Project Description



Bronze free flow globe valves or “T” flow.
Recommended for medium pressure water, gas and air systems.
They allow the regulation of pressure or flow rate, modifying the flow of fluid in the pressure pipe. They can also be used as shut-off valves, ie on / off operation.
Non-hazardous gases and vapors up to 1 “1/4 – DN 32 diameter

Maximum working temperature: 80°C
Threading: EN – ISO 228/1

inside the body, the flow area of the fluid is regulated by a moving shutter. When the obturator rests on the seat the valve is completely closed, when instead it is at its maximum distance, the valve is completely open, the intermediate position allows the flow regulation.
They are operated by means of a handwheel placed on the rod.
Inside the valve there is a reduction section, since the flow rate remains constant in the valve, the fluid speed increases.
The closure must be carried out exclusively by hand, without the use of levers, which would compromise the shape of the sealing devices.
Do not exert any force on the cover or on the shell.
In case of high temperatures, use hand protection gloves to act on the switching device.

For a correct assembly, install the valve following the flow direction indicated by the arrow stamped on the body. The globe valve can be mounted both horizontally and vertically. It is not permissible to mount the globe valve with the stem pointing downwards. Globe valves are regulating devices. The use of filters (see our items 411-412-411CM-412CM) is recommended to extend the service life as they are modulating instruments.
Do not exceed with the materia used on the threads for the sealing, the material has to be compatible with the fluid used.
Screw the valve onto the threaded pipes, positioning the key exclusively on the special hexagonal parts up to reach the valve lock on the pipe (this item has a thread-bottom stop where the pipe rests).
After connecting the valve to the pipes, check that the valve is not subjected to stress due to the pipes, then use heavy clamps to support the pipes.
Slowly open the upstream shut-off devices to avoid water hammer.

No maintenance operations are foreseen, except for the adjustment of the screw cap in case of loss from the rod.

For valve operating with hazardous liquids(toxic, corrosive…) , if there is a possibility of residue remaining in the valve, take due safety precaution and carry out required cleaning operation. Personnel in charge must be trained and equipped with appropriate protection devices.
Prior to disposal, disassemble the valve and separate the component according to various materials. Please refer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials) or dispose it, according to local and currently valid legislation taking into consideration the environment.

Performance data, including pressure – temperature ratings have been developed from published standards, supplier material specifications, design calculations and in-house testing. They cover typical applications and are provided as a general guideline.
