Bronze Ball Valve

Flanged bronze ball valve has the same action of rotating 90 degrees, the
difference is that the cock body is a sphere, with a circular through hole or
channel passing through its axis. The bronze copper ball valve is mainly used
to cut off, distribute and change the flow direction of the medium in the
pipeline. It only needs to rotate 90 degrees and a small torque to close
tightly. Bronze ball valve are most suitable for use as on-off and shut-off
valves, but recent developments have designed ball valves to throttle and
control flow, such as V-shaped ball valves.
　　
As one of the leading bronze ball valve manufacturers, Carbo produces great
quality China bronze ball valve. Compared with brass ball valve, the main
characteristics of the 3 way bronze ball valve are its compact structure,
reliable sealing, simple structure, and convenient maintenance. The sealing
surface and the spherical surface are often in a closed state, which is not
easy to be eroded by the medium. It is easy to operate and maintain. It is
suitable for water, solvents, acids, and natural gas. The working medium is
also suitable for the medium with harsh working conditions, such as oxygen,
hydrogen peroxide, methane, and ethylene, etc., which are widely used in
various industries. The aluminium bronze ball valve body can be integral or
combined.

How To Repair A Leaking Bronze Ball Valve?
BY CARBO

Here are some instructions from a professional bronze ball valve supplier.
First, it is necessary to find out that the upstream and downstream pipelines
of the ball valve have indeed relieved the pressure before the disassembly and
decomposition operations can be carried out. When disassembling and
reassembling, you must be careful to prevent damage to the sealing surface of
the ball valve copper parts, especially non-metal parts. Special tools should
be used when removing the O-ring. The bolts on the flange must be tightened
symmetrically, gradually and evenly during assembly.

The cleaning agent should be compatible with the rubber parts, plastic parts,
metal parts and working medium (such as gas) in the ball valve, etc are
compatible. When the working medium is gas, gasoline (GB484-89) can be used to
clean metal parts. Clean non-metal parts with pure water or alcohol. The
disassembled individual parts can be cleaned by dipping. Metal parts with
undecomposed non-metal parts can be scrubbed with a clean, fine silk cloth
impregnated with cleaning agent (to prevent fibers from falling off and
adhering to the parts). When cleaning, all grease, dirt, glue, dust, etc.
adhering to the wall must be removed.

Non-metal parts should be taken out of the cleaning agent immediately after
cleaning, and should not be soaked for a long time. After cleaning, it needs to
be assembled after the cleaning agent of the washed wall surface is volatilized
(can be wiped with a silk cloth not soaked in the cleaning agent), but it must
not be left for a long time, otherwise it will rust and be contaminated by
dust. New parts of the flanged bronze ball valve also need to be cleaned before
assembly.

Use grease for lubrication. Grease should be compatible with ball valve metal
materials, rubber parts, plastic parts and working medium. When the working
medium is gas, special 221 grease can be used. Apply a thin layer of grease on
the surface of the seal installation groove, apply a thin layer of grease on
the rubber seal, and apply a thin layer of grease on the sealing surface and
friction surface of the valve stem. When assembling, it should not be allowed
to pollute, adhere to or stay on the surface of the parts or enter the cavity
with metal chips, fibers, grease (except those specified for use), dust, other
impurities, and foreign objects.

What Does A Bronze Ball Valve Do?

First, the fluid resistance of the valve is small, and the full-bore ball
valve basically has no flow resistance. 

Second, this small brass valve has simple structure and light weight.

As a professional brass valve factory, we provide brass water heater drain ball
valve, backwater valve, 15mm copper valve, half inch pex ball valve, etc. Want
