If you don’t know your blow down from your pop action, NASVI has you covered. Here is a handy cheat sheet on safety valve lingo and how to accurately order them.

SAFETY RELIEF VALVE:Safety relief valves are basically like pop safety valves and are primarily for liquid service where the thermal expansion in a liquid-laden vessel actuates the valve. When vapor is generated in these vessels, due to uncontrolled heat input, this valve with the huddling chamber, will give a high disc lift and discharge the expanded vapors. This valve is also suitable for gas or vapor service.

SELECTION OF VALVE:Valves should be selected for the particular installation on which they are to be used and also on the basis of the rated discharge capacity. This should be equal to or greater than the maximum output of the system.

INSTALLATION:The valve is to be installed in a vertical position, into a clean fitting, using the proper size and type of wrench so as not to damage the valve. The discharge piping, without stop valves, shall be independently supported and sloped downward slightly to drain condensate.

Of all the challenges you face keeping your customers’ plants operating at full capacity, safety and relief valves shouldn’t be one of them. NASVI’s job is to give you the confidence that your valve supply chain is rock solid regardless the pressure it’s under.

Safety valves are used in a variety of applications, including air/gas, vapor, steam and liquid service.  Flotech has been approved by the National Board of Boiler and Pressure Vessel Inspectors to perform safety and relief valve testing, repair and certification.

Our valve experts will focus on getting your valves tested, repaired and quickly set to the exact specifications.  We evaluate the repair condition of every valve and will recommend the right solution to manage your maintenance program.

Some people have proposed a “safety valve” to control the costs of a cap-and-trade policy to fight global warming. This post explains what a safety valve is, and why it provides only an illusion of cost management.

In a cap-and-trade program, companies can choose either to lower emissions below the cap, or buy extra allowances. Some worry that if many companies need to buy extra allowances, demand will drive up the price, placing an undue burden on businesses.

The “safety valve” or “escape hatch” is meant to address this. It specifies that when prices reach a predetermined dollar value, businesses no longer have to rely on the established supply of allowances available in the market. Instead, the federal government makes new allowances available for sale at a specified price – potentially in an unlimited quantity.

There are two problems with this approach:A safety valve destroys the cap. The hard limit on emissions is the cornerstone of a cap-and-trade policy. Without a solid cap, we can’t be sure our emissions will go down enough to avoid the worst consequences of global warming. A safety valve gives the illusion that we are controlling emissions while allowing more greenhouse gas pollution into the atmosphere.

A safety valve limits the economic opportunity of those who develop cleaner technology. Higher permit prices signal the market to invest more in innovative low-carbon technologies – happy news if you’re in the business of inventing and selling ways to cut pollution. A safety valve would sharply curtail incentive for innovation. This drives up costs in the long run, and discourages the development of the clean technology we need.

A safety valve seriously undermines the main advantages of a cap. Its ability to control costs is an illusion, it lets more pollution into the atmosphere, and discourages entrepreneurs from investing in pollution-cutting technology.
