Haiqiao Yap Valve Manufacturing Co., Ltd. [ZAJO electric cut off valve / electric O-Ball] manufacturer, with large spot to ex-factory sales! Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! First, the electric cut off valve Product Overview ZAJO electric ball valve is the use of O-core structure, also known as O-type electric valve. Electric cut off valve which has a compact structure, small size, light weight, and the end face of the flange seat from the past, less material retention, superior sealing performance characteristics. Electric switch valve is suitable for cutting two occasions, the connection valve and actuator direct connection, with no need for electric actuator servo amplifier, the input 220VAC power to control operation. ZAJO electric cut off valve has a simple connection, compact structure, small size, light weight, low resistance, stable and reliable operation. Usually suitable for sealing demanding situations, the electric O-valve, electric cut off valve is widely used in chemical, petroleum, pharmaceutical, light industry, automatic control.
