Our SD971 electric plastic butterfly valve is a combination of a monoblock electric actuator and a plastic butterfly valve. With a 220V power input, it can directly perform on/off adjustments. It can also be equipped with a servo module, allowing operation control with input control signals (4-20mADC or 1-5VDC) and single-phase power. The electric plastic butterfly valve, UPVC electric butterfly valve, and SD971S corrosion-resistant electric butterfly valve are lightweight and highly corrosion-resistant, finding applications in various industries such as potable water and drinking water pipeline systems, drainage and sewage pipeline systems, saltwater and seawater pipeline systems, and acidic, alkaline, and chemical solution systems. Their quality has been recognized by a wide range of users. The main features of the electric plastic butterfly valve, UPVC electric butterfly valve, and SD971S corrosion-resistant electric butterfly valve are as follows:
(1) The appearance and structure are compact and aesthetically pleasing.
(2) The body is lightweight and easy to install.
(3) Strong corrosion resistance, wide application range.
(4) Material is hygienic and non-toxic.
(5) Durable, easy to disassemble, and simple to maintain.
