NBR VITON Seal Normally Closed 1 1/2'' SUW-40 2S400-40 Uni-D Type Solenoid Diaphragm Valve 24V DC 220V AC


2S, SUS & SUW series stainless steel solenoid valves are devices that regulate fluid or air flow. Due to their durability and reliability, these devices are ideal for various industrial applications. They are used in the control of water, air, inert gases, steam, and of fluids in general that have different levels of aggressiveness. They are employed in various sectors, for both domestic and industrial use and are used for household appliances and coffee machines, drinks machines, industrial washing machines, autoclaves/sterilizers, irrigation systems and fire suppression, dental equipment, steam boilers and industrial applications.

Troubleshooting of common problems in solenoid valve:


Problem 1: The Valve makes noise

Reason 1: AC coils may have a slight hum do to cycle cycling. If top nut is lose, tightening it may reduce the noise.
Reason 2: Dirt or wear in the armature may cause a humming noise. Clean Armature tube.
Reasoon 3: LOUD BUZZING. If your solenoid valve is buzzing loudly immediately disconnect the valve. This may be caused by incorrect voltage or power supply and can cause serious bodily harm or system damage if not corrected.

Problem 2: The valve gets extremley hot or emits smoke.

Reason 1: The solenoid valve will become warm or uncomfortably hot to the touch. This is typically normal as it is dissipating heat.
Reason 2: If your solenoid valve is extremely hot or emitting smoke immediately disconnect the valve. This may be caused by incorrect voltage or power supply and can cause serious bodily harm or system damage if not corrected.

Problem 3: Nothing happens when I connect power

Reason 1: Make sure there is a proper electrical connection (voltage, current, frequency). Use a multimeter to test all components.
Reason 2: The coil is disconnected or burned out. Check your wiring to the coil and confirm the valve is receiving the correct specifications. OHMs can be checked to determine if the coil has burned out.
