Overview:
JBSM is a 3-PC Floating Type Threaded /Welded Metal Seat Ball Valve
of JDV. Features of the product comprise:
1. Anti-static device: Static is generated by valve ball due to friction
with fluid flow, and the static cannot be conducted to exterior of
the body. With the design of anti-static device, static may be
conducted to the exterior of the valve rapidly without explosion or
fire event due to spark generated by static.
2. Valve stem anti-fly device: Old stem is installed in valve from outside.
As there is pressure in the valve, and screw is loosened exceptionally,
the stem would fly out due to the pressure from the valve and result
in industrial accident. The new stem anti-fly design has the stem
penetrates from the interior of the valve without flying out due to
blocking of the valve.
3. Bi-directional sealing seat: The upstream and downstream end have
leakproof seal design, can play a fluid backflow prevention effect,
use INCONEL X-750 shrapnel can reach from the seat tightly sealed.
4. Padlock design: The orientation of the ball valve may be locked to
on or off position as a safety design to avoid hazard because of
careless opening or closing.
5. Balanced pressure relief hole: The ball top is designed with pressure
relief hole to balance the pressure in the inner chamber of the valve,
and prolong the life of ball pad.

Description
This indicates a dangerous situation. Slight or moderate
injury might be resulted if it is not averted.
Death or severe injury might be resulted if such potential
dangerous situation is not averted.
Safety Notification:
Design engineers or product users identify basic product specifications
and check the compliance of valve and installation equipment in order
to guarantee safe use.
Prior to installation of valve, the compliance of operating conditions
(temperature, pressure, fluid characteristics, ambient conditions,
installation gauges etc.) with the service conditions set for valve has
to be checked and identified.
Warning:
Do not get beyond the limitation indicated by valve specification or
technical parameters, or otherwise, death or severe injury might be
resulted.
Warning:
Valve may be used indoors or outdoors. If it is exposed to atmospheric
environment, erosion of valve has to be cared, or otherwise, slight or
moderate injury might be resulted.
Product Transportation/Storage/Maintenance

6 of 18
Warning:
1. In moving or transportation, suitable tools have to be
selected for correct equipments and accessories (sling,
fastener, hook and so forth) in terms of size with
consideration of individual weights of details in the package
and the complete total weight.
2. Ball valve lifting and handling should be operated by
qualified operators. Inappropriate lifting would result in
deformation or dropping of valve to damage the valve.
3. Do not lift the valve using the suspending point or bracket
arranged on cylinder to prevent from danger.
4. Do not use the handle of the manual valve to take or lift
ball valve. In such a way, the handle of the manual valve would
fractured or depart from the valve, such that damage or human
injury might be resulted.
※The product has to be packed well to avoid unnecessary damage when
transportation to and storage in warehouse. Particularly, the
following precautionary measures have to be cared:
Transportation
1. The openings on two sides of the ball valve have to be protected well
using appropriate sealing cover in order to guarantee clean interior of
the valve and prevent foreign objects from entry.
2. The packaging has to guarantee safe transportation to storage site.
As arrival to the storage site, please identify that the covering material
or packing paper or wooden case keeps in a complete status.
Storage & Maintenance

7 of 18
Preserving of Packed Ball Valve
1. Protect the pack adequately to prevent the pack from damage.
2. There should be warning banners for packs to guarantee that the moving
of product would not result in unnecessary damage, such as suspending
center of gravity
3. Flange surface and channel opening have to be protected on the surfaces
of two sides of the ball valve using adequate sealing patch or cover to
guarantee clean interior in the valve and prevent foreign objects from
entry.
4. If the used material of the valve is prone to rust, the flange surface
and the channel opening have to be coated with antirust oil in order for
preventing rust spots from appearing.
5. The storage site has to keep clean and dry.
6. Do not let the product to be exposed to wind/rain or to be sunned.
7. Please check preserving status regularly if the product is to be stored
for a period of time.

8 of 18
Preserving of non-packed/unpacked ball valve
1. Please guarantee appropriate protection of the product in order to
prevent it from damage.
2. In treating large valve, the product has to be fixed safely and stably.
Suitable tools (bracket, hook, fastener, cable) should be used in
transportation. In moving, balance has to be kept in order to prevent
product from damage due to dropping or shaking in transportation process.
Notes for Preparation of Installation
Please follow the following instruction guidelines to guarantee and
prolong product life.
1. Please disassemble the pack (wooden case or pallet) carefully in order
to prevent the product and cylinder and other components from damage.
2. Before installation, remove the seal from flange opening for the air
pipeline containing air filter to clean the interior of the ball valve.
Make sure the clearance of foreign object inside.
3. Make sure that the mark on the nameplate is compliant with service
condition.
4. Make sure that the flow direction on the body meets the direction of
equipment pressure.
5. Make sure that all screws and nuts are secured.

6. In valve installation, please use wrench and follow diagonal sequence
(Figure 1) to lock screws in order to prevent flange from deformation.
Notes prior to Operation
Manual Valve:
1.In manual operation, over or inadequate operation would damage handle
or components, or result in indirect leakage.
2. Please identify that the opened or closed position
※Opened position of ball valve –please identify that the notch
direction on top of stem on the ball valve is parallel to the direction
of the handle and channel, and the ball valve is in opened status.(Figure
2)

※Closed position of ball valve –please identify that the notch direction on top of
stem on the ball valve is vertical to the direction of the handle and channel, and the
ball valve is in closed status. (Figure 3)
Pneumatic Ball Valve:
1. Please operate according to the instructions in the user manual of
the cylinder manufacturer for the action valve to be opened or closed
pneumatically.
