S is increased by reducing the opening of the work to improve the life of self-operated temperature control valve. Reduced S, namely increasing loss system in addition to the control valve, the dispensing temperature control valve on the lower pressure drop Shanghai Guanlong valve Machinery Co., in order to ensure flow through valve, must increase the degree of opening, while temperature control valve on the pressure drop is reduced, so that cavitation, erosion is also reduced. Specific measures are: temperature control valve is located after the throttle plate consumption drop; manually shut the pipeline valves in series Guangzhou Kaiheng Valve Co., Ltd., to obtain an ideal temperature control valve job opening up. Using this method to improve the life of self-operated temperature control valve, it proved to be very simple, convenient and effective. Valve ISO standard code What is ISO? ISO is the International Organization for Standardization (International Organization for Standardization) referred to as Shanghai and Shanghai Valve Manufacturing Co., Ltd., is a global NGO, is the field of international standardization is a very important organization Zhuhai valves, established in 1947 February 23 Japan, formerly the International Federation of National Standards Institute (ISA) Coordination Committee and the United Nations standards (UNSCC), headquartered in Geneva, Switzerland.
