Characteristics |
|---|---|---|
| Sanitary Ball Valve | On/off isolation; frequent cycling | Simple quarter‑turn operation; full port for minimal pressure drop; available in 2‑piece and 3‑piece designs for easy disassembly and cleaning |
| Sanitary Butterfly Valve | Flow regulation and isolation in larger pipe diameters | Compact, lightweight, cost‑effective at larger sizes; manual, pneumatic, or electric actuation; multiple seat materials (EPDM, silicone, Viton) |
| Sanitary Diaphragm Valve | Aseptic processes; precise flow control | Completely isolates the process fluid from the actuator; weir or straight‑through body; ideal for sterile filtration and chromatography |
| Sanitary Check Valve | Preventing reverse flow | Spring‑loaded or ball‑type; must be installed in correct orientation; protects pumps and prevents cross‑contamination |
| Sanitary Globe Valve | Precise throttling and flow regulation | Linear stem movement; higher pressure drop than ball or butterfly; used where precise control is essential |
For a deeper comparison of two of the most commonly specified types, our guide on how a sanitary ball valve differentiates from a diaphragm valve explains when each is the correct choice, and our overview of various sanitary butterfly valve types and uses covers the options within that family.
How to Evaluate a Sanitary Valve Supplier
When you're comparing sanitary valve suppliers, the following criteria separate those who can support regulated production from those who simply move boxes.
Material Certifications and Traceability: A quality supplier provides full material test reports (MTRs) for every heat of stainless steel used in their valve bodies, balls, stems, and seats. The material should be traceable back to the mill, and for pharmaceutical applications, the 316L should meet the low‑sulfur, controlled‑inclusion requirements of ASME BPE. Our article on 304 vs 316 stainless steel explains why the distinction matters for corrosion resistance and cleanability.
Surface Finish and Electropolishing: The interior surface of a sanitary valve must be smooth enough that bacteria cannot anchor and product residue cannot accumulate. Mechanical polishing followed by electropolishing achieves the required finish while enriching the surface with chromium for enhanced passivity. A trustworthy supplier will provide surface roughness measurements (Ra values) on their certification documents. Our explanation of what the ASME BPE certificate means details the surface finish and dimensional standards that the most demanding pharmaceutical applications require.
Certification Depth: Look for 3‑A Sanitary Standards certification for dairy and food applications, ASME BPE compliance for biopharmaceutical, and FDA conformity for all food‑contact materials. A supplier that has invested in third‑party certification audits demonstrates a commitment to quality that a supplier with only self‑declared compliance cannot match.
Manufacturing and Testing Transparency: A capable sanitary valve supplier should be willing to show you their factory test procedures — pressure testing of every valve body, seat leakage testing, and actuator cycle testing. If you cannot visit in person, a video walkthrough of the production and testing areas is a reasonable request that any serious supplier should accommodate.
Industry Consolidation and Brand Considerations
Valves for sanitary use come from many different manufacturers. The valve manufacturing segment has experienced a lot of acquisitions and consolidation through the past 10 years, making it important to know who owns what brand, to provide insight into sourcing future supply for your application. Apple has been known for many years as the manufacturer of industrial ball valves and actuators, most recently was acquired by Aalberts N.V., a Dutch company, and now sells through their Aalberts piping systems division. PBM Valves continues to manufacture as an independent manufacturer of specialty ball valves, including some configurations for multi-port and sanitary applications, from the United States. When researching a manufacturer; whether it's a well-known brand or a new entrant into the market, it is important to establish the same qualification criteria for that supplier; documented material traceability, certified surface finishes, and evidence of having been providing both products and service to customers in your particular vertical for some time.

Frequently Asked Questions
What is a sanitary valve?
Sanitary valves are devices used to control the flow of liquid in sanitary conditions; their designs emphasize cleaning and sterilization requirements. Inner surfaces of sanitary valves typically have a 32µ-inch Ra or better polished finish, are usually constructed from 304 or 316L stainless steel, and have smooth surfaces without any crevices that may collect material when liquid is flowing through the valve. Sanitary valves are also intended to be cleaned using CIP or SIP methods and are found in many industries including brewing, dairy, food and beverage, and pharmaceutical.
Which company valve is best?
There is not a unique "best" Sanitary Valve Company available on the market. The appropriate supplier will be determined by your needs, including valve type (ball, butterfly or diaphragm), surface finish standard required by your process, certification requirements (3-A, ASME BPE, FDA) from the supplier, and if they are able to give you material traceability and test documentation from the supplier. A supplier well established in producing sanitary valves for dairy applications may not have the same certified high-purity documentation required for an injectable pharmaceutical manufacturer. Therefore, evaluate suppliers based on the criteria relevant to your process rather than by brand only.
Who bought Apollo Valve?
Apollo Valves has been acquired by Aalberts N.V., which is an industrial technology company based out of the Netherlands. Apollo will operate within Aalberts' integrated piping systems division; however, many of Apollo's products (i.e., ball valves, actuators, and other special flow control items) will still be manufactured under Apollo's brand name and still be manufactured in the industrial and commercial valve markets. The acquisition also allows Apollo to expand its distribution and have a stronger footprint in the global marketplace.
Who makes PBM valves?
PBM Valves is a US independent valve manufacturer and specializing in producing sanitary, industrial and specialty application ball valves. PBM's signature products include multiple port style Ball Valves, adjustable stem packing configurations and specialty high purity/corrosive service valves. PBM manufactures its own products at two locations in the US and caters to the Pharma, Food and Beverage, Chemical, and General Industry markets.
Choosing a sanitary valve supplier will affect your production for years and an experienced supplier will provide dependable valves (including sealing ability during CIP cleaning) as well as provide all documentation that your quality system needs and uses. Use measurable criteria such as; traceability of materials, certified finishes, pressure and seat testing results, and applicable industry certifications to evaluate a supplier rather than relying solely on flashy marketing and price. Eagle Fittings encourages you to evaluate us against these criteria as well as provide you with the documentation you will need throughout your qualification process and continued supply.
