What's the material of j41h-16p's valve?
According to the provisions of the JB/T 308-2004 valve type programming method:J== stop valve4== flange type1== through channelH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaP== body material: chrome nickel stainless steel. As of 304
Stop valve characteristics:(1) the structure is simpler than the gate valve, and the manufacture and maintenance are more convenient.(2) the sealing surface is not easy to wear and scrape, good sealing, when opening and closing, there is no relative sliding between the valve and the sealing surface of the valve body, so the abrasion and abrasion are not serious, the sealing performance is good, and the service life is long.(3) when opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the structure length is longer than the gate valve.(4) the opening and closing moment is big and the opening and closing are more strenuous.(5) large fluid resistance, due to the valve in the medium channel is tortuous, large fluid resistance, power consumption.(6) the flow direction of medium nominal pressure PN is less than or equal to 16MPa, commonly used downstream, medium from the valve under the direction of flow; nominal pressure PN = 20MPa, using reflux, medium from the valve on the downstream direction to increase the seal. When used, the cut-off valve medium can only flow in one direction, can not change the direction of flow.(7) when fully open, the disc is always subject to erosion.
The j41h-16p valve is a stainless steel globe valve.The working principle of stop valve:The cut-off valve, also called the door, is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure.The closing principle of the valve is to rely on the valve bar pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the circulation of media.The one-way valve can only medium flow direction when installing. The structure length of the stop valve is larger than that of the gate valve, and the fluid resistance is large, and the reliability of the sealing is not strong during the long-term operation.
J41H-16P is: manual stainless steel flange, hard sealing stop valve, pressure 1.6MPa. Material: 304.
