V Port Ball Valve

V port ball valve is a kind of ball valve, its closing member is a hemisphere with a V-shaped opening. v-shaped opening has a sharp edge, in the ball rotation process, there is a wiping effect between the closing member, has a strong cutting off force on the media.

The V-shaped opening of the sphere forms a fan-shaped area with the valve seat flow channel. It can change the cross-sectional area of the flow channel during the rotary process to form a precise regulation of the medium. It is a kind of angle rotary control valve. Its sealing performance is the same as that of ordinary ball valves.

এছাড়াও, it has both regulating and switching functions, and is matched with pneumatic or electric actuators. This design is widely used in industrial process automatic control systems.

V Port Ball Valve Structure

V-type ball valve ball core with V-shaped structure, the spool is 1/4 ball shell. Its features include: V-notch, large flow capacity, adjustable range, shear force, can close tightly, ইত্যাদি. Therefore it is especially suitable for fluid material with fibrous working conditions.

Generally V-notch ball valves are single-sealed ball valves. This structure of the ball valve is not suitable for two-way use.

During the rotation of the valve ball, the V-blade of the ball cuts against the valve seat, thus cutting off the fibers and solids in the fluid. The general ball valve does not have this function, so it is easy to cause the fiber impurities stuck when closing, which brings great inconvenience to repair and maintenance. The V-ball valve has a spool that does not get stuck by fibers.

এছাড়াও, because the v-ball valve adopts the form of flange connection, it is easy to disassemble and install without special tools. It is also simple and easy to repair and maintain.

When the valve is closed, the v-notch creates a covenant scissor action with the valve seat. Such a ball valve design has a self-cleaning function and can prevent the ball core from seizing. It has a metal point-to-point structure for the valve body, cover and seat respectively. এছাড়াও, They uses a stem spring with a low coefficient of friction. Therefore, it has a small operating torque and is very stable.

The V-ball valve is a right-angle rotary structure that enables the flow regulation role. It can achieve different degrees of proportional opening and closing according to the V-shaped angle of the V-ball. V port ball valves are generally used with valve actuators and positioners to achieve proportional adjustment.

Advantages of V-ball Valve

1、Small volume, light weight, easy to operate
2、ভাল sealing কর্মক্ষমতা
3、Easy installation and maintenance
4、Small flow resistance
5、A wide range of applications, from small diameter to a few millimeters to several meters, from high vacuum to high pressure can be applied
6、Strong adjustment performance
7、Small opening and closing torque

As a consequence, these advantages determine the v-type ball valve is widely used in petroleum, chemical and other industrial self-control systems.

The Working Principle of V Type Ball Valve

The opening and closing part of V type ball valve is a sphere with a circular channel. And the two hemispheres are connected together by bolts to rotate 90° to achieve the purpose of opening and closing.

The V-spool valve is most suitable for various regulating situations. Its advantages are: large rated flow coefficient, adjustable ratio, good sealing effect, zero-sensitive adjustment performance, small size, and can be installed vertically. In a word, this type is suitable for controlling gas, বাষ্প, liquid and other media.

Farpro V-ball valve is a right-angle rotary structure, consisting of V-body, pneumatic actuator, positioner and other accessories. It has an inherent flow characteristic of approximate equal percentage ratio. Has a double bearing structure with low starting torque. So this V port ball valve has excellent sensitivity and sensing speed with superb shearing capability.
