2/2 Way Normally Closed Direct Drive Aluminum Body 2S400-40 1-1/2" Stainless

Product Specification

2/2 Way Normally Closed Direct Drive Aluminum Body 2S400-40 1-1/2'' Stainless Steel Solenoid Diaphragm Valve

2way of general purpose of direct action and semi-direct elevator valves of action.

Common applications include water, oil (below 20cst), air, gas, freon, * vacuum, weak alkaloid acids.

available on a body/seal material of bronze/NBR or stainless steel/viton.

the coil has an adapter with screw terminals for conducting wires.

simple connect the wires to the adapter and connect right into the coil for operation.

adapters can be removed from the coil for maintenance without having to remove the wires.

bronze/NBR valves ar e suitable for water, hot water, gas, air, non-corrosive oils and freon.

Stainless steel/Viton valves are suitable for hot water, acid, alkaline, chemical salt, oils and hydrocarbons.

Direct action: These valves close or open completely on their own.

That means they can block the flow of fluid in both directions.

semidirect Actions: These valves can only stop the flow in one direction.

There is an arrow located in the valve body showing the direction of the flow in which it blocks.

in order to avoid reflux when the valve is closed, a restraint valve shall be installed

Feature:

Adopting straight-action without pressure starting enlarges its applicable scopes.
Adopting plate diaphragm structure with reliable start and close lengthens the service life of the product.
Selecting encapsuled coil improves the safe application of this product under many environments.

1.Brass Body,Strong corrosion resistance and beautiful appearance

2.Copper Coil,Tightly wounded, full of weight

3.At the wire joint, it is further processed and safer and more reliable.

4.Spring diaphragm for durability and aging resistance

Selection basis:

First,Select the diameter specification (ie DN) and interface mode of the solenoid valve according to the pipeline parameters.

1.Determine the diameter (DN) size according to the inner diameter of the pipeline or the flow requirement.

2.interface mode, general > DN50 to choose the flange interface, ≤ DN50 can be freely selected according to user needs.

Second,Select the material and temperature group of the solenoid valve according to the fluid parameters

1.corrosive fluid: should choose corrosion-resistant solenoid valve and all stainless steel; edible ultra-clean fluid: food grade stainless steel solenoid valve should be used.

2.high temperature fluid: to choose the use of high temperature resistant electrical materials and sealing materials made of solenoid valves, and to choose the type of piston structure.

3.the fluid state: large to have a gaseous state, liquid or mixed state, especially when the caliber is larger than DN25 when ordering must be distinguished.

4.fluid viscosity: usually below 20cSt can be arbitrarily selected, if the viscosity is high, you should use high viscosity solenoid valve.

Third,Select the principle and structure of the solenoid valve according to the pressure parameters

1.Nominal pressure: This parameter has the same meaning as other general-purpose valves and is determined according to the nominal pressure of the pipeline.

2.Working pressure: If the working pressure is low, the direct-acting or step-by-step direct-acting principle must be used; when the minimum working pressure difference is above 0.04Mpa, direct-acting, step-by-step direct-acting or pilot-operated can be used.

Fouth,Voltage selection: The voltage specification should be as convenient as possible for AC220V and DC24.

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