How to open and close the electric gate valve? Switch tips not to be missed! The closing time of the electric head of the electric gate valve does not exceed 30S. What is the impact of the open closing time? The switching time of the electric gate valve?   Twist it to the left to close, and twist it to the right to open the valve. Pay attention to the arrow mark on the valve. The electric head switching time of the electric gate valve is determined by the speed, pitch, and molding method according to user requirements; under the same torque requirements, the faster the rotation speed, the shorter the molding time, the larger the pitch, the shorter the opening and closing time, the greater the power, and the natural price. The more expensive.

  How to open and close the electric gate valve? Switch tips not to be missed! The closing time of the electric head of the electric gate valve does not exceed 30S. What is the impact of the open closing time? The switching time of the electric gate valve?

  Twist it to the left to close, and twist it to the right to open the valve. Pay attention to the arrow mark on the valve. The electric head switching time of the electric gate valve is determined by the speed, pitch, and molding method according to user requirements; under the same torque requirements, the faster the rotation speed, the shorter the molding time, the larger the pitch, the shorter the opening and closing time, the greater the power, and the natural price. The more expensive.

  If the customer has no requirements for the switching time of the electric gate valve , we can find a low-speed, low-power, and cheap solenoid head that meets the torque requirements. By the way, let me share with you some tips on the installation and daily maintenance of electric gate valves!

 

      Installation method of electric gate valve

 

 

  (1) Before installing the electric gate valve , you should carefully check whether the model and specifications of the valve used are consistent with the design;

  (2) According to the valve model and factory instructions, check whether the valve can be used under the required conditions;

  (3) When lifting the valve, the wire rope should be tied to the flange connection between the valve body and the valve cover, and should not be tied to the handwheel or valve stem to avoid damage to the valve stem and handwheel;

  (4) When installing the valve on a horizontal pipeline, the valve stem should be vertically upward and it is not allowed to install the valve stem downward;

  (5) When installing the valve, the forced port connection method of pulling is not allowed to avoid damage caused by uneven stress;

  (6) The open stem gate valve should not be installed in a humid place underground to prevent the valve stem from rusting.

 

  Daily maintenance methods for electric gate valves

 

  (1) The valve should be stored in a dry and ventilated room, and both ends of the channel should be blocked.

  (2) Valves stored for a long time should be inspected regularly, dirt should be removed, and anti-rust oil should be applied to the processed surface.

  (3) Regular inspections should be made after installation. Main inspection items:

  A. The sealing surface is worn.

  B. The trapezoidal thread of the valve stem and valve stem nut is worn.

  C. Whether the packaging has expired and is invalid. If it is damaged, it should be replaced in time.

  D. The sealing performance test should be carried out after valve repair and assembly.
