Kobelt 3324 - Normally Closed Adjustable Relay Valve, 1/4" NPT, Die-Cast Silicon Bronze, Maximum Pressure 700 PSI

Kobelt 3324 - Normally Closed Adjustable Relay Valve, 1/4" NPT, Die-Cast Silicon Bronze, Maximum Pressure 700 PSI

The Kobelt 3324 Normally Closed Adjustable Relay Valve is a high-quality, durable poppet-type valve designed for precise control in pneumatic systems. It features a spring-loaded design that keeps the valve in a closed position until pilot pressure is applied, which opens the valve to allow airflow to the device being actuated. With a maximum pilot pressure of 700 PSI and control pressure up to 200 PSI, the Kobelt 3324 is commonly used in marine propulsion applications, specifically for clutch and throttle interlocks. This valve ensures smooth operation by locking the forward or reverse clutch in gear until hydraulic pressure activates the valve and allows the throttle signal to pass through to the engine speed setting device.

Built with a robust die-cast silicon bronze construction and stainless steel hardware, the Kobelt 3324 is designed for reliability in harsh environments. It offers a wide range of pressure settings with the option for different spring configurations to suit various applications. Key features include:

• Normally closed valve controlled by piston and spring arrangement
• Maximum pilot pressure: 700 PSI (48 BAR)
• Maximum control pressure (pneumatic): 200 PSI (13.79 BAR)
• Durable die-cast silicon bronze and stainless steel construction
• Wide operating temperature range: -40°C to +90°C
• Pipe port size: 1/4” NPT
• Various spring options available for different pressure ranges
• Commonly used in clutch and throttle inter-locks in marine propulsion systems

The Kobelt 3324 valve ensures smooth and reliable operation in critical systems, especially where precise pressure control is essential. Its versatility and strong construction make it ideal for marine and other industrial applications.
