Product Details

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.

Technical Parameters

Nominal diameter (DN) :15,20,25,32,40,50,65,80,100,125,150,200,300,450,500.

Nominal pressure (PN): 1.0,1.6,2.5,4.0,6.4(Mpa)ASME150,300LB

Connection form: flange type.

Temperature range: -40~160 (normal temperature); -40~230 (medium temperature); -40~425 (high temperature)

Pressure test: Each valve is tested for shell strength and sealing performance. The shell test pressure is 1.5 times the nominal pressure. The seal test is 1.1 times the nominal pressure. The test medium is water.

Flow characteristics: The flow characteristics of the O-type fixed shut-off ball valve are fast opening characteristics.

Leakage: Metal-sealed seat media tested in the direction of the arrow to meet Class F of the ISO5208 seal rating, equivalent to the ANSI/FCI0.2IV x 1/100 standard. See the table below for details.
