Product Description:
Product structure and principle related attributes
Pilot mode: There are internal or external guidance options
available, which can be selected according to actual application
scenarios and needs.
Action modes: Mainly including direct action and pilot action. The
direct acting type relies on electromagnetic force to directly
drive the valve core action, with a simple structure and no need
for medium pressure assistance. It is suitable for low flow and low
pressure drop scenarios and has a fast response speed; The pilot
type uses the pilot air path to control the action of the main
valve core, requiring a certain medium pressure difference to work,
suitable for high flow and high pressure difference scenarios, with
low power consumption.
Sliding column structure: Good sealing, sensitive response, able to
quickly and accurately achieve the on/off and switching of gas
paths.
Number of valve positions: There are various types such as two
position three-way, two position five way, and three position five
way to meet different pneumatic control circuit requirements.
Memory function: The dual head two position solenoid valve has a
memory function, which can maintain the previous state after power
failure, helping the system to operate stably.
Product performance related attributes
Working pressure range: Generally 0.15-0.8MPa, different models may
vary, and can adapt to various pneumatic systems with different
pressure requirements.
Temperature range: Usually -20 ℃ to 70 ℃, special models support a
wider range and can work normally at different ambient
temperatures.
Response time: Short, usually in milliseconds, can quickly switch
gas paths and improve system efficiency.
Switching frequency: High, able to meet the working requirements of
frequent actions, suitable for fast cycling pneumatic control
processes.
Power consumption: Low power design, energy-saving and reducing
heat generation, helps to reduce system operating costs and improve
safety.
Product material and specification related attributes
Valve body material: Made of aluminum alloy or stainless steel, it
has strong corrosion resistance and can adapt to different working
environments, such as humid, acidic and alkaline corrosive
environments.
Sealing material: Mostly NBR (nitrile rubber) or FKM
(fluororubber), can adapt to different media such as air, inert
gases, etc., ensuring good sealing performance.
Nominal diameter: Common sizes include DN50mm - DN300mm (NPS2-12),
as well as interface sizes such as 1/8 ", 1/4", and 3/8 ", which
can meet different flow requirements and pipeline connection
requirements.
Voltage: Multiple standard voltage levels such as DC12V/24V,
AC110V/220V are available for selection, making it convenient to
match with different electrical control systems.
Product features and application related attributes
Function type: There are normally open (NO), normally closed (NC),
bidirectional control, etc., and the appropriate function type can
be selected according to specific control requirements.
Application areas: Widely used in industries such as packaging,
papermaking, printing, electrical, biotechnology, petroleum,
energy, electronics/batteries, as well as pneumatic control
circuits in automation control systems.
Product protection related attributes: The standard product
protection level reaches IP65, dustproof and waterproof, suitable
for harsh industrial environments, can effectively protect the
internal components of the solenoid valve from external dust and
moisture erosion, and improve the reliability and service life of
the product.
Technical Parameters:
Multiple Control Modes
- Normally Closed/Normally Open Types: The valve port is closed or open in the default state, suitable
for scenarios requiring a safe initial state (such as emergency
shutdown or automatic air supply).
- Bidirectional Control Type (e.g., 2-position 5-way or 3-position 5-way valves): Supports
bidirectional air flow switching, used to drive cylinder
reciprocating motion (such as the extension and retraction of
mechanical arms or the start and stop of conveyor belts).
- Memory Function Type: Maintains the valve position after power failure to prevent
system out-of-control due to power loss (such as process
maintenance in continuous production lines).
Flow and Pressure Regulation
- Wide Range of Nominal Diameters: From small calibers (e.g., G1/8") to large sizes (e.g., DN50mm),
adapting to different flow requirements (small flow for precision
instruments, large flow for industrial equipment).
- Broad Pressure Range: The working pressure typically ranges from 0.15 to 0.8MPa,
compatible with low-pressure pneumatic systems (such as automated
production lines) and medium-to-high-pressure scenarios (such as
construction machinery and heavy equipment).
