The condition of different kinds of suitable for the electric ball valve

Electric ball valve with electric actuator type switch, external regulation, switch mode can be divided into active and passive feedback, feedback, current 4 - resistance 20mA。 External regulation input and output signals: 4 - 20mA、1- 0 - 5 v 10V。 Electric 3-way ball valve pressure rating: PN1. 6 - PN4. 0 mpa is generally used in medium reversing, shunt, confluence, mixed flow, temperature according to the valve body and seat material definition. Hard seal electric ball valve pressure rating: PN1. 6 - PN4. 0 mpa, metal sealing seat, characteristics of high temperature resistant, high temperature conditions chosen commonly. Three type electric ball valve pressure rating: PN1. 6 - PN6. 3 mpa, compressive ability strong, tear open outfit is convenient, use specific see seat valve core material temperature. Plastic electric ball valve pressure rating: PN1. 0 - PN1。 6 mpa, small size light weight, corrosion resistance is strong, suitable for acid and alkali corrosive medium. Electric V type ball valve pressure rating: PN1. 6 - PN4. 0 mpa, V type ball valve core, have the function of the flow rate, and shear force and self-cleaning ability. Suitable for medium with fibrous or small particles. Electric high pressure ball valve pressure rating: PN10. 0 - PN50. 0 mpa, feature resistance to high pressure valve, forged valve body, the cost is high, suitable for high pressure air, liquid, oil, etc.
