Humphrey Diaphragm-Poppet Remote Air Piloted Valves

Humphrey Remote Air Piloted Valves: Puur Pneumatische Kracht

Humphrey Remote Air Valves offer a reliable solution for switching large volumes of compressed air with a small pneumatic control signal. Because these valves contain no electrical components, they are ideally suited for potentially explosive environments. Inacom supplies these indestructible "Air Pilot" versions in various designs.

The advantage of diaphragm-poppet control

The design of this series is based on the proven diaphragm-poppet technology. Instead of a solenoid coil, the poppet is moved by a pneumatic actuator. For a detailed overview of the technology, consult the official Humphrey Products documentation.

• No lubrication needed: The design works completely dry, which lowers maintenance costs and extends service life.
• Insensitive to contamination: The poppet construction knocks dirt in the air flow away from the seat. As a result, the valve keeps working reliably, even with less clean compressed air.
• Safety first: Because sparking is not possible, these valves are a safe choice for ATEX environments or humid conditions.

Available series and capacity

Humphrey Remote Air Piloted Valves are available in different sizes, indicated by the letter "A" (Air):

1. 250A series (1/4" ports): Compact and versatile pilot valves for general industrial control.
2. 500A series (1/2" ports): Robust brass valves for applications that require substantial flow.
3. 590A series (3/4" ports): The most powerful version for maximum flow in high-flow systems.

Applications of air piloted valves

In systems where the distance between the control and the actuator is large, these valves are essential. They are often used as a main valve controlled by smaller manually operated valves. At Inacom we often see these components in the process industry and heavy machine building. This lets you build a fully pneumatic automation system that lasts for decades.
