Factory Free sample Brass Nrv - JL-0101.Ball Valve – Jielong

Product description

brass ball valve is a flow control device which uses a hollow, perforated and pivoting ball to control liquid flowing through it. It is open when the ball’s hole is in line with the flow inlet and closed when it is pivoted 90-degrees by the valve handle, blocking the flow.The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve’s status. The shut position 1/4 turn could be in either clockwise or counter-clockwise direction.

Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack the fine control of those alternatives, in throttling applications.

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.

Installation for Solder End (Sweat) Valves

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.

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.
