Overview
The V-shaped ball valve is an advanced control valve with a
right-angle rotation. Its opening and closing parts are
hemispheres with special V-shaped openings and have sharp
cutting edges. During the rotation of the ball, the sealing
surface has a strong cutting force and self-cleaning
function.
Working principle
The V-shaped opening of the sphere and the valve seat flow
channel form a fan-shaped area. The cross-sectional area of
the flow channel can be changed during the rotation process
to form a linear and proportional adjustment of the medium.
Therefore, the V-type regulating ball valve has both
functions of regulation and switch. It can be matched with
pneumatic or electric actuators. It is commonly used in
control systems in the fields of papermaking, chemical
industry, petroleum, chemical fiber, electric power,
metallurgy, pharmaceuticals, and environmental
protection.
Features
1. The valve body is an integral design, which provides the
valve body with higher strength, can withstand the pipeline
pressure better, and avoids leakage from the shell;
2. The specially designed V-shaped ball has a strong shearing
effect and sealing performance on the medium, and the flow
characteristics of the medium can be adjusted in
proportion;
3. The surface of the sphere adopts hard chromium plating,
nitriding, supersonic spraying and other sealing surface
hardening processes to increase the hardness, wear resistance
and corrosion resistance of the sealing surface.
4. The precision ground spherical surface reduces the
friction between the sealing surfaces, thereby reducing the
torque.
5. The special cover design without valve seat avoids the
dead angle between the valve seat and the valve body that is
easy to block, and avoids the situation of valve seat
jamming.
6. Fixed ball valve structure, upper and lower double stems
and double bearings fix the valve core, which has higher
stability. The bearing is made of composite material and
self-lubricating bearing with sintered bearing surface of the
rotating bearing, which has very strong wear resistance.
