What is a Solenoid Pilot Valve

A solenoid pilot valve for valve monitoring and control solutions is an electromechanical device used in industrial and fluid control systems. It typically consists of a solenoid coil and a valve body. The solenoid coil is energized when an electrical current is applied, generating a magnetic field. This magnetic field moves a plunger or armature inside the valve body, which in turn controls the flow of fluid through the valve.

These valves are commonly used to open, close, or modulate the flow of fluids in pipelines or systems via controlling the airflow to a valve actuator. They play a crucial role in automated processes, as they can be remotely controlled by electrical signals. They are often employed for tasks like shutting off gas or liquid flow in emergency situations or directing fluids to specific parts of a system.

The Falcon II and Falcon V solenoid valve is an integral part of Westlock Quantum control monitors and is engineered specifically to address low power valve actuation requirements. It is available for single-acting or dual acting actuators.

Falcon™ II: Unveiling the Features and Advantages

• Demonstrates exceptional performance with air leakage at steady state of less than or equal to 5 cc, minimizing losses.
• Offers an optional extended low-temperature seal rated at -58°F (-50°C).
• Provides both single and dual coil options, with a fail-center option available for fail-freeze applications.
• Stand-alone versions are available for all materials to meet diverse requirements.
• Proven to excel in high-cycle applications, ensuring reliability and longevity.

Westlock’s Falcon™ II and Falcon™ V solenoid valves provide multiple overriding options for applications where the process demands local safety checks before starting or stopping. Solenoid valves are used to stop a process from starting automatically or vice versa.

Troubleshooting is made simple with Westlock’s Quantum series, allowing solenoid coils to be easily removed without dismantling tubing, saving significant time and money. Westlock’s Falcon™ II and Falcon™ V solenoid valves are equipped with a spool position indicator. When energized, the airflow shifts the spool & the indicator turns red. If the spool position does not match the beacon, there is an issue with the actuator and valve assembly. You can eliminate the control box as the source.

Ease of maintenance with the removal of just two screws; the valve body can be efficiently detached without the need to access the enclosure, streamlining maintenance procedures.

In valve monitoring and control solutions, these solenoid pilot valves are essential components that enable operators to manage and regulate fluid flow, ensuring the proper functioning of various industrial processes and systems. They are known for their reliability, quick response times, and ease of integration into automated control systems.
