Solenoid valves are valued for their response speed, reliability, and ease of use in automated systems. Solenoid valves are one of many different control valves, though, and are inappropriate for every application.

This article compares solenoid valves to five other types of shutoff valves. It focuses on the advantages and disadvantages of each. Read our solenoid valve overview article for more information about this type of valve.

Advantages and disadvantages table

Table 1 offers a very brief comparison of solenoid valves to other control valve types. The other valves discussed in this article are gate valves, butterfly valves, ball valves, needle valves, and angle seat valves. Each piece of information in Table 1 is in comparison to solenoid valves. For example, the table describes the response time of gate valves as slower. This means that gate valves have a slower response time than solenoid valves.

Valve type Response time Flow control Flow capacity Pressure rating Temperature rating Cost
Gate valve Slower on/off Higher Higher Higher Lower
Needle valve Slower on/off and proportional Lower Higher Higher Similar
Butterfly valve Slower on/off and proportional Higher Similar Higher Similar
Ball valve Slower on/off Higher Higher Higher Lower
Angle seat valve Slower on/off Higher Higher Higher Lower

Table 1: Brief overview of various valve types compared to solenoid valves. Response time "slower" for gate valves means that a gate valve has a slower response time than a solenoid valve.

Solenoid valves vs other control valves

Compared with other control valves, solenoid valves have several advantages and disadvantages. This section takes a closer look at these factors by giving further information on the brief overview in Table 1.

Response time

One of the most significant advantages of solenoid valves over other valve types is their response time, which is nearly instantaneous in the low milliseconds. This response time is necessary for applications such as fuel injection in automotive systems, regulating pressure in a hydraulic system, and controlling airflow in an HVAC system.

Flow control

All of the valves this article discusses are, in their basic form, on/off control valves. Solenoid valves, above all others, are valued for their near instantaneous switching between fully open and fully closed states. Beyond on/off control, though, proportional solenoid valves can modulate flow.

Needle valves and butterfly valves also allow for precise flow control between the on/off states. A standard ball valve does not allow for this, but a v-port ball valve does. Angle seat valves and gate valves do not offer precise flow control.

Flow capacity

Besides needle valves, all valve types in this article have higher flow rates than solenoid valves. While indirect solenoid valves can handle higher flow capacities than semi-direct and direct-acting solenoid valves, they still have much lower flow capacities than control valve types. For example, a 2.5-inch indirect solenoid valve may have a Kv value of 40 cubic meters per hour. In contrast, a 2.5-inch ball valve has a Kv value of 320 cubic meters per hour. To learn more about how to measure flow rate, read our Kv calculator article. For imperial units, read our Cv calculator article.

Power source

Solenoid valves are always electrically controlled and therefore require electricity to operate. The other valves discussed in this article, however, are manually controlled. That being said, each valve can be controlled by electric, pneumatic, or hydraulic actuators to overcome the limitations of manual control.

Media purity

There should not be any contaminants or particles in the media flowing through a solenoid valve. These can easily clog the valve, causing it to stay in the open position, and damage the internal components. Needle valves and angle seat valves similarly work best with clean media. Butterfly, ball, and gate valves, though, can operate better with contaminated media, making them ideal for situations such as wastewater applications. Ultimately, though, valves do work best with media that does not contain contaminants or particles.

Pressure rating

A significant disadvantage of solenoid valves is that they cannot handle as high pressure as other control valves. Among the valves discussed in this article, only butterfly valves have a max operating pressure limitation similar to solenoid valves. Angle seat valves are slightly higher, and needle valves, ball valves, and gate valves have max operating pressures significantly higher. Therefore, the latter three valves are often employed in high-pressure industrial processes.

Temperature rating

Solenoid valves also have a relatively low max operating temperature. This is due to the electrical components in the valve that can easily be damaged at temperatures above 120 °C (250 °F). The other valves discussed in this article do not have electrical components in their standard designs but can be actuated by electric actuators. Using an electric actuator can reduce a valve's suitability for high-temperature applications.

Using the right valve for a particular application is essential, maximizing the application's efficiency and the valve's lifetime. It's not simple to choose just the right valve for every application since some applications can use multiple types. Always study the application's parameters (e.g., max operating pressure, temperature, and environment) to determine whether or not a particular valve meets the needs.

When should I choose a solenoid valve over other valve types for my application?

Choose a solenoid valve for low-pressure applications that require remote actuation, fast response, and rapid opening and closing of the valve.
