quick opening and quick closing valve 

    Hydraulic Quick Closing Valve refers to valve-type switches, such as faucets, pressure cooker valves, etc., which play a role in cutting off. On-off valve is divided into Pneumatic Quick Closing Valve and electric on-off valve.     The Marine Quick Closing Valve is an adjustment and prevention device. When we find that the ship is in danger and the air pressure is too low, it can be quickly closed to ensure the safety of the ship. The reason why it has the unique name of the fast closing valve is because its requirement is that the closing speed must be fast. Only in this way can the ship be guaranteed to be in a safe state at all times. If the closing speed is slow, it may cause some danger. Under normal circumstances, its closing time can be completed within 0.5 seconds.
