ZJHN-B double-seat heat preservation jacket control valve is used to solve the problem that the crystallization temperature of the regulated medium is higher than normal temperature and when the fluid viscosity increases due to temperature reduction or solidification, the valve can not work properly. The valve is mainly used to keep the medium temperature and prevent the medium from being heated by steam and adopts the heat preservation jacket device at the two-seat body and the upper valve cover. Crystallization and solidification.
