Electric Actuator
Performance Features
Shell - The shell is made of hard aluminum alloy, anodized and polyester powder coated, with strong corrosion resistance. The protection level is IP67, NEMA4 and 6, and IP68 type is available.
Motor - fully enclosed squirrel cage motor, small size, large torque, small inertia force, insulation grade F, built-in overheating protection switch to prevent overheating damage to the motor.
Handle structure - the design of the handle ensures safety, reliability, labor saving and small size. When power is off, pull the handle for manual operation. When not using it manually, place the wrench in the wrench clip for easy use.
Indicator--The indicator is mounted on the central axis and allows the valve position to be observed. The lens adopts a convex mirror design, which does not accumulate water and makes observation more convenient.
Dryer - used to control the temperature, prevent moisture condensation inside the actuator due to changes in temperature and weather, and keep internal electrical components dry.
Sealing - good sealing, standard product protection level is IP67, and IP68 protection level is optional.
Electric Butterfly Valve
Overview
Butterfly valve is a valve that uses a disc-type opening and closing part to rotate back and forth about 90° to open, close and adjust the fluid channel. Butterfly valves not only have simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and rapid operation, but also have good flow adjustment function and closing sealing characteristics. One of the fastest growing valve varieties. Especially in industrially developed countries such as the United States, Japan, Germany, France, and Italy, butterfly valves are widely used. The varieties and quantities used are still expanding, and they are moving towards high temperature, high pressure, large diameter, high sealing, long life, It has excellent regulating characteristics and multi-functional development in one valve. Its reliability and other performance indicators have reached a high level, and it has partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valves will become the dominant valve form in a foreseeable short time, especially in the fields of medium and low pressure applications of large and medium-sized valves.
Connection Method
According to different connection methods, electric butterfly valves can generally be divided into the most common electric wafer butterfly valves and electric flange butterfly valves. The sealing materials include soft seals (normal temperature and pressure) and metal seals (high temperature and high pressure). The working power supply usually includes: AC220V, AC380V, DC24V, the input signal includes 4~20mA 0~10v and other weak current signals. Finally, according to the control form, it is divided into on-off ype and regulating type. The on-off type plays the role of switch; the regulating type is used to adjust the flow and can accurately It is also a relatively expensive valve to adjust the flow to a thousandth of a degree.
