Product Features
1. When the system works normally, the gate opens and closes at a constant speed of 1.0 m / min, while the closing in case of power failure can be divided into two stages: fast closing and slow closing. 100-20% opening is fast closing, time 10 (s). 20-0% opening is slow closing, and the time is 40 (s).
2. It is used as a stop and check valve at the water pump outlet, and the valve also has a valve rod locking device. Ensure safe operation.
3. The new electric device can be operated locally or remotely, and can meet the requirements of computer program control. The control is accurate, safe and reliable.
