Cage Guided control valve

XF62 Cage Guided Control Valve

Product Introduction

XF62 Cage Guided Control Valve is a control valve with balanced pressure and high performance. It applies to flash steam and cavitation situation caused by pressure drop, solid sleeve can protect the valve body from flash steam and cavitation. The flow channel is S type, with small pressure drop, large flow and wide adjustable range. Valve disc pilot area is large with excellent vibration-resistance. Regulation performance is compliable with IEC and GB standard. Pneumatic control valve is equipped with multi-spring diaphragm actuator with compact structure and large output. It is widely used in high-low temperature and high-pressure process pipelines which require good reliable and closure performance. With various optional materials and available designs, this valve can be used in different services and industries (such as chemical industry, gas, power station, food, metallurgy and mining, etc).
