Mantsoe a reng "valve e phethahetseng" le "vanematic" hangata "hangata e sebelisoa ka mokhoa o lekanang, empa li bua ka likarolo tse fapaneng tsa sistimi ea lihlala. Ha re hlakiseng khethollo lipakeng tsa tse peli:
Volnoid valate:
Valve e sotlehang ke mofuta oa valve e sebetsang ka matla a matla, e leng koluoa ea terata e hlahisang matla a khoheli ha a feta a feta.
Li-valves tse solenoid li ka sebelisoa ho laola phallo ea metsi kapa likhase tse fapaneng, ho kopanyelletsa le moea, metsi, oli le mecha ea litaba le mecha ea litaba.
Liphara tsena ha li fetohe 'me li tla ka mokhoa o fapaneng, tse kang tse peli-, tse tharo {{{{{{ Li ka ba buloa, hangata li koetsoe, kapa li na le tlhophiso e kopaneng.
Li-valves tse solenoid li fumana lits'ebetso tsa indasteri e fapaneng, ho kenyelletsa litsamaiso tse fapaneng tsa Ponesicatic, tsa Hydraulic, taolo ea metsi le tse ling.
Vetamatic valve:
Veve ea Ponematic ke valve e etselitsoeng ho sebelisoa ho Pneumatic (e nang le tlhophisong ea moea).
Likhathatso tsa Ponematic li laola moea o hatelletsoeng ka litsamaiso tsa semeng, li laola motsamao oa baetsi ba li-apneimatic, meqomo le lisebelisoa tse ling.
Li-valves tsa Ponematic li ka tla ka mefuta e fapaneng, tse kang li-valves tse laolang taolo, li-valves tsa khatello, li-valves tsa taolo, le tse ling.
Le ha li-valve tse ling tsa Ponetic li ka sebelisoa ka letsoho, tse ling li etselitsoe ho etsoa ke mehloli ea kantle, ho kenyelletsa le sononoids.
Ka kakaretso, phapang ea bohlokoa e lula e le eona lenaneong:
Volnoid valate:E bua ka mofuta oa mochini oa boithabiso oa valve, moo solenoid e matlafatsang a sebelisetsoang ho laola valve.
Vetamatic valve:E bua ka moelelo oa ts'ebeliso, ho bonts'a hore valve e etselitsoe hore e sebelisoe lits'ebetsong tsa limela, moo moea o nang le tlhokahalo e leng oa ts'ebetso.
Ho bohlokoa ho hlokomela hore valve ea pneumatic e kanna ea se ke ea kenyelletsa "solenoid" ho etsa lipatlisiso. Maemong a mangata, haholo-holo ka mekhoa e ikemetseng, li-valves tsa Ponematic li etsoa ke Solioids ho fihlela taolo le lits'ebetso tsa Ponematic.
