I. Overview: 

 The SZF two-way water supply rotary valve is a four-way valve structure, valve, and consists of the electric actuator and four-way ball valve, electric actuator driven ball valve spool to turn the water supply of the pros and cons of the generator sets and transformer cooling water to the Technical to prevent one-way water supply caused by cooler blockage and affect the normal operating. 
 Second, characteristics: 
 ? A ball instead of a four valve, reducing the possible faults in the work link and reduce energy consumption, improve efficiency 
 ? Province, valves, piping, install convenient saving time. 
 ? Core part of the valve structure, good sealing performance, small size, long life, simple structure, convenient maintenance and overhaul. 
 ? Equipped with a manual mechanism. 
 Third, the technical parameters: 
 ? Working pressure: 0 ~ 1.6MPa 
 ? Working power supply: AC 380V 50HZ 
 ? Working medium: oil, water 

 ? Relative humidity: <95% RH
