Description
Industrial Valve Motorized Butterfly Valve (also known as flap valve) is a regulating valve with a circular valve disc or disc as the closing part. It is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical, with short axial length and built-in butterfly plate. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle between 0° and 90°. When it rotates to 90°, the valve is fully open.
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.
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.
