Brass mini ball valves are commonly used for precise flow regulation in confined spaces in applications like plumbing, HVAC, irrigation, industrial equipment, and more.
Key advantages are the compact size, corrosion resistance, durability, ease of operation, quick open/close function, and versatility for a wide range of applications.
Common sizes range from 1/4" to 2" diameter but specialised valves are made smaller or larger. Choosing the proper size is important for optimal flow.
They consist of a brass body, chrome plated brass ball with a bored passageway, seats or seals, stem, and handle for manual operation.
Threaded ends like BSPP or NPT, compression, push-to-connect, solder, flanged, and socket are typical end connections.
Many have pressure ratings up to 800 psi, but specialised high pressure mini ball valves can handle pressures exceeding 5000 psi.
Common ratings range from -4°F to 250°F. Extended temperature models can handle up to 400°F.
With proper maintenance, these valves typically have a lifespan of 30+ years. The brass body holds up well over decades of use.
Annual inspection of the seal, packing, and ball movement is recommended. Lubricating the stem and ball helps extend life.
Electric actuators can be coupled with the valve stem to automate opening and closing of the valve.
Applicable certs include MSS SP-110 for quality and performance as well as WRAS for potable water usage.
Yes, they can be disassembled and repaired by replacing seals, seats, stems, or other internal components if damaged.
