RB series O type ball valve
It is a right angle rotary type shut-off valve.It is used with
pneumatic actuators or electric actuators to achieve remote
shut-off control or manual control with a wrench or handwheel. The
structure adopts a movable seal to make a two-way seal design. It
has large shearing force and self-cleaning function when there is
no gap between the two-way sealing valve seat, especially suitable
for controlling the suspension with fibers and fine solid particles
or viscous media on and off. Therefore, this product is widely used
in the automatic control systems of chemical, biochemical,
petrochemical, polycrystalline, environmental, pharmaceutical,
light industry, paper and other industrial sectors.
Design Featur
Valve body
The valve body adopts a diameter design and has a small flow
resistance.
Valve stem
The outer circle is made of coreless grinding, and the friction
coefficient between the filler and the packing is small. The
friction loss is minimized, and the valve opening and closing
torque is greatly reduced.
Self-lubricating bearing
The upper and lower stems are fixed with double bearings for
extremely high rotation accuracy and rotational stability. The
bearing is made of a special process of sintering copper on a
stainless steel surface and then rolling PTFE on the copper
surface. It has excellent wear resistance and self-lubricating
function, which avoids the valve stem and bearing seizure
phenomenon in the long-term use of the valve.
Spool
The fixed valve core design has small opening and closing torque,
flexible opening and stable operation.
Seat
The metal sealing ball valve adopts a two-way metal movable sealing
structure, which adds a pre-tightening spring with automatic
compensation and self-cleaning function. Because of the two-way
seal, the valve body is installed without regard to the flow
direction of the medium.

Note: The ZSQ and ZDQ actuators are developed by our company. See
the Z series actuator samples for details. The above valve actuator
is configured to have a nominal valve pressure of 1.6 MPa at normal
temperature, and a pneumatic actuator with a source pressure of 0.5
MPa is recommended. If the valve nominal pressure is greater than
1.6MPa, the actuator configuration will be recommended separately.
