Kobelt 3328 - Normally Open Adjustable Differential Air Pilot Relay Valve, 1/4" NPT, Maximum Pressure 200 PSI, Poppet-Type, Air Flow Control

The Kobelt 3328 Normally Open Adjustable Differential Air Pilot Relay Valve is designed for precise control of air flow in various applications. This valve uses a poppet-type mechanism, with a diaphragm spring that forces the valve stem down, keeping the poppet open. This design ensures that air flows from the source supply directly to the device being actuated. The 3328 is available in various light to heavy-duty configurations, providing flexibility for different system requirements. Its pipe port size is 1/4" NPT, and it is rated for a maximum supply pressure of 200 PSI (13.8 BAR).

The 3328 valve is a reliable solution for applications that require consistent and controlled air flow. It comes in a normally open configuration and is ideal for systems where air needs to flow immediately once the valve is activated. The valve is suitable for a wide range of industrial and marine applications, offering durability and performance over time. The 3325 valve is the non-differential version of this model. Key features include:

• Poppet-type design for reliable air flow control
• Normally open configuration for immediate air flow once activated
• Available in a range of light to heavy-duty spring configurations
• 1/4" NPT pipe port size for easy installation
• Maximum supply pressure of 200 PSI (13.8 BAR) for robust performance
• Ideal for industrial, marine, and other demanding applications
• Durable construction for long-term use in harsh environments

The Kobelt 3328 valve offers a high level of control and reliability, making it an excellent choice for systems that require precise and adjustable air flow management.
