Ma valve osindikizira pachipata amadzimadzi amadziwika ndi mphero yoyendayenda, yomwe imasunthidwa ndi ntchito ya mtedza wa tsinde. Mphepeteyo imayenda perpendicular kwa njira yothamanga.
Mavavu a pachipata ndi mapangidwe osindikiza kawiri, nthawi zambiri amakhala ndi kutsika kochepa kwambiri akamatseguka, amapereka kutseka kolimba akatsekedwa kwathunthu.
Ma valve osindikizira pachipata cha Pressure seal amagwiritsidwa ntchito ngati kuthamanga kwambiri, nthawi zambiri kupsinjika pamwamba pa 100 bar. Chinthu chapadera cha boneti yosindikizira yosindikizira ndi chakuti chisindikizo cha thupi-boneti chimayenda bwino pamene kupanikizika kwa mkati mkati mwa valve kumawonjezeka.
Ntchito zazikuluzikulu ndi izi: mafakitale a petrochemical, mabwalo a nthunzi, ma boiler, mafuta ndi gasi, malo opangira magetsi.
Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi: nthunzi, condensate, madzi opangira boiler
Kuthamanga kwapadera kwa valve ndi 900, 1,500 ndi 2,500 mapaundi.
Mapangidwe a ma valve a pakhomo la JLPV ali motere:
1.Kukula: 2 "mpaka 48" DN50 mpaka DN1200
2.Kupanikizika: Kalasi 900lb mpaka 2500lb PN160-PN420
3.Zinthu: Chitsulo cha carbon ndi chitsulo chosapanga dzimbiri ndi zipangizo zina zapadera.
NACE MR 0175 anti-sulfure ndi anti-corrosion zitsulo zipangizo
4.Kulumikizana kumatha: ASME B 16.5 mu nkhope yokwezeka (RF), Flat face (FF) ndi Ring Type Joint (RTJ)
ASME B 16.25 mu matako kuwotcherera malekezero.
5.Kukula kwa nkhope ndi nkhope: kugwirizana ndi ASME B 16.10.
6.Kutentha: -29 ℃ mpaka 580 ℃
Ma valve a JLPV amatha kupangidwa mumitundu yonse yazinthu kuti akwaniritse zofunikira zosiyanasiyana kuchokera kwa makasitomala, makamaka mulingo wa NACE.
Mavavu a JLPV amatha kukhala ndi zida zamagetsi, ma pneumatic actuators, ma Hydraulic actuators, Magetsi, ma bypass, zida zotsekera, ma chainwheel, zimayambira zowonjezera ndi zina zambiri zilipo kuti zikwaniritse zosowa za makasitomala.
