Introduction SZF two-way rotary valve the water supply valve structure is a four-way valve, the actuator and the four-way ball valve, ball valve electric actuator drive spool rotation, to achieve power stations forward and backward technology, water supply caused prevent unidirectional coolers reduce clogging of the generator cooling efficiency and affect the normal operation of the unit. Features 1, with a ball valve instead of four, reducing the work possible fault links, reduce energy consumption, improve work efficiency. 2, saving valves, piping, installation convenience province. 3, the core part of the ball valve structure, good sealing performance, small size, long life, simple structure, easy maintenance and repair. 4, sealed self-compensating system, after the sealing surface wear, stainless steel spring will push the sealing surface of the valve body, in order to generate sufficient sealing force. 5, equipped with a manual mechanism. Technical parameters 1, working pressure: 0 ~ 1.6Mpa 2, working medium: oil, water 3, Power Supply: AC380V 50HZ 4, relative humidity: <95% RH 5, ambient temperature: 0 ~ 50 ℃
