NUMATICSsolenoid valveAutomotive 75, 125, 250 Series Valves75，125，250Series of automotive valves

The Numatics 75, 125, and 250 Automotive Series valves comply with automotive interchangeable and SAE industrial standards.In Newman's Ark75，125and250The series of valves comply with the interchangeability between the automotive and automotive industriesSAEStandard.These are high speed, heavy duty valves designed for general service on all types of automation.This is a high-speed, heavy-duty general service designed to automate all types of valves.Manifold or base mounted.Manifold or base expansion.

The selection of solenoid valves should first follow the four principles of safety, reliability, applicability, and economy in sequence Then, the selection is based on six aspects of on-site working conditions, namely pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action mode, and special requirements.

Selection criteria:

1Select solenoid valve based on pipeline parameters: diameterspecification(i.eDN）Interface method

1）Determine the diameter according to the on-site pipeline inner diameter size or flow requirements（DN）Size;

2）Interface method, generally>DN50to chooseflange interface，≤DN50Users can freely choose according to their needs.

2Select solenoid valve based on fluid parameters: material, temperature group

1）Corrosive fluid: It is recommended to use corrosion-resistant solenoid valves and fullstainless steelEating ultra clean fluids: it is advisable to chooseFood grade stainless steelMaterial solenoid valve;

2）High temperature fluid: Choose electromagnetic valves made of high-temperature resistant electrical and sealing materials, and choose piston type valvesstructural typeof

3）fluid stateLarge to gaseous, liquid or mixed state, especially with a diameter greater thanDN25It is necessary to distinguish between them;

4）Fluid viscosity: usually within50cStYou can choose any of the following. If it exceeds this value, a high viscosity solenoid valve should be selected.

3Selecting solenoid valves based on pressure parameters: principles and structural types

1）Nominal pressure: This parameter has the same meaning as other general valves and is determined based on the nominal pressure of the pipeline;

2）Work pressure: If the work pressure is low, the principle of direct action or step-by-step direct action must be selected; The work pressure difference is0.04MpaThe above options include direct acting, step-by-step direct acting, and pilot operated.

4Electrical selection: Voltage specifications should be prioritized as much as possibleAC220VTheDC24More convenient.

5Choose based on the duration of continuous work: normally closed, normally open, or continuously powered on

1）When the solenoid valve needs to be opened for a long time and the duration is longer than the closing time, it should be selected Use normally open type;

2）If the opening time is short or the opening and closing time is not long, choose the normally closed type;

3）However, for some working conditions used for safety protection, such as furnace and kiln flame monitoring, the normally open type cannot be selected, and the long-term electrified type should be selected.

6Select auxiliary functions according to environmental requirements: explosion-proof, check, manual, waterproof fog, water shower, diving.
