Overview,

Two-way rotary valve of water supply is a four-way valve ball valve structure, composed of electric actuators and spool valves, electric actuator driven in ball valve core, the implementation of generator and transformer cooling water is water, reverse technology, prevent unidirectional water cooler blocking and affect the normal operation of the unit.

Second, the characteristics of

Replace the four regulator with a ball valve, reduce the possible faults in the work link, reduce the energy consumption and improve the work efficiency.

Save valves and piping, installation is convenient time.

The core part of the structure of ball valve, sealed performance is good, small volume, long service life, simple structure, convenient maintenance.

The seal since the compensation system, after sealing surface wear, stainless steel spring will seal face to the valve core, to generate enough sealing force

Equipped with manual institutions.

Three, working principle

Is water supply 1, 4, 2, 3 closed, reverse when water supply 2 or 3 open, 1, 4 closed

If use SZF two-way rotary valve of water supply, a valve can achieve the above, the water supply switch

Electric actuators cross steel ball valve core rotates, every turn 90 Angle, water supply way switch at a time.
