OVERVIEW

Industrial Grade CGA 320 Valve for Carbon Dioxide Service

The GV32051-LX is a premium-quality cylinder valve designed specifically for the control and regulation of Carbon Dioxide (CO2) in high-pressure cylinders. Manufactured to meet strict industrial standards, this valve utilizes the Compressed Gas Association (CGA) 320 connection standard, making it universally compatible with CO2 regulators and transfer equipment used across North America. The valve body is constructed from heavy-duty forged brass, a material chosen for its exceptional strength, durability, and resistance to corrosion, ensuring a long service life even in demanding industrial environments.

At the core of this valve's design is safety and reliability. It features a standard 0.750-14 NGT (National Gas Taper) inlet thread, which is the industry standard for the majority of steel and aluminum high-pressure gas cylinders. This ensures a secure and precise fit into the cylinder neck. The valve is equipped with an integrated Pressure Relief Device (PRD), a critical safety feature that automatically vents gas if the internal cylinder pressure exceeds safe limits due to heat exposure or overfilling, thereby preventing catastrophic cylinder failure.

Operation of the GV32051-LX is smooth and reliable, thanks to precision-machined internal components and a high-quality stem packing system that prevents leaks around the handle. The ergonomic handwheel is designed to provide sufficient torque for positive shut-off while being easy to operate, even when wearing heavy work gloves. It is important to note that the CGA 320 connection requires the use of a flat sealing washer (nylon or fiber) between the valve face and the regulator nipple to ensure a gas-tight seal; this is a distinct characteristic of the CGA 320 standard compared to other inert gas fittings.

Whether used for industrial welding supply, beverage carbonation systems, or specialized laboratory applications, this valve provides the consistent performance professionals demand. Its robust design minimizes maintenance requirements and maximizes uptime, making it an essential component for any fleet of CO2 cylinders.

FAQ

CGA 320 is specifically for Carbon Dioxide (CO2) and uses a flat face with a required sealing washer. CGA 580 is for inert gases like Argon, Helium, and Nitrogen, uses a bullet-nose nipple, and does not require a washer.

No, the valve itself does not typically come with the washer. The washer is usually supplied with the regulator or sold separately as a consumable item.

The inlet thread is 0.750-14 NGT (3/4 inch National Gas Taper), which is the standard thread for most North American high-pressure gas cylinders.

No. You should never put an Argon valve on a CO2 tank or vice versa. The connections are different to prevent cross-contamination and safety hazards.

Valve installation requires specific torque settings (usually around 50-60 ft-lbs for brass valves in aluminum cylinders, but verify with cylinder specs) and should be performed by a certified cylinder technician to ensure safety.

The safety relief device, or burst disc, is designed to rupture and vent the gas if the pressure inside the cylinder rises to a dangerous level, preventing the cylinder itself from exploding.

Yes, as long as the aluminum cylinder has the standard 3/4"-14 NGT neck threads. Always check your cylinder's specification stamp before installation.

For CGA 320 connections, a leak at the nut usually means the sealing washer is missing, damaged, or deformed. Replace the washer and retighten.
