Product Overview
Qhov kev sib koom ua ke ob lub pob valve tso cai rau kev saib xyuas tag nrho inline yam tsis muaj kev cuam tshuam ib puag ncig cov kav dej. Qhov tseeb lub koomhaum tsim qauv muaj cov ntsiab lus hloov kho dual tus neeg nqa khoom thiab cov khoom siv kawg uas tshem tawm ntawm lub cev lub cev, muab cov pab pawg ua haujlwm ncaj qha rau hauv cov ntsaws ruaj ruaj, O-rings, thiab pob khoom.
Engineered rau kev lag luam dej tuav, kev kho dej, thiab kev ua tshuaj lom neeg, lub hauv siab bore du minimizes kev sib txhuam taub hau poob thiab tiv thaiv cov khib nyiab buildup thaum lub sij hawm tas mus li kev pab cuam.
Cov yam ntxwv tseem ceeb ntawm cov khoom
Dual Block / True Union Structure:Ob qhov kawg kev sib txuas unthread ntawm nws tus kheej, ua kom tshem tawm cov cartridge thaum cov kab siab tseem nyob hauv dej (thaum kaw).
Adjustable Foob Retainer:Threaded seal carrier tso cai rau phau ntawv ua ntej - thauj khoom hloov kho ntawm PTFE lub rooj kom kho rau hnav yam tsis tau tshem lub cev.
Blowout-Cov pov thawj Stem:Internal qia loading tiv thaiv qia ejection nyob rau hauv siab surges los yog system kab spikes.
Full Port Flow Path:Internal pob orifice ntais ntawv teem sij hawm 80 yeeb nkab IDs, tswj tag nrho cov txaus txaus thiab txo cov kev xav tau ntawm lub taub hau.

Ergonomic Manual Handle (nrog cov cuab yeej sib xyaw ua ke)
Pneumatic Actuator (Ob chav ua yeeb yam / Caij nplooj ntoos hlav rov qab)
Fais Actuator (24V DC / 110V AC / 230V AC, On- Tawm / Modulating)
Daim ntawv thov -Kev txiav txim siab tsim tshwj xeeb
Thermal Expansion:PVC linear expansion coefficient yog 0.08 hli / m· degree. Cov yeeb nkab khiav tshaj 30 meters yuav tsum tau nthuav dav loops kom tsis txhob sab -loading lub valve lub cev unions.
Siab De- ntsuas:Kev khiav hauj lwm siab txo qis thaum media kub nce:
- 73 ° F (23 ° F):100% PN16 (232 PSI)
- 110 ° F (43 ° F):60% PN16 (139 PSI)
- 140 ° F (60 ° F):22% PN16 (51 PSI)
Dej Rauj Risks: Fast quarter-turn closure can create pressure transients. For high-velocity lines (> 5 ft/s), motorized actuators with adjustable travel speeds (>10 vib nas this) tiv thaiv hydraulic shock.

FAQ
Q: Lub valve no puas tuaj yeem muab kev pabcuam raws li cov kab tag nrho?
A: Tsis yog. Koj yuav tsum depressurize lub raj xa dej ua ntej loosening lub union txiv ntseej. Kaw lub valve thaiv cov dej ntws tawm, tab sis cov dej ntws qis hauv lub valve lub cev yuav tsum tau muab tso rau kev nyab xeeb ua ntej kev pabcuam.
Q: Lub hom phiaj ntawm kev tsim - yog dab tsi?
A: Qhov kawg ntawm tus tuav tshem tau muaj ob lub puab tsaig uas haum rau hauv cov qhov ntawm cov khoom siv hauv cov xov hlau, tso cai rau ntawm - qhov chaw hloov lossis hloov lub rooj zaum pob tsis muaj cov cuab yeej tshwj xeeb.
Q: Kuv yuav xaiv li cas ntawm EPDM thiab FKM O-rings?
A: Xaiv EPDM rau kev kho dej dav dav, khoom siv hauv nroog, thiab cov kua qaub me me / alkali. Xaiv FKM thaum tuav cov kua qaub, roj, cov kuab tshuaj, lossis cov tshuaj chlorine gas.
Q: Puas yog qhov ntev ntawm lub qhov (socket) sib haum nrog Schedule 80 PVC yeeb nkab?
A: Yog. Qhov (socket) xaus raws li ASTM D2467 qhov ntev rau lub sijhawm 80 PVC yeeb nkab haum. Metric socket xaus ua raws li DIN 8063 kuj muaj nyob rau ntawm kev thov.
Q: Puas tuaj yeem PVC qhov tseeb lub koom haum pob li qub tuav slurries lossis abrasive media?
A: Cov khib nyiab pov tseg tuaj yeem khawb PTFE lub rooj zaum thiab tau qhab nia ntawm pob, ua rau lub rooj hla dhau sijhawm. Tshem cov kab nrog dej ntshiab tom qab hloov cov xov xwm uas muaj cov khoom seem saum 50 microns.
Q: Dab tsi ua rau kev sib koom ua ke cov txiv ntoo rov qab - tawm hauv siab - kev vibration skids?
A: Kev vibration los ntawm cov twj tso kua mis nyob ze tuaj yeem txo txoj kev sib koom tes. Rau siab - kev vibration installation, thov peb locking union txiv ntseej xaiv los yog nruab cov yeeb nkab txhawb nqa nyob rau hauv 5 yeeb nkab diameters ntawm ob sab ntawm lub valve.
