CO2 Regulators - All about Carbon Dioxide Pressure Regulators
Overview Carbon Dioxide regulators are gas cylinder regulators that control the amount of Co2 dispensed for various applications. Some CO2 regulators have flow restrictors that ensure delivery of the gas at a constant rate. These are often used inside draft beer kegerators to dispense just the right amount of the gas to get the perfect foam beer. Continue reading

A Brief about Pressure Relief Valves
Introduction
A Pressure Relief Valve is a type of safety valve that is used to control the pressure in a system that might otherwise disturb the process and consequently lead to system failures. It is designed to open at a pre-determined pressure level to protect other equipment from being damaged due to excess pressure. It aims at protecting property, life and environment.
Functioning of Pressure Relief Valves
Normally, the pressure relief valve remains closed until pressure raises to the desired set pressure. When this level crosses, the valve opens and continues to further open and diverts the excess gas/ liquid to pass away. The valve closes again when the upstream pressure falls below the set pressure.

Thread Sealants - A Complete Guide to Thread Sealants
A Complete Guide to Thread Sealants
What are Thread Sealants?
Thread sealants are sealants that are responsible for achieving a leak-proof seal especially in joints that are dynamically vibrating and changing pressures. Thread sealants majorly come in three varieties: pipe dope, resin compounds and PTFE tape. They efficiently prevent gas leaks from along the pipe threads in cylinders and other gas/liquid equipment when applied properly.

Types of Cryogenic Valves - Applications and Advantages
Cryogenic valves, as the name indicates, are valves that are used in extremely cold applications. Hence these are mostly found to be useful in companies that work with Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG). The valves are commonly found in the oil and gas industries which usually deals with cryogenic temperature ranges starting from as low as -150°C (-238°F). Cryogenic valves are constructed to store such gases safely and also work great during transportation due to their ability to function efficiently in pressure settings as high as 750 psi and temperature as low as -196°C (-320°F).

Valve Uses - The Dos and Do Nots of Valve Use
Do:
Proper care of compressed gas cylinder valves includes (but is not limited to) the following:
- • Store valves packaged so cleanliness is maintained and adequate protection against damage is provided.
- • Visually inspect all valves for leakage and damage at every refill.
- • Reach out to your supplier if the valve is malfunctioning and the problem cannot be diagnosed.
- • Inspect PRD before installing and refilling.
- • Verify the valve is suitable for both the cylinder and its intended use.
- • Open valve slowly to prevent development of high pressure surges and heat generation on down-stream equipment.
- • Only use original manufacturers parts and assemblies when replacing PRD (unless the interchange of parts is proven by manufacturer testing).

CO2 Cylinders - The Dangers of Heat Exposure to CO2 Cylinders
CO2 cylinders are considered full once the weight of the CO2 charge is equal to 68% of the weight of the total water capacity of the CO2 cylinder. This is due to the expansion characteristics of the CO2 charge and the dramatic effects temperatures has on CO2. As temperatures decrease, the CO2 charge shrinks; while when temperatures rise, the CO2 charge will greatly expand. Since the CO2 charge is limited to the capacity of the cylinder, these changes are measured as an increase or decrease in pressure. Continue reading
