Description   Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Connection types consist of bolt flanges, clamp flanges, union connections, tube fittings, butt welds, socket welds, and internal or external threads.   Gas Valve Types There are many types of gas valves, including: Angle valves admit...

Do you have any advice for people relative to buying or using gas valves?
4 answers
Answers:
Reliability is a must: Check the valve performance not only at ambient temperature but across all the range of operation conditions.
~Erik R, Purchaser, Juarez, Mexico
Use Globalspec and Directindustry web pages to get information about all the technical specifications.
~Luis Fernando C, Engineer, Bogotá, Colombia
Trust not the brand name nor country of origin. Trust the venders that offer the quality products.
~Patrick O, Purchaser, Hong Kong., China
To use same valve as they have.
~Marius Radulescu, Technical Support, Ploiesti, Romania

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of gas valves?
6 answers
Answers:
The library available on emersonprocess.com is a good source to get some knowledge. Of course it is not enough when you are faced with critical applications like pressure control/relief of multiple fluids and gases in chemical reactors but you can gain with those literature if you are looking for the simple and basic applications.
~Hugo B, Engineering Consultant, São Paulo, Brazil
Be thorough with the tests. Know your manufacturer and check if their products have been certified by UL / CSA or AGA. Develop your own intellectual property if you can. Work closely with people with experience in gas valves design.
~Erik R, Purchaser, Juarez, Mexico
Understand what you need the valve for. Do not compromise on quality. Over specify by about 20% unless cost becomes a major factor.
~Wilfred F, Director - Services, Mumbai, India
Use private software and download it from control valves' webpages. It's software probably gives you all the information that you need.
~Luis Fernando C, Engineer, Bogotá, Colombia
Make sure the metal components are properly iced before assembled.
~Patrick O, Purchaser, Hong Kong., China
Use mechanical filter 5 um or 7 um all the time.
~Marius Radulescu, Technical Support, Ploiesti, Romania
