Sɛnea dwumadie ne dwumadie teɛ no, wɔbɛtumi akyekyɛ mu ayɛ no:

1. Shut-off valve: twa anaa fa pipeline medium no bata ho. Te sɛ: aponkɛse valve, globe valve, bɔɔl valve, ntontom valve, diaphragm valve, plug valve.

2. Hwɛ valve no mu: siw medium a ɛwɔ pipeline no mu no kwan sɛ ɛnsen nkɔ akyi.

3. Distribution valve: sesa flow kwankyerɛ a medium no, kyekyɛ, tetew anaa fra medium no. Te sɛ afiri a wɔde kyekyɛ nneɛma, afiri a wɔde yɛ nsuo a ɛyɛ hyew, ne bɔɔl a wɔde fa akwan abiɛsa so.

4. Regulating valve: sesa nhyɛso ne nsu a ɛsen wɔ medium no mu. Te sɛ nhyɛso a ɛtew valve, regulating valve, throttle valve.

5. Ahobammɔ valve: siw nhyɛso a ɛwɔ afiri no mu no kwan sɛ ɛntra bo a wɔakyerɛ no, na fa ahobammɔ ahobammɔ a ɛboro nhyɛso so ma.
