Vacuum valve selection guide
Vacuum valve is used in the vacuum system used to cut or connect or adjust the airflow actuators.
Ⅰ. According to their characteristics are as follows:
Structural features: Flapper Valve (Globe Valve), angle valve, diaphragm valves, aseptic compartment valve, flap valve, flapper valve, butterfly valves, pneumatic solenoid valve (vacuum valve), electromagnetic Flapper Valve (Globe Valve , inflatable valve), valve, fine-tune the valve, check valve, angle seat valve (45 °), super-pressure relief valve, plunger valve, pneumatic valve (pneumatic overpressure bypass discharge flow valve)
Working pressure: low vacuum, high vacuum, ultra-high vacuum
Drive mode: manual, flashlight with two, pneumatic, electromagnetic, hydraulic
Usage: closed, connected, flow regulation, inflation, health, change to
Material: aluminum alloy, carbon steel, stainless steel, PTFE
Ⅱ. All kinds of vacuum valves Applications:
Flapper Valve Applications: vacuum diffusion unit as the main valve, pre-pumping valves; vacuum metallurgy system; vacuum exhaust system; space simulation, electronics, semiconductor and other industries; generally low, high-vacuum system applications.
Valve Applications: vacuum freeze-drying equipment, as box valves, water catching device valve; vacuum metallurgy system; vacuum exhaust system; general vacuum unit, high-vacuum system applications.
Valve Applications: vacuum freeze-drying, vacuum fresh-keeping equipment applications; medicine, food systems;; generally low, high-vacuum system applications.
Vacuum Flashboard valve: design novel, seal with welded bellows seal, vacuum high performance and reliable; fluoro-rubber ring seal forms the connection flashboard valve is mainly used in the general high-vacuum system. The form of metal seal connection flashboard valve is mainly used in ultra-high vacuum system. Applications: Aerospace ultra-high vacuum simulation accelerator system; vacuum metallurgy, semiconductors, and other industries.
Vacuum Diaphragm Valve: suitable rust lithium working fluid cooling unit of special conditions; higher operating temperature; a corrosive and long working system environment.
Ⅲ. Vacuum valves, vacuum the basic requirements of product assembly, connection methods, components, assembly, final assembly of the technical requirements such as reference standard:
Connection standard: GB/6070/JB919/GB4982-85;
Vacuum Valves Technical Article: JB6446-92;
"O"-ring rubber sealing ring vacuum form and size: JB1092-91;
General technical requirements of pneumatic system: GB7932.
