Pneumatic insulation jacket single-seat control valve Overview: Air insulation jacket single-seat control valve, referred to as control valves or valve jacket insulation is one of the CV3000 series of products. The valve is for applications that require thermal insulation applications. When the crystallization temperature of the process medium is less than the case of temperature or fluid temperature decreases, causing the fluid viscosity enhancement or emerged during solidification, then the addition of a steam jacket insulation assembly in the valve body and the valve cover, and to give the process medium dominated by the need to meet the process. Leakage control valve suitable ANSI B16.104 standard. Pneumatic control valve is equipped with multi-spring diaphragm actuator, its compact structure, large output force. This product is suitable GB / T4213-92 standards. 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 Anhui two-piece ball valve, the valve moves up and down to play a guiding role. The guide sleeve holes, 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 ex-factory two-piece ball valve, easy to ensure 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 two-piece ball valve principle, which is another characteristic of the force on the spool sophomore medium-valve, that is not counterweight large, more serious, especially in the case of high differential pressure, large diameter, so only for low dropout applications. Otherwise, it should be chosen thrust of the actuator, or with positioner.
