                      What are the classification of stainless steel cut-off valve products?

                      Date:[2017-05-20]     Hits:

                      Stainless steel cut-off valve products are classified? Stainless steel globe valve is widely used in chemical, shipbuilding, medicine, food machinery and other industries. Products have been born so far, was used in a number of industries, product development and social progress is closely related. Product performance in the development of science and technology is also driven by continuous improvement, therefore, the frequency is used is also very high. In order to use the product more in the future more at ease when the purchase of the need to choose the regular manufacturers, and in the operation must also follow the instructions in the instructions!

                      Stop valve holding point:

                      (1) structure than the gate valve is simple, manufacturing and maintenance are more convenient.

                      (2) sealing surface is not easy to wear and abrasion, sealing is good, open and close when the valve disc and the valve sealing surface between no relative sliding, and thus wear and scratches are not serious, good sealing performance, long service life.

                      (3) opening and closing, the valve flap stroke is small, so the valve height is smaller than the gate valve, but the length of the structure longer than the gate valve.

                      (4) opening and closing torque, opening and closing more laborious, opening and closing time principals.

                      (5) fluid resistance, because the valve body channel is more tortuous, fluid resistance, power consumption.

                      (6) the flow direction of the media nominal pressure PN ≤ 16MPa, the general use of downstream, the medium from the valve down the flow; nominal pressure PN ≥ 20MPa, the general use of countercurrent, the media from the valve up the flow to increase the seal The When used, the stop valve medium can only flow in one direction, can not change the direction of flow.

                      (7) When the valve is fully open, it is often eroded.
