Shanghai Qianhu Electric Valve Co., Ltd. has good valves. A characteristic of Qianhu Valve is its handwheel device, which is designed without a clutch. When the current is interrupted, the handwheel can be manually operated to rotate the valve to the desired position without the need for any auxiliary tools (such as wrenches, brakes, etc.). Moreover, when the power supply is normal, there will be no personal injury or driver failure caused by accidentally turning the handwheel.
