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 pin fixed pin fixed to be the stem and the valve power station 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. Anhui valve guide sleeve hole, connecting the body cavity and the valve 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 a force on the spool of big media, which greatly reduced unbalanced force pressure valve, especially in the high-pressure differential, in the case of large diameter are more serious, so only for low dropout applications. Otherwise, it should be chosen thrust actuator valve wholesale price, or with positioner.
