How To Choose The Right LPG Valve As Per Your Requirement?

Liquefied Petroleum Gas (LPG) constitutes hydrocarbons such as propane and butane. It is an odorless and inflammable fuel which requires the right components for safe usage in various applications. LPG valve manufacturers offer different types of valves such as safety relief valve, ball valve, etc. for the handling of LPG. Let’s take a look at some of the factors to choose the perfect LPG valve for your requirements.

1.  Quality of the valve

Safety valves are manufactured in accordance with the leading quality standards by reputed LPG gas valve manufacturers. India’s ball valve manufacturers offer a wide range of valves for LPG applications that have passed the IS quality standards such as IS: 4576.

2.  Application of LPG valve

LPG valves are used as cooking fuels and for a number of industrial as well as commercial applications. Discuss your requirement with a valve manufacturer to understand what kind of valve will be suitable for your application.

3. Performance of the valve

The purpose of a pressure safety valve is to protect the life and property in the LPG environment from hazards due to overpressure. Choose the valve model that will open effectively at the set pressure.

While handling pressure in boilers, the Maximum Allowable Working Pressure (MAWP) of the equipment should be considered before selecting a valve. The safety valve must be set to open at or below the equipment’s MAWP. Discuss the set pressure of your valve with your valve manufacturer while choosing a valve.

4. Features of the valve

Safety valves come in standard sizes with different kinds of inlet and outlet connections. For common applications, you may find your perfect valve among the range of standard size valves available in the market. If you have a specialised project or mechanism, you may need to customise the valve features such as material, design, type, etc.

 The features of the valve impact its performance. So, list down the performance expectations from the valve, then look for the valve with the right features. For example, the temperature can affect the viscosity of the gas or fluid passing through the mechanism. Materials such as steel, iron, and bronze can give varying output for a particular application where the temperature of the contents passing through the valve has to be kept within a specific range. So, choose the material for the valve as per the temperature guidelines for your desired application.

5. Cost and Maintenance

For your requirement, you may have a budget. Your procurement cost will be higher if you go for a customized valve. Also, during the maintenance of the valve, you may get standard valves easily but for customized valves, your replacement costs may be higher.

 You need to choose an expert among LPG valve manufacturers to get the best valves at the best rates. Additionally, note that you are researching to choose a valve for ensuring safety so you should consider expanding your budget to a comfortable extent instead of compromising the safety of your people and property which can turn out to be more expensive if overlooked.

A Comprehensive Guide to Excess Flow Check Valves and its Features

Excess Flow valves also referred to as velocity check or seismic valves, are created to shut down immediately after a sudden surge of flow. An excess flow valve is basically an in-line valve via which liquid or pressurized gas flows in both the directions. They shut down after excessive discharge of vapor or liquid caused due to the breaking of the pipe system. After the flow rate has exceeded the setting of the valve, it continues to remain closed till the time system pressure becomes stable. In case the flow doesn’t exceed, the valve’s setting won’t close.

A leading number of excess flow check valve manufacturers are manufacturing innovative and affordable valves, which are available in different configurations, flow rates and sizes, based on the vessel’s construction and the desired flow rate that are crucial for completing the process. Read on to find out more about excess flow check valves and their unique features.

Excess flow check valves

The excess flow check valves can be easily purchased in numerous pressure materials, classes, end connections and flange designs. These valves undergo stringent check in a certified flow laboratory for performance and durability. The excess flow valve is basically a spring loaded check valve that closes only after flow of vapor or liquid via the valve produces sufficient force or flow for overcoming the strength of the spring that helps in keeping it open. Each of these valves is available in multiple sizes as well as flow rates based on the reason for which they’re being used. It is important to determine the purpose for which the valve will be used prior to installing it. The excess flow valves are utilized for different fluids as well as processes including excess flow check valve for lpg gas, anhydrous ammonia, butane, nitrogen air, anhydrous chlorine, water etc.

They allow vapor or liquid to flow in different directions. The flow is usually controlled in one specific direction as each of the valves come with an arrow. Hence, when the flow in the desired direction surpasses the already determined flow rate, the excess flow check valve closes automatically.

The disk of the valve remains in an open position with the help of a spring. After the vapor or liquid flow results in a drop in the pressure across the disc of the valve that is exceeding the present flow rate, the disk of the valve closes against the valve’s opening to hinder the flow of the liquid or vapor. This valve disk remains closed till the time the pressure between both the downstream and upstream sides of the flow check valve equalizes. After the pressure equalizes, the flow check valve will open automatically. As a result, when the line’s broken or ruptured, the pressure towards downstream won’t equalize and the valve won’t open till the time the line’s been repaired.

To sum up, excess flow check valves are ideal for handling fluid components for oil and gas, chemical as well as petrochemical industries as well as water blast organizations.
