Through single-seat control valve Detailed structure through single-seat control valve from the valve, valve seat, valve guide sleeve, bonnet, stem and packing and other parts. Plug and stem together. The method can be used to connect an interference fit or threaded pins fixed valve pin fixed wholesale price, you can also power station valve stem and valve core one car out. Between the valve cover and valve body has a guide sleeve, the spool up and down movement serves as a guide. Guide sleeve valve orifice sales price, and the valve body cavity communicating the outlet end. Guide sleeve cavity medium can easily flow into the outlet end of the valve through the hole, it does not affect the movement of the spool. Through single-seat control valve of a spool valve body and a valve seat only. Characterized by a small amount of leakage, easy to guarantee the seal. There are regulated and cut-off the structure. Their difference lies in the shape of the spool. Adjusting the shape of the plunger-shaped spools; shape cut spools of flat or tapered valve manufacturer, it's another feature is medium large force on the spool valve, that imbalance force, particularly in the high pressure difference, the more severe the case of large diameter, so only for low dropout applications. Otherwise, it should be chosen thrust of the actuator, or with positioner. Percentage characteristics and linear characteristics [℅V] [LV] Material:: Electric high voltage cage type regulating valve components Spool type: piston ring seals or pressure-balanced valve plug flow characteristics in combination with the body, trim material combinations and operating temperature range · seat allowable leakage electric high voltage cage type regulating valve actuator type :DKZ Series actuators; 381L series electric actuators; PSL series electric actuator type electric-close valve action or electric valve open valve _ quote _ Tianchang instrument linked instruments provided by the United Instrument Sales Co., Ltd.
