LN82 series are LN8 series pressure imbalance structure products one of two basic bushing and seat double direction, flow capacity, good dynamic stability, porous cylinder valve core design, realizes the throttle and reasonable separation on sealing surface, sealing surface is not affected by high velocity directly erosion, sealed performance is good and reliable to prevent flash, cavitation resistance, noise reduction. The purpose of fast clean medium suitable for velocity, especially for the high pressure difference of gas control.
3. pneumatic actuator of globe control valve
The standard mate of LN8 series is AM8 Multi-spring pneumatic diaphragm actuator, which can be used in many conditions with the features of strong output force, high reliability, long lifespan and extensive application. The output force changes with the number of springs. The high stress resistant diaphragm, bearing maximum pressure of 0.5 MPa air supply, gives control valve a reliable shutoff. This type of actuator has a long life cycle with more than 1 million times.
