1. Product Introduction:

Perfect for residential or commercial use on water, air, steam, oil or gas, the Lead Free Series Ball Valve is designed to fit for a variety of applications. It is constructed of heavy-duty, corrosion-resistant forged brass and features a lever handle and copper sweat connections on either end. The full port design provides maximum flow and minimum pressure drops

3. Features:

● Drain port allows draining or venting of downstream line when valve is in the off position.

● Blow-out prof, pressure retaining stem.

● Fast, quarter-turn open or close operation.

● Low operating torque.

4. Installation for Solder End (Sweat) Valves:

  Refer to ASTM B828 “Standard Practice for Making Capillary Joints by Soldering of Copper Tube and Fittings”.

Step I: Preheat for soldering by concentrating the heat on the pipe or tube first, then the valve solder cup, always directing the heat away from body joint. The extent of this preheating depends on the size of pipe.

Step II: After preheating direct the heat on valve cap area avoiding the body joint) to aid capillary action in drawing the molten filler metal into the cup.

5.  Advantages of brass ball valves:

● Fluid resistance of this type of valve is very low in fact the full bore valve has practically no resistance at all.

● The brass ball valve has less weight and a simple structure which makes it very easy to operate and repair.

● The seal and ball of the valve are close to each other which makes the valve very reliable and it does not erode easily with the working medium

● It is very useful where regular application and rapid opening and closing is required

● The mounting direction does not limit the flow direction of medium and it is very casual.
