Product Description

   Globe valve, due to the opening and closing process between the sealing surface friction is small, more durable, opening height is not only suitable for low and medium pressure, but also suitable for high pressure. The closing principle of the globe valve is to rely on the valve bar pressure, so that the valve disc sealing surface and seat sealing surface closely fit, prevent the flow of media. Advantages: 1. Simple structure and convenient maintenance.

2, small working trip, short opening and closing time.

3, good sealing, sealing surface friction between small, long life.

4. The structure of the globe valve body is straight-through, straight-flow and right-angle. The straight through is the most common structure, but its fluid has the greatest resistance. Straight flow fluid has less resistance and is mostly used for fluid containing solid particles or high viscosity. Right-angle valve body is forged, suitable for small pass, high pressure globe valve.

5. In the process of opening and closing, the friction of the sealing surface is smaller than that of the gate valve, and it is wear-resistant.

6, usually only one sealing surface, good manufacturing process, easy to maintain. 1, high temperature, high pressure medium pipeline or device should be selected cut-off valve. Such as thermal power plant, nuclear power plant, petrochemical system of high temperature, high pressure pipeline.

2, the pipeline resistance is not strict requirements of the pipeline. Where there is little consideration of pressure loss.

3. There is flow regulation or pressure regulation, but the requirement for regulating accuracy is not high, and the diameter of the pipeline is relatively small, such as the pipe with nominal passage ≤50mm, it is appropriate to choose.

4, synthetic industrial production of small chemical fertilizer and large chemical fertilizer should be selected nominal pressure PN160 nominal pressure 16MPa or PN320 nominal pressure 32MPa high pressure Angle globe valve or high pressure Angle throttle valve.

5, alumina Bayer process in the production of desilicon workshop, easy to coking pipeline, easy to choose the valve body separate type, seat can be removed, hard alloy sealing pair of straight flow globe valve or straight flow throttle.

6, in the city construction of water supply, heating engineering, the nominal pass smaller pipeline, can choose cut-off, balance valve or plunger valve, such as the nominal pass less than 150mm pipeline.
