Main features:

JGSC Dual-oriented cage single-seat control valve not only have feature of  common single-seat valves, but also has good stability, anti-erosion, anti-cavitation, etc..it’s more suitable for harsh conditions of the working conditions.

Just replace the low-noise on the sleeve can change JGSC  Dual-oriented cage single seat control valve into JGCN Dual-guided low-noise cage single-seat control  valve.it can significantly reduce the noise of compressible fluids, it’s more suitable for high-pressure differential gas occasions.

The valve has compact valve body, fluid channel is S streamlined. own advantages of small loss of pressure drop, flow large, adjustable range wide etc. Control valve equipped with muti-spring pneumatic films implementing structure, compact structure, powerful output force , suitable for occasion that require high closing performance and  reliability  in high temperature and high pressure differential.
