Selecting The Right CNG Valves

Gases are classified as inert, oxidizer or flammable gases. The property of an oxidizer gas is that it is not flammable but contributes to the combustion reaction. Inert gases do not react with other material nor do they aid in combustion. Flammable gases burn or explode when reaction with oxygen.

CNG or compressed natural gas, methane or ethane is a hydrocarbon based flammable gas. CNG like most commodities can be easily stored for a long period of time. It is normally stored in underground storage facilities and transported in the tank.  CNG is required to be transported to diverse locations for various uses. 

Compressed gas valves are used in pipelines to allow or stop the flow of the gas. The compressed gas valve is used to restrict the flow if pipe repair and maintenance is to be carried out. 

How to select the right valve CNG valve

Compressed Natural Gas (CNG) Valves

CNG valves are specifically designed for use with this flammable gas. When you are searching for a valve look for the following key features:

• Choose a compressed gas valve that is manufactured by an automated assembly process
• It is 100% tested for helium leak
• Forged brass, heavy duty body is necessary for durability and safe working under high pressure
• The metal to metal seat below the bonnet provides excellent flow characteristics

Types of CNG valves

As per the design specifications, there are different types of compressed natural gas valves that are widely used in CNG applications. The two types of valves are:

• For working pressure up to 3000 PSI
• For working pressure above 3001PSI to 6000 PSI

The body and bonnet of high quality compressed gas valve are usually made from brass, some models may be chrome plated.  The handwheel is either made from aluminum or steel, while the lower plug can be made from brass or nylon. The stem should be made of brass and the backup O ring of PTFE. These features are the basic in good quality cng valves that offer safety and reliability.

Applications of CNG valves

Chrome plated CNG valves are used in service of methyl fluoride, ethylene, natural gas. The valves are designed to function at different temperatures and pressures for all the gas services. Depending on the utility and functionality of the valve, one can select the inlet and outlet size.

Refill Industrial Cylinders To Reduce Costs And Improve Safety

Cylinders are used in almost all industries ranging from automotive, healthcare, fragrances, electronics, personal care, apparels and environment protection industry. Changing cylinders is time consuming in addition to almost 10% wastage in the form of product loss. Refilling industrial cylinders and industrial tank was the best solution to reduce the product as well as money loss.

Industrial Gas Cylinder

Industrial gases prove to be hazardous if not handled properly. If proper precautions are not followed, the properties of industrial gases may cause injury or even death. Accidents are caused due to negligence, improper handling of the industrial cylinder, improper installation, poor maintenance or handling by untrained personnel.

Precautions when handling gas

• Identify the cylinder contents by the label or tag and never by the color of the cylinder. There is no uniform color coding for the gas industry except for medical gas
• If the label is not legible, return the container to the supplier
• Do not lift the cylinder by the valve or protection cap
• Always secure cylinders in transit
• Use of proper pressure reducing regulator/devices

 Industrial gas hazards

Gases like acetylene, argon, CO2, helium, propane, nitrogen and oxygen have certain hazardous properties which are listed below:

• Flammable : acetylene, propane and hydrogen are flammable gases which explode when mix with oxygen or air upon ignition.
• Asphyxiating : argon, helium, nitrogen and Carbon dioxide cause asphyxia if there is a leakage of the same
• High pressure : industrial cylinders filled with gas are maintained at pressures between 2000 psi to 3000 psi. Proper cylinders and equipment must be used to store or transport the contents
• Extremely cold : gases like helium, hydrogen or oxygen are stored as cryogenic liquids. The vapor and liquid temperatures may range from -109 F to -452 F. The hazard due to its improper handling may cause frostbites or asphyxia
• Oxidizing : oxygen and nitrous oxide are oxidizers. They support the material to burn with an explosive violence

Industrial cylinders are made from aluminum which finds a wide application in medical, food and beverages, specialty gases and more. Manufactured from high strength aluminum ally 6061-TS, this cylinder is light in weight, strong and highly durable.  The cylinders should be ISO designed for reliability and safety.

Refillable industrial cylinders are available for most of the applications. Using the right kind of industrial cylinders, valves or cylinder regulator facilitates refilling of the cylinder. Never attempt to transfer gas from one cylinder to the other or mix the gases.

As we all know, a valve is a device that helps the user to control the flow of the gas or liquid. The valves may control the flow either automatically or manually by opening, closing or partially shutting the passageway. These mechanical devices have become an important tool in piping systems.

 

Valves are an integral part of our daily life. Valves have a wide range of domestic as well as industrial applications. There are different types of valve, some with a pressure relief device, some to be used with liquid, gases or slurries. Valves basically regulate the flow. 

Types of valves

The most common types of gas cylinder valves are ammonia, chlorine, CNG valve, ASB valves,  packed valves, valves with a diaphragm, gate valve, globe valve, line valve, fuse valve and LPG valve to list a few. All the valves have a specific design and application.

The material used to make ASB Valves

ASB Packed Valves

Various metals are used to manufacture valves:

Aluminum: resistant to corrosion, non ferrous metal with a chemical weight 1/3^rd of that of steel

Copper: excellent thermal and electrical conductivity property, corrosion resistant and highly ductile which makes it an ideal material to use for valves that function at higher temperatures

Bronze: it is the first alloy developed and widely accepted for pressure valves and fitting as it has a higher strength than copper. Easy to join and highly resistant to pit corrosion

Silicon Bronze: highly ductile, corrosion resistant and much higher resistance to stress cracking makes it an ideal material for stem in the valve manufacture

Aluminum Bronze: is widely used to make disc in butterfly valves. It is heat treatable, corrosion resistant and very strong, though cannot be used for applications with high pH

Brass: good machinability and corrosion resistant, which makes it the commonly used material for valve and stem in ball valves

Alloys of iron: these are gray iron, ductile iron, cast steel, nickel plated ductile iron, which is used to make valves that are used in pressure vessels. For bonnets, stem and bodies in gate, check or butterfly valves

ASB packed valve is made aluminum, silicon bronze valve that is used in the following applications.

•        Liquid or gas chlorine
•        Insecticides and fumigants
•    Bleaching agents

The body of the ASB packed valve is resistant to corrosive gases. You may choose a ASB Valve with a pressure relief device or without one. This depends up on your applications.
