Why are sealing devices required for gate valves and globe valves?

Gate valves and globe valves are required to have upper sealing devices, mainly based on the following considerations: 1. Prevention of medium leakage and protection of packing Prevent medium leakage: When gate valves and globe valves are in the closed state, the valve stems remain at rest. If there is no upper sealing device, the medium may seep upward along the gap between the valve stem and the valve body, causing the medium to leak out. The upper sealing device can effectively prevent the leakage of the medium and ensure the working performance and safety of the valve.

Is there any difference between an electric valve and an electric actuator?

The differences between electric valves and electric actuators: 1. Different driving energy sources 2. Different cut-off mechanisms electric valve, English name :motor-driven valve or Electric Valve. An electric valve, simply put, is a valve controlled by an electric actuator to achieve the opening and closing of the valve. It can be divided into two parts, the upper part being the ele
