One Piece Ball Valve vs. Two Piece Ball Valve
Ball valves are ubiquitous in our daily life, and most places where there are switches will have them. It is more convenient to operate, has better sealing, wear resistance and corrosion resistance, so it is widely used. There are many types of ball valves. Below, ATO will take you to understand the characteristics of industrial one-piece ball valves and two-piece ball valves and what are the differences between them.
One piece ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, not easy to wear the seal, and small opening and closing torque. This reduces the size of the fitted actuator. Equipped with a multi-turn electric actuator, the medium can be adjusted and tightly shut off. It is widely used in petrochemical urban water supply and drainage and other working conditions that require strict cut-off.
The industrial two-piece ball valve and gate valve are the same type of valve. The closing part of the two-piece ball valve is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing. The working principle of the two-piece ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, the sealing surface and the spherical surface are often closed, and are not easily eroded by the medium, and are widely used in various industries.
The difference between one piece ball valve and two piece ball valve:
The working principle is different:
The working principle of the one-piece ball valve is the mechanical pressure of the valve stem; the working principle of the two-piece ball valve is to make the valve unblocked or blocked by rotating the valve.
The valve body of the ball valve is different:
The one-piece stainless steel ball valve is a manual valve. The structural design is integral, and the ball is stabilized by a plug, which is convenient for maintenance. The diameter of the ball valve is also small, and the ball is put in from one side of the valve body after the valve seat is screwed in, then press the ball; the two-piece ball valve is fixed by two pieces of the valve body clamped by the ball, the maintenance is relatively complicated, and the tightness of the bolt in the middle is very important.
The closing parts of the ball valve are different:
The closing part of the one-piece ball valve is a sphere, and the ball rotates around the center line of the valve body to open and close a valve; while the two-piece ball valve has no special requirements.
The ball valves can be used for fluid regulation and control. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal valve seat of hard alloy surfacing, and is especially suitable for fibers containing fibers and tiny solid particles. etc. medium. ATO offers one piece, two pieces, three pieces of stainless steel ball valves, sizes are available in 1", 1/4", 2", 3".
