Application
High pressure regulating valve includes high pressure sleeve single seat regulating valve and high pressure cage regulating valve two structures, used in power station, metallurgy, chemical industry and other high temperature and high pressure occasions.
Characteristic
• High pressure sleeve single seat regulating valve with top guide structure, has the characteristics of simple structure, compact, small pressure drop loss, large flow, wide adjustable range, good earthquake resistance; It is widely used in high pressure fluid with high leakage requirement.
• High pressure cage type regulating valve adopts pressure balance structure, with good dynamic stability, can withstand the pressure difference, high adjustment accuracy characteristics; It is widely used in high-pressure situations requiring low noise, stable regulation and small cavitation and corrosion.
