1、 Product Overview
Electric switch ball valveIt refers to a valve in which the opening and closing member (i.e. ball) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. It is a rotary ball valve with a 90 ° angle, consisting of angular stroke electric actuators (DSR, PSQ, HQ, DZW) and a ball valve body.Ball ValveSuitable for situations where two positions are cut off and adjusted, it adopts an integrated structure with an electric actuator built-in servo system, without the need for additional servo amplifiers. It can control operation by inputting 4-20mA control signals or 1-5VDC and 220VAC power supplies.Electric switch ball valveIt has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable action. This electric switch ball valve is particularly suitable for applications where the medium is viscous, contains particles, and has fiber properties. Currently, it is widely used in various fields such as petroleum, chemical, metallurgical, light industry, papermaking, power plants, refrigeration, etc.
