There are different designs available for a solenoid valve but the functions for all are primarily similar. A solenoid valve is designed to hold or regulate the water flow and pressure in the line.

For landscaping and irrigation projects, the search for an expert solenoid valve supplier is prioritized. However, finding expert suppliers isn’t that easy.

You need to have basic knowledge related to solenoid valves. In this guide, you will get the details of all things essential about solenoid valves and make the right choice.

Components of a Solenoid Valve


A majority of solenoid valves are serviceable. This means that the valve components can be repaired, cleaned and maintained easily.
There are mainly three components in a solenoid valve and they are -

Body - The body of a solenoid valve can either be metallic or plastic. For example, a 2 way plastic solenoid valve for sports turf irrigation.
Some of the valves can also come with a serviceable top that allows for rapid access to the diaphragm.

Coil - The coil is the second component of a solenoid valve and is generally detachable. It wires to the controller. 
The coils are usually magnetic charged springs that open or shut upon delivery of power. This action also results in the opening and closing of the upper chamber outlet. 
With this action, the internal pressure can be regulated effectively.

Diaphragm - It is the physical component that opens or closes permitting water flow. Upon filling the upper chamber, the pressure works to keep the diaphragm shut. 
When the pressure balances, it causes the diaphragm to lift allowing water to flow.

Why are Solenoid Valves suitable for Irrigation & Landscape systems?

Solenoid valves are capable of withstanding open flow and pressures. Therefore, making them a suitable choice for landscape and irrigation systems. 

A Globe solenoid valve for agriculture and horticulture is typically rated 12-16 Bar. Even a standard solenoid valve for landscape applications is rated the same. 

This allows operators to directly connect the valve to the mains water supply or directly after a pump. Solenoid valves also deliver the performance of minimal flow restriction. 

Additionally, the average lifespan of solenoid valves ranges from 10 to 30 years. All of these factors make solenoid valves fitting for irrigation and landscape systems.

Parameters to Consider for Solenoid Valve Selection

  • Solenoid valves are dirt-sensitive which means they operate only with clean liquids. But there is more to solenoid valves than this specific detail.
  • For the most optimized performance from a solenoid, you are required to consider a few key parameters.
  • Whether it is brass solenoid valve for sports turf irrigation or solenoid valve for landscape irrigation, these are important factors to consider.


Operation Principle - There are different types of solenoid valves available supporting different principles of operation. This is why it is important to consider the right principle of operation.
Direct operated solenoid valves work from 0 bar. This principle of operation is seen in small solenoid valves with small flow rate capacity.
For solenoid valves with larger flow rate capacity, you must consider indirect or semi-direct principles of operation.

Pressure - Another key consideration is the operating pressure of the system. If the specified maximum pressure goes over then the solenoid valve may burst or damage.
The maximum pressure is in relation to the type of medium. Be sure to confirm the pressure value when choosing solenoid valves for landscaping irrigation or other applications.
Other than these, there are more factors like medium type, pipe diameter, circuit function, etc. that need to be considered.


Choosing Between Normally Closed & Open Valve

Depending on solenoid valve operation, there are two types of valves. They are -

Normally Open - when de-energized, the valve remains in the “open” position. Typically the normally open type of valve is used in applications where the pressure gets exhausted upon power loss.
Normally Closed - when de-energized, the valve stays in the “closed” position and is the most common operation method. It is typically seen to be used in venting or on/off applications. In case of power loss, the valve shuts and the fluid will not suffer from the exhaust.
