Characteristic
Basic information
Applicable to the pipeline pressure, strict requirements for sealingand cutting process switch occasions medium pipe and fluidcontrol system.
Operating temperature: -20 ℃ to +150 ℃ (+250 ℃ special seal).
Range
Air, steam, water, gas, oil and petrochemical products, corrosive medium.
Electric ball valve and valve; Shanghai, V type ball valve is a coreseat with metal, rotating ball valve or metal to PTFE sealing, thebest control characteristics of electric ball valve ball valve and butterfly valve are combined into a whole, can be used as acontrol valve, and also can be used as a cut-off valve. Its main feature is the:
(1) The whole body without any pipe joint, and therefore not subject to pipeline or bolt stress influence, and because the valve body without any pipe joints, so the pressure hull are not affected by the pressure of "mutation";
(2) The electric ball valve has a V type valve, even in small flow rate or high viscosity media, also can be in the range, accuracycontrol;
(3) The electric ball valve leak proof and durable seat in outer diameter lined with stainless steel inner core PTFE cup or O type sealing ring, valve seat made of tungsten carbide cobalt larger section, through a corrugated spring alloy further enhances theseat structure;
(4) When the valve is closed, the wedge-shaped shearing type Vgap and the electric ball valve and valve seat, and not only has the function of self-cleaning and can prevent the ball core lock,electric ball valve is especially suitable for the freezing pipeline or containing fibers and particles of solid.
Job characteristics
Operating temperature: -20 ℃ to +150 ℃ (+250 ℃ special seal).
Working pressure: PN16, PN25 - PN40 - PN64 -PN100
Fluid range
Air, steam, water, gas, oil and petrochemical products, corrosion resistance, acid and alkali medium if.
