Expanding Gate Valve
* Full bore design eliminates efficiently pressure drop and vortex, and eliminates washing by solids in fluid. * Gate use expanding type structure. * Achieve low torque operation and low wastage during open and close. * Metal seal is used between bonnet and body. * Soft seal or metal seal is used between gate and seat. * Inject sealant through injection valve to improve seal performance. * Working Pressure: 2000PSI¡«10000PSI * Nominal Bore: 1.13/16"¡«7.1/16" (46mm¡«180mm) * Working Medium: oil¡¢natural gas¡¢mud and gas containing H2S¡¢CO2 * Working Temperature: -46¡ãC¡«121¡ãC£¨Class LU£© * Material Class: AA¡¢BB¡¢CC¡¢DD¡¢EE¡¢FF¡¢HH * Specification level: PSL1-4 * Performance Requirement: PR1-2
JFC Series Gate Valve
* Full bore design eliminates efficiently pressure drop and vortex, eliminates washing by solids in fluid. * Special seal type lower switch torque. * Mental-to-mental seal is used between bonnet and body, gate and seat rising. * Mental-to-mental seal between gate and seat, and the surface is weld overly with hard alloy, which has feature of corrosion resistance and washing resistance. * Retainer plate fix seat ring insuring good stability. * The stem designed with back seal, can replace stem sealing under pressure. * One side of bonnet is designed with sealant injection in order to supply sealant and improve seal and lubrication performance of gate and seat. * Can complete with different pneumatic (hydraulic) actuator upon user¡¯s requirements. * Working Pressure: 2000PSI¡«20000PSI * Nominal Bore: 1.13/16"¡«9" (46mm¡«230mm) * Working Medium: oil¡¢natural gas¡¢mud and gas containing H2S¡¢CO2 * Working Temperature: -46¡ãC¡«121¡ãC£¨Class LU£© * Material Class: AA¡¢BB¡¢CC¡¢DD¡¢EE¡¢FF¡¢HH * Specification level: PSL1-4 * Performance Requirement: PR1-2
