Answering Your Direct Mount Solenoid Question
First and foremost, yes, you can mount a solenoid valve directly onto the unit. This represents one of the most common accessory configurations we supply. For this reason, we design all our units with NAMUR standard mounting interfaces. In short, direct mounting simplifies installation and reduces external piping. Furthermore, this approach creates a cleaner, more compact overall assembly.
Benefits of Direct Solenoid Mounting
To begin with, direct mounting offers several practical advantages over remote installation. Specifically, it eliminates the need for long air lines between valve and cylinder. Additionally, it reduces air volume requirements and improves response times. Moreover, the compact design saves valuable space in crowded installations. As a result, many system integrators prefer this configuration for new projects.

NAMUR Standard Interface Compatibility
Our units use NAMUR standard mounting pads for solenoid valve attachment. This industry standard ensures compatibility with most major solenoid brands. Additionally, standardized hole patterns guarantee proper alignment and sealing. Furthermore, you can choose from 3/2, 5/2, or 5/3 way solenoid configurations. Most importantly, the standard interface simplifies replacement and maintenance tasks.
Solenoid Valve Options Available
We offer a wide range of solenoid options to suit different application needs. For example, you can select 24V DC, 110V AC, or 230V AC coil voltages. Similarly, you can choose between brass or stainless steel valve bodies. Additionally, we provide explosion-proof solenoids for hazardous area installations. Moreover, we stock popular configurations for fast delivery and quick turnaround.
Actuator Solenoid Installation Considerations
Installing a solenoid directly requires attention to a few key details. First, ensure the mounting pad surface is clean and free of debris. Next, use the correct gasket or seal between valve and pad. Then, torque mounting bolts evenly to prevent leaks or misalignment. Additionally, verify proper air flow direction before applying pressure. Most importantly, always follow the manufacturer’s installation instructions carefully.

Air Supply and Pressure Requirements
When adding a solenoid, you must also consider air supply requirements. Specifically, the solenoid must handle the same pressure range as the drive unit. Additionally, you should include appropriate filtration and regulation upstream. Furthermore, ensure the air supply delivers sufficient volume for proper operation. Therefore, we recommend sizing the air lines and components appropriately.
Pre-Assembled vs. Field Installation
You have two options for adding solenoid valves to your units. On one hand, we can pre-assemble and test the solenoid at our factory. On the other hand, you can install the solenoid yourself in the field. Pre-assembled units arrive ready for installation and initial air connection. Field installation offers flexibility for retrofits and existing installations. Either way, the process follows straightforward, well-documented procedures.
Making the Right Solenoid Choice
In conclusion, direct solenoid mounting provides a clean, efficient control solution. To summarize, our NAMUR interface supports easy, direct solenoid attachment. Furthermore, a wide range of options covers most application requirements. Whether you order pre-assembled or install yourself, the process works smoothly. Ultimately, direct solenoid mounting delivers reliable, compact valve control for your system.
