2.2 Dwumadie a εfa valve no ho

Switch control: Wɔ mmere a switching adwuma nkutoo na ɛho hia no, ball valves anaaapon ano valve ahorowyɛ nneɛma a wɔtaa paw.

Flow Regulation: Sɛ ɛho hia sɛ wɔhwɛ flow so pɛpɛɛpɛ a, globe valve anaa control valves fata kɛse.

Backflow a Wosiw Ano:Hwɛ valve ahorow no muwɔde di dwuma de siw nsu a ɛbɛsan akɔ akyi no ano.

Shunt anaa Merge: Wɔde valve a ɛwɔ akwan abiɛsa anaa valve a ɛkɔ akwan pii so di dwuma de dannan nneɛma foforo anaasɛ wɔde ka bom.

2.3 Valve no kɛseɛ

Pipe Size: Ɛsɛ sɛ valve kɛseɛ no ne pipe kɛseɛ no hyia na ama nsuo no akɔ so yie. Flow ahwehwɛde: Ɛsɛ sɛ valve no kɛse di nhyehyɛe no flow ahwehwɛde ahorow ho dwuma, na ɛsõ dodo anaa ketewa dodo bɛka sɛnea ɛyɛ adwuma yiye. Installation Space: Installation space anohyeto betumi anya valve kɛse a wɔpaw so nkɛntɛnso.

2.4 Resistance a ɛyera wɔ valve mu

Nhyɛso a ɛkɔ fam: Ɛsɛ sɛ valve no ma nhyɛso a ɛkɔ fam no so tew na amma ɛrenka nhyehyɛe no adwumayɛ.

Flow channel design: Full bore valves, te sɛ full bore ball valves, tew drag loss so.

Valve Type: Valve ahorow bi te sɛ butterfly valve no ntumi nnyina ano kɛse bere a wɔabue no, na ɛma ɛfata ma mmere a nhyɛso a ɛba fam no kɔ fam.

2.5 Adwumayɛ mu hyew ne adwumayɛ nhyɛsoɔ a ɛwɔ valve no mu

Ɔhyew a ɛkɔ soro: Ɛsɛ sɛ nneɛma a wɔde yɛ valve no dannan ne ho ma ɛne nsu mu hyew hyia, na ɛsɛ sɛ wɔpaw nneɛma a ɛko tia ɔhyew wɔ mmeae a ɛhɔ yɛ hyew kɛse anaasɛ ɛba fam.

Nhyɛso dodow: Ɛsɛ sɛ valve no tumi gyina nhyehyɛe no adwumayɛ nhyɛso a ɛsen biara ano, na ɛsɛ sɛ nhyɛso kɛse nhyehyɛe no paw valve a nhyɛso kɛse wom.

Ɔhyew ne nhyɛso a wɔaka abom: Ɔhyew a ɛkɔ soro ne nhyɛso kɛse a atwa yɛn ho ahyia no hwehwɛ sɛ wosusuw nneɛma ahoɔden ne sɛnea ɛsɔ ano ho titiriw.

2.6 Nneɛma a wɔde yɛ valve no

Nneɛma a ɛko tia nsɛe: Paw nneɛma a ɛfata a egyina nsuo a ɛtumi nsɛe so, te sɛ dadeɛ a ɛnyɛ den, Hastelloy, ne nea ɛkeka ho.

Mfiri ahoɔden: Ɛsɛ sɛ valve ade no nya mfiri ahoɔden a ɛdɔɔso na ama atumi agyina adwumayɛ nhyɛso no ano.

Ɔhyew a wotumi sesa: Ɛsɛ sɛ ade no dannan ne ho ma ɛne ɔhyew a wɔde yɛ adwuma no hyia, baabi a ɛhɔ yɛ hyew kɛse no hia nneɛma a ɛko tia ɔhyew, na baabi a ɔhyew a ɛba fam no hia nneɛma a ɛko tia awɔw.

Sikasɛm: Sɛ wudi adwumayɛ ho ahwehwɛde ahorow ho dwuma a, paw nneɛma a sikasɛm yɛ papa.
