US-10 2W040-10 3/8'' Direct Acting Flow Control Solenoid Valve
This valve is N/C (normally closed), meaning it is closed when power isn't supplied.
2W040-10 Normal Closed (N/C) Solenoid Valve Is Constructed With Brass Body Which is high reliability, long service life and low cost.;standard seal material defaults to Nitrile rubber,suitable for a variety of working media.
Widely Used In industry Flow Control, Liquid Control and Gas Contol.
Suitable for use with water, gas, air, very low viscosity fluids (< 20 cst)
This 220V AC brass electric solenoid valve easily replaces broken valves for use. This unit fits a 3/8" thread.

Installation Direct-acting Solenoid Valve:
1.Before using the solenoid valve for water, pay attention to the product label and read the instruction manual carefully to judge whether the product meets the conditions of use.
2.In order to avoid orifice obstruction, it is recommended to install a pre-filter.
3.There is an arrow indicating the direction of flow on the stainless valve body. Coil up is the preferred mounting direction but if necessary it can be installed in any position.
4.Stainless steel is present as the internal components and Viton as the seal material.
5.This Solenoid Valve is unidirectional .The installation should follow the instructions of “→”.
6.The Body Material is Brass. The Seal Material is NBR,EPDM or VITON.
7. When the solenoid valve is faulty, in order to isolate the solenoid valve in time and ensure the normal operation of the system, it is better to install a bypass device.
According to the fluid parameters choose solenoid valve
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.
