HTF HTF electric three-way valve principle electric three-way valve with double spool down oriented structure, equipped with electric actuator mechanism, the body of the three-way structure, that one into two (split type), two into one out (confluence type), so as to achieve fluid mixing heating or cooling, or a different amount of fluid shunt, to meet the requirements of different mining. The valve body has a compact, light weight, sensitive, small pressure loss, valve capacity, flow characteristics of precision and easy maintenance. Can be used for a variety of working conditions, especially for the oil temperature control system of industrial heat exchangers and other industry automation and control systems. Hayward proportion of electric three-way valve type products at room temperature, high temperature, low temperature, adjust the cut-off, bellows seal type and other types. Nominal grade products have PN1.6,4.0 6.4; body diameter range of DN20-DN300; applicable fluid temperature -150 ℃ - + a variety of grades in the range of 560 ℃; leak into atmosphere Ⅳ grade level, Ⅴ grade, Ⅵ level; Flow characteristics are linear, equal percentage. A variety of specifications to choose from. Second, the valve member stem material: stainless steel or alloy steel, or other special treatment as required. Spool Material: Stainless steel or as needed Stellite alloy welding, or other special treatment as needed. Seat Material: Stainless steel or as needed surfacing Stellite alloy, or other special treatment as needed. Third, the proportion of electric three-way valve structure is a rotary type valve off valve has closed tight, compact, and easy maintenance. Electric three-way valve with T-L sub-type, T-type three-way links can communicate with each other perpendicular to the pipe, that is, from the shunt (confluence) effect, which can also cut the other two pipelines and a pipeline connectivity; L Three-way communication with each other only two orthogonal pipe or switching direction, that is, from a distribution function. Two-way ball valve seat seal can be achieved in the pipeline medium flow switch. Also enables two mutually perpendicular passage or closed. Four way ball valve seat sealing medium flow switching can be achieved, but also allows three interconnected channels, flexible control line merge and split media types.
