Main performance norm:

Use of the products:

It is suitable for nominal pressure PN20.0- 32.0Mpa and 170V of 100V-P (57 ) of P (54 ) to weld the stop valve connected, working petroleum , chemical industry , water conservancy , fire power at the of different operating modes pipeline hydropower station ,etc. of temperature ≤ 540 (P 170V working temperature among them for 570 ), cut off or put through the medium. The suitable medium is: Water , oil , steam ,etc.. The operation mode is as follows, manual, the gear wheel is transmitted, electronic etc..

Product structure characteristic:

1.The product design is made according to the regulations of E101 and JB/T3595-93 standard, the structure is rational , of good performance, handsome in appearance.
2.The sealed structure of urgent type of since one of pressures of adopting in the valve, the better the sealing property is. Prop up both ends of managing in order to weld the structure. It is can be worthy of connecting according to the standard or user's demand welding the slope mouth.
3.Valve petal , valve flat seal adopt department set up cobalt base hard alloy is it weld to pile very much, wear-resisting , is able to bear the high temperature, it is of good performance and having long performance life to resist the scotch.
4.The valve stem is through adjusting the quality and surface nitrogen treatment, there is good practising corrosivity and resisting the scotch.
5.It is rational in depth that the valve overlays the gland box , the packing adds and loses the pharmaceutical slowly, it is reliable to seal.
7.The electronic stop valve is furnished with the electronic device of DZW series valve , have small , light shells, with complete function, the characteristic such as being beautiful of appearance, and can use with the programme-controlled computer together , can be according to the electronic device of user's demand apolegamy.
