The valve is widely used in petrochemical, oil, metallurgical and thermal power plants and other pressure pipelines, for high and medium pressure pipe even more obvious advantages. The structural design of the valve completely eliminates the pipeline medium pressure on the work of the valve so that the opening and closing pieces of media pressure is always in a self-balanced posture. The main features of the valve are as follows: 1. The operating torque of the product is only 1/10 of the traditional stop valve, without opening the valve can easily open and close the valve, not only the sealing surface of the valve is not easy to wear, and will not cause the valve Flange gasket and connecting pieces of the plastic deformation, greatly reducing the leakage, extending the service life of the flange in the flange seal, but also saves a lot of valve actuators, reducing the cost of the valve. 2. For the same specifications \ different nominal pressure of the valve, the hand wheel \ stem and packing ring and other parts of the size can be interchangeable, which not only saves material, but also for the product of serial production has created favorable conditions. The valve changes the current domestic production of only DN ≤ 100mm high pressure globe valve situation, to meet the industrial production, especially in thermal power plants, oil fields and other aspects of the larger diameter high-pressure globe valve needs. The main technical indicators of the valve are as follows: Nominal diameter DN50 & # 732; 400mm, nominal pressure PN2.5 & # 732; 32.0Mpa; Suitable media for water, steam, oil and other corrosive media; Suitable temperature ≤ 450 ℃; Operating torque (DN100mm, PN16.0Mpa as an example) 120Nm9 traditional products is 120Nm.
