Single-seat control valve structure parameters through single-seat control valve body has only one core and valve seat seal butterfly, DN≥25 how much money a hard seal butterfly valve, the valve is double oriented (now fine small single-seat control valve has been changed a single guide); DN≤25, the spool is a single guide. The valve is generated abroad in the 1940s and 1960s by the domestic joint design, which is characterized as follows: ① Because only one spool, it is easy to ensure the seal, a small amount of leakage, but not completely cut off. The standard leak was 0.01% Kv, and therefore require a small amount of leakage is suitable for the occasion. After further design can be used as a shut-off valve. ② Because only one spool unbalanced thrust, generated great pressure on the spool. Before setting valve pressure after P1, the valve pressure P2, stem diameter ds, seat diameter dg insulation jacket single-seat pneumatic control valve Overview: insulation jacket single-seat pneumatic control valve seal butterfly how to sell, referred to regulate jacket insulation valve or valve, 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 solidification seal butterfly emerged the manufacturer, then the addition of a steam jacket insulation assembly in the valve body and the valve cover, and to give the process medium contentment process needs to dominate. 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.
