| ◇ With balance type characteristic,GYL-40000 series have wide applications, in 40000 series, the 40700 series,40800 series,40900 series is designed focused on high pressure drops, effectively reduce the effects of cavitation and the noise in the high pressure drops services.
◇ GYL-40000 series have favorable Interchangeability, be reached different flow characteristics by replacing different cage, to get much higher precision of control. Can be reduced noise, dispelled the effects of cavitation by replacing trim. |

◇ Cage Guided control valve size is in common use for 1″-12″, actuator for standard diaphragm type, It’s content to most industrial process control.
◇ GYL-40000 series have some kinds Connecting format: Flanged (BF,RJ, concavo-convex); Weld ends (2 " below to be SW,3" above to be BW) |

◇ GYL-40000 series have some standard pressure grade. JIS， ANSI?CLASS，JB/T79-94
◇ By metal seat,the suitable temperature range is -196℃— +538℃,and by soft seat,the suitable temperature range is -45℃— +200℃。 |

◇ The most excellent of cage guided structure control valve is balance characteristic, for plug balance port’s function, fluid pressure acted on static unbalance force of plug, it reduced unbalance force, then valve can be configured actuator smaller than conventional single seat valve.
◇ The most simple structure of cage guided control valve is twin-seat, twin-seat structure is applicable to situation that requirement of leakage is not high.
◇ Cage guided single seat control valve have a sliding seal between plug’s top with cage. by seal’s function, dispelling the leak that upriver fluid entered low-pressure downriver system. So it have the tight closed characteristic as conventional single seat valve, moreover have balance characteristic. |
