Industrial Valve Selection — Quick Reference
Industrial valves control FLOW + DIRECTION + PRESSURE + LEVEL of fluids + gases. AIMS stocks deep range across BALL + GATE + BUTTERFLY + CHECK + NEEDLE + GLOBE valves in materials matched to media + pressure + temperature.
| Valve Type | Best For |
|---|---|
| Ball Valve | Quick on/off — see ball valves |
| Gate Valve | Full open OR closed only — see gate valves |
| Butterfly Valve | Large bore + on/off + light throttle — see butterfly valves |
| Globe Valve | Throttling + flow control — see globe valves |
| Check Valve | One-way flow + non-return |
| Needle Valve | Precise flow throttling |
| Pressure Relief Valve | Safety + pressure limit |
| Solenoid Valve | Electric automation + remote actuation |
| Material (Brass / SS / Cast Iron / Bronze) | Match to media + pressure + temperature |
| Pressure Class (ANSI / Table D-F) | Match to system pressure |
Critical: Match valve TYPE to FUNCTION — ball/gate = on/off; globe/needle = throttle; check = one-way. Match MATERIAL to media (stainless for chemical + food; brass general; cast iron heavy industrial). Pressure rating MUST exceed system maximum. Companion: ball valves, gate valves, butterfly valves, globe valves, pumps + fluid handling.
Industrial valves control the flow, direction, pressure or level of fluids and gases in a pipeline. AIMS stocks a deep range across ball valves, gate valves, butterfly valves, check valves, needle valves and globe valves — in materials matched to the duty (brass and bronze for water and air, stainless 316 for chemical and food, cast iron and ductile iron for waste and bulk lines).
Selecting the right valve
- Ball valves — fast quarter-turn on/off; the workhorse for water, air and oil isolation.
- Gate valves — full-bore flow with low pressure drop; best for fully-open / fully-closed service, not throttling.
- Butterfly valves — compact, lightweight isolation and modulation in larger line sizes. See our Butterfly Valve Guide.
- Check valves — one-way flow to prevent backflow and water hammer.
- Needle valves — precise flow control for instrumentation and metering.
Pressure rating (PN16, PN25 etc), seat material (PTFE, EPDM, NBR, Viton), and end connection (BSP, NPT, flanged AS 4087 / ASME B16.5) all matter. If you're spec'ing a system, talk to our team — we'll match the valve to the line, not the other way around.

People Also Ask — Valves
Q: Why would I pick a globe valve over a ball valve for a throttling application?
Ball valves give fast quarter-turn on/off control and are the workhorse for water, air, and oil isolation, while globe valves are used for throttling and flow control rather than simple isolation.
Q: Why doesn't a gate valve suit throttling duty?
Gate valves give full-bore flow with low pressure drop and are best for fully-open or fully-closed service, not throttling.
Q: What's a check valve used for?
One-way flow to prevent backflow and water hammer.
Q: When would a needle valve be specified over a ball valve?
Needle valves give precise flow control, suited to instrumentation and metering, where a ball valve's on/off action isn't precise enough.
Q: What material should I specify for a valve handling chemical or food-grade media?
Stainless steel (316) is specified for chemical and food-grade media, brass for general use, and cast or ductile iron for waste and bulk lines.
Q: What valve details need to be matched to the pipeline system?
Pressure rating (such as PN16 or PN25), seat material (PTFE, EPDM, NBR, Viton), and end connection (BSP, NPT, or flanged to AS 4087 / ASME B16.5) all need to match the pipeline system.
