Brass valves require a little more preparation than regular copper joints, as the inside stem where the rubber/plastic can be found needs to be protected from the heat of the propane torch. If a ball valve exists and can't be removed, open the valve so the plastic ball has a minimum connection to the heat.
The one home inspection item that consistently causes home buyers to ‘freak out’ more than anything else is a gas leak. Gas explosions like the ones that recently happened in Edina and Saint Paul are probably the main causes of all the paranoia about natural gas. Believe it or not, small gas leaks are actually quite common at old houses, and they’re usually simple for a plumber to fix. Today I’ll share the most common locations for gas leaks, and I’ll share my home inspection techniques for finding gas leaks in old Minneapolis and Saint Paul home...
When replacing old taps with new ones the most difficult part of the job is likely to be (as with so many plumbing operations) removing the old fittings. Let's first consider wash basin taps.
You must, of course, cut off the hot and cold water supplies to the basin. The best way of doing this will usually be to tie up the float arm of the ball valve supplying the cold water storage cistern so as to prevent water flowing in. Then run the bathroom cold taps until water ceases to flow. Only then open up the hot taps. This will conserve most of the expensively heated water in the hot...
Top burner gas valves are fairly easy to replace. With the top plate (bull nose) removed you can access them easily (part of the frame runs across the top of them). If you are replacing all or just one, the burners must be removed if they have a slip type orifice. If there is a tube type burner valve they need not be removed because you can disconnect the tube from the burner valve and move it out of the way.
In either case when the burners or the tube is disconnected take a wrench and screw out the valve being replaced (in some cases you may have to remove a pil...

Is pleased to announce the introduction of their newest product, the Series DX Slurry Knife Gate Valve.
The Series DX Slurry Knife Gate Valve is recognized as the most durable and user-friendly knife gate valve. It is designed especially for heavy slurry applications in the power and mining industries.
When the Series DX valve opens, the reinforced elastomer sleeves seal against each other and provide a 100% full port opening, minimizing turbulence which in turn minimizes wear. The seats isolate and protect all metal parts of the valve from coming in contact with the pro...

Body and bonnet The main parts of a valve are the body and the bonnet. These two parts form the casing that holds the fluid going through the valve. The bonnet is the casing through which the stem (see below) passes and that forms a guide and seal for the stem. Valve bodies are usually metallic[citation needed]. Brass, bronze, gunmetal, cast iron, steel, alloy steels and stainless steels are very common.[citation needed] Plastic bodies are used for relatively low pressures and temperatures. PVC, PP, PVDF and glass-reinforced nylon are common plastics used for valve bodies.[citation n...
Parker Instrumentation has published a guide to its high-performance instrumentation ball valve family for instrument and process applications, Hi-Pro.
Featuring a novel two-piece construction that reduces potential leak paths to a minimum, and a design optimised for reliability, the 10,000 lb/in2/689 bar valves are ideal for long-lifecycle applications.
Available in four basic bore sizes of 10, 15, 20 and 25mm, the application scope for Parker's valve is very wide and spans areas such as isolation on process lines, vessel draining and venting, and hydraulic applications.
The guide det...

Ball valves consist of a ball that is turned on a vertical axis. A flow passage is bored through the centre of the ball to allow fluid flow. When the flow passage is aligned with the inlet and outlet of the valve, the fluid can flow through the valve. When the ball is turned 90 degrees so that the flow passage is perpendicular to the valve ports, fluid will not flow. For pneumatic applications, bronze ball valves are most commonly used, although ball valves are available in steel and stainless steel construction. Ball valves are available as a two-...
