Plumbing Valves
How to choose plumbing valves
Manual vs electric actuation
Pick a manual angle stop valve for a sink, or an electric globe valve for automated control. Manual is simpler, electric saves legwork.
Material and weight
Choose stainless steel or copper for drinking water plumbing, but accept the weight versus plastic or aluminium hardware.
Colour coding
Match the colour mark (red/blue or yellow) to your line type so staff do not mix up runs.
Sub-type fit
Decide between plumbing fittings and hardware supports based on whether you need to stop flow or just hold pipe.
Pressure rating vs heft
Cast iron handles pressure well. Its weight means you need a bracket, while plastic is light but lower rated.
What's good
- Manual side valves need no power supply.
- Stainless steel and copper plumbing valves resist corrosion in bathroom and kitchen use, extending their working life.
- Electric globe valves with position controllers suit automated systems where manual reaching is impractical.
- Plastic and aluminium hardware fittings keep weight down on large support builds.
- Coloured tags (red/blue or yellow) on plumbing fittings make line types obvious at a glance.
Things to watch
- Cast iron flange valves are durable but heavy. They are awkward to seat without extra supports.
- Solenoid and electric actuator valves need a power source, adding wiring complexity that a manual valve avoids.
- Plastic and rubber parts suit low pressure but wear faster under high bar stress than steel bodies.
- Small air solenoid valves move fast yet push limited flow, so they are wrong for main supply lines.
Care & maintenance
Clean bodies
Wipe stainless steel valve bodies with a dry cloth. This stops limescale on the threads.
Cycle manuals
Exercise manual globe and side valves every few months so the spindle does not seize shut.
Inspect seals
Check rubber seals on solenoid valves for cracks if the unit sits idle through a cold spell.
Torque flanges
Keep flange bolts on cast iron globe valves torqued evenly to avoid stem leaks.
