Forged A105 globe valve through the valve body inside the valve flap to realize the control of the medium, when the handle or transmission device rotates, the valve flap and the sealing surface between the valve seat to produce contact, preventing the flow of media. On the contrary, when the handle or transmission device is rotated again, the valve flap and the valve seat are separated and the medium starts to flow. By controlling the angle of rotation of the handle or transmission device, you can adjust the flow size of the medium. With simple structure, good sealing, high temperature and high pressure resistance, etc., is widely used in petrochemical, electric power, metallurgy and other fields.

Forged globe valve
Forged steel globe valve attention to the valve in the switch position. Ball valve maintenance are generally in the open position, special circumstances choose to close the maintenance. Other valves can not be generalized to the open position. Forged steel globe valve in the maintenance must be in the closed state, to ensure that the grease along the seal ring is full of sealing grooves, if the open position, the sealing grease is directly into the flow path or valve cavity, resulting in waste. Valve grease injection, often ignoring the effect of grease injection. Grease injection operation pressure, grease injection volume, switch position are normal. However, in order to ensure the effect of valve greasing, it is sometimes necessary to open or close the valve to check the lubrication effect, to confirm that the valve ball or gate surface lubrication is uniform.
