The self -force regulating valve relies on the pressure and temperature of the medium that flows through the internal valve as the automatic work of the energy -driven valve. It does not require external power supply and secondary instrument.Also known as the self -force control valve.

Self -force regulating valve brand
Brand 1: US Vegeous Dun VTON Product Name: Imported Self -Terminal Regulating Valve Product Description: American VTON Weidun is composed of valve body, valve seat, valve core parts, etc. It is a pressure that does not require external energy and only rely on the converted quality itself.Energy -saving products with automatic adjustment pressure can be used for non -corrosive stress control devices such as liquid, gas, and steam medium.Imported self -force regulating valve, control spring because it is far from the temperature of the valve, it is not easy to be affected by the temperature of the medium, and it is easier to replace or adjust the spring.Therefore, it is widely used in industrial departments such as petroleum, chemical industry, metallurgy, light industry, and urban heating and heating systems.The imported self -regulatory valve includes nominal pressure PN16, 40, 64, the nominal diameter range of 20-300mm, and the use temperature ≤350 ° C.There are a variety of varieties to choose from.There is a larger voltage range than the old type.

Self -force regulating valve work principle
After the control medium input valve, the front pressure P1 enters the lower membrane through the control pipeline, and the pressure PS input the upper membrane after the streaming valve is thrown.EssenceThe thrust between the thrust generated by the P1 on the film and the PS effect on the film and the reaction force of the spring determine the relative position of the valve core and the valve seat, thereby determining the flow of the flowing valve.When the flow of the streaming valve increases, that is, the △ PS increases, and the results of the P1 and PS are acting in the lower and the upper membranes, respectively, so that the valve core moves in the direction of the valve seat, which changes the circulation area between the valve core and the valve seat, so that the area of ??the valve seat is made, so that the area between the valve seats and the valve seat is changed to make the circulation area between the valve seat, so that the area of ??the valve seat is made, so that the area between the valve seat and the valve seat can be changed to make the circulation area between the valve seat, so that the area of ??the valve seat is made to make the area of ??the valve seat, so that the area of ??the valve seat is made, so that the area between the valve seats and the valve seats can be changed to make the circulation area between the valve seat, soIncrease PS, the thrust of the increased PS on the film plus the thrust of the spring back force with the P1 on the film to generate a balance in the new position to control the traffic.Conversely, the same.
