ZECO electric gate valve is a gate valve controlled by an electric actuator. It can operate the gate valve remotely through an electric device, which is usually installed in the upper part of the gate valve. Electric actuators are divided into three, one is a straight stroke: the valve up and down to control the valve opening (such as: single seat valve, double seat valve, sleeve valve, Y valve, etc.); The other is a quarter-turn: driven Angle of the valve is in 0 ~ 90 ° rotation to control the valve opening (such as: eccentric butterfly valve, ball valve, rotary valve, plug valves, etc.); The last one is multi-turn electric actuators (360 ° Angle >) is suitable for the gate valves, globe valves, etc. Electric actuator output shaft rotation is more than a week, that is greater than 360 °, generally need more than one ring valve opening and closing process control can be achieved. ZECO is a professional manufacturer of electric gate valves, high quality creates ZECO brand.
1. Spacer ring in conjunction with packing is used in gate valves of 300 class and above while 150-class valve is only fitted with packing; packing with lantern ring is available upon customer request;
2. Flexible wedge is able to compensate for seat surface distortion and body deformation caused by piping stress;
3. Blowout retention design: the tapered backseat face firmly contacts backseat of bonnet, the strength of bonnet-wedge connection exceeds that of bonnet thread root;
4. ZECO electric gate valve is standard equipped with AUMA electric actuator. Other brands can be customized according to customers' requirements.
