Types of Solenoid Valve Series

 

The solenoid valve series produced by our company mainly include the following types:

Micro Solenoid Air Valve

Micro solenoid air valve supports flexible customization of voltage and resistance parameters. Its valve body undergoes a precision blue zinc plating process to form a protective layer, featuring excellent corrosion resistance.

Micro Water Valve

Micro water valve supports flexible customization of voltage and resistance. Its valve body undergoes multi-layer precision blue zinc plating, forming a dense protective layer-boasting excellent corrosion resistance and wear resistance, which enables it to remain intact under harsh conditions.

Advantages of Solenoid Valve Series
 

The external leakage can be completely blocked and the internal leakage can also be easily controlled, so as to ensure the safe in the use.
Internal and external leakage is an essential element of safety. Other automatic control valves usually extend the valve stem and control the spool rotation or movement by an electric, pneumatic, hydraulic actuator.

 

The operation is simple, conveniently connected to the computer, and the price is low.
The solenoid valve has simple structure and low price, and it is easy to install and maintain compared to other types of actuators such as regulating valves. What's more, the auto-control system formed by solenoid valve is much simpler and the price is much lower.

 

Fast response time, small power consumption, and light weight.
The solenoid valve response time can be as short as a few milliseconds, even a pilot operated solenoid valve can be responded in tens of milliseconds. Because of the self-contained loop, it is more sensitive than other automatic control valves.

 

The function is simple and easy to use.
Solenoid valves usually only have two states of switching, on and off, and it is easy to install and use in the pratical applications. However, the valve core can only be in two limit positions and can not be continuously adjusted, so the accuracy of adjustment is also limited.

 

Various models, and wide applications

Although there are some insufficiencies, the advantages of solenoid valves are still very outstanding. So it is designed into all kinds of products to meet different needs. The solenoid valves are widely used in wide range of applications.

Step-by-step Process to Replace a Solenoid Valve
 

Turn Off the Water Supply
Shut off the water supply to the affected zone or the entire irrigation system.

 

Turn Off Power
Turn off the electrical power to the system where the valve is located. Work in a dry environment to avoid any electrical hazards.

 

Locate the Solenoid Valve
Find the location of the faulty solenoid valve in the system. Run a manual test from the controller to determine which valve needs replacement, or you can look for malfunctioning signs such as leakage.

 

Disconnect the Wiring
Carefully disconnect the wiring connected to the solenoid.

Remove the Old Valve
Use a wrench to unscrew the old solenoid valve from the valve body by turning it counterclockwise. If the valve is threaded into tubing, use a pipe wrench or adjustable pliers to remove it.

 

Install the New Solenoid Valve
Insert the new valve into the pipe. Double-check that the new valve is in the correct position and direction. Arrows on the valve body indicate the water flow.

 

Reconnect the Wiring
Reconnect the electrical wires from the valve to the irrigation controller using wire connectors for a secure connection.

 

Test the New Solenoid Valve
Turn the water supply on and restore the power to test the valve. Manually run the irrigation system to confirm the new valve is working correctly. Check connections for leaks. If there are any, tighten the connections.

FAQ

 

 

Q: What is the common problem of solenoid valves?

A: Common causes of solenoid valve failure include incorrect voltage, liquid contact, sediment damage, excess water pressure, and temperature changes, making troubleshooting methods essential to mitigate these issues.

Q: How do I know what solenoid valve I need?

A: Principle of operation.
Circuit function.
Pipe diameter and thread type.
Orifice, Kv-value and flow rate.
Medium (defines the choice of valve materials)
Pressure.
Temperature.
Response time.

Q: How do I test a solenoid valve?

A: To test a solenoid valve, use a multimeter to check the coil resistance and ensure it's within the manufacturer's specified range. You should also apply the correct voltage to the coil to listen for a distinct click, indicating movement of the plunger. A proper functional test involves applying pressure or vacuum to the valve while energized to see if it opens or closes as intended.

Q: Can you manually open a solenoid valve?

A: One way is to simply turn the solenoid (the black cylinder with 2 wires) counter-clockwise a 1/4 to 1/2 turn. To shut off the valve, twist the solenoid clockwise until it is snug on the valve. The other way is to use the bleed screw the same way, loosen the screw enough to release air (1/4 to 1/2 turn).

Q: How to tell if a solenoid valve is normally open or closed?

A: To determine if a solenoid valve is normally open or closed, check its marking or label; a "NO" or "NC" stamp indicates its default state, while a visual inspection for a flush locknut (normally closed) or grooved lines (normally open) can also provide clues for some valve types, and an "T" symbol with an arrow in the unactuated state on a diagram or the valve itself indicates a normally closed valve, while the opposite indicates a normally open one.

Q: What is the lifespan of a solenoid valve?

A: The lifespan of a solenoid valve depends on several factors, including the quality of the valve, the nature of the fluid or gas it controls, operating conditions, and maintenance practices. Generally, a well-maintained solenoid valve can last anywhere from 1 to 10 years.
