365N-V Automatic Liquid Shut-Off Vessel

365N-V Automatic Liquid Shut-Off Vessel – 1/2" NPT

The Headline Filters 365N-V Automatic Liquid Shut-Off Vessel is designed to protect gas analysers, sample conditioning systems and other sensitive downstream instrumentation from unexpected liquid carryover.

The vessel captures slugs of water or condensate entering the process or sample line before they can reach expensive downstream equipment.

As liquid collects inside the transparent nylon bowl, the internal PVC float mechanism rises with the liquid level. When the collected liquid reaches the shut-off level, the float-operated cone automatically closes the outlet flow path, stopping further flow downstream and helping prevent liquid from passing into the analyser or instrumentation.

Once the source of the liquid ingress has been identified, the collected liquid can be removed using the manual brass drain at the base of the bowl.

Key Features

• Helps protect analysers and instrumentation from liquid carryover
• 1/2" NPT process connections
• Aluminium head
• Transparent nylon bowl for visual inspection
• PVC float and shut-off cone mechanism
• Manual brass drain
• Fully mechanical operation
• No electrical supply or external control system required
• Suitable for gas and analyser sample conditioning applications
• Designed to provide protection against unexpected slugs of water or condensate

How It Works

During normal operation, gas flows through the 365N-V while the internal float remains in its lower position.

If water or condensate enters the line, it collects within the nylon bowl.

As the liquid level rises, the PVC float rises with it. When the liquid reaches the predetermined shut-off level, the float-operated cone closes the outlet and stops downstream flow before the collected liquid can pass out of the vessel.

The bowl can then be manually drained before the system is returned to normal operation.

Typical Applications

• Gas analyser protection
• Process analyser sample conditioning
• Continuous Emissions Monitoring Systems (CEMS)
• Emissions analyser systems
• Instrumentation protection
• Gas sampling systems
• Condensate protection
• Moisture removal systems
• Process and laboratory gas systems

Construction

Protecting Sensitive Downstream Equipment

Unexpected condensate or a sudden slug of water can cause contamination, measurement errors or damage to sensitive analyser equipment.

Although filters and separators can remove normal levels of entrained liquid, a larger volume of liquid can overwhelm a conventional sample conditioning system.

The 365N-V Automatic Liquid Shut-Off Vessel provides an additional layer of protection by mechanically shutting off downstream flow when the liquid reaches the shut-off level, helping prevent liquid breakthrough and protecting valuable analyser and instrumentation equipment.
