Project Description



Bronze threaded gate valves, available in the following versions:

200: Heavy type, FxF, PN25

210/10S: Normal type, FxF, PN16

245: Quick opening, FxF, PN10

Gate valves can be horizontally or vertically installed. The slow and proportional manoeuvre avoid the water hammer phenomenon. Pay attention during the installation phase, especially for the small size ones, avoid forcing the pipe screwing in order not to deform the sealing seats. Gate valves can also work at an intermediate position of the opening, so as to reduce the flow into pipes.

OPERATION (for gate valves with handwheel)
OPENING: an anti-clockwise rotation of the hand wheel will open the valve. When it will go no further return the hand wheel clockwise 1/2 turn.
CLOSURE: a clockwise rotation of the hand wheel will close the valve. Closure will be confirmed when the handle can be turned no further.
CAUTION: Service applications with extremes of temperature may cause the wedge to become tight in the valve. The valve may be become stiff to operate in these circumstances. Suitable hand protection should be worn when operating valves used in extreme temperature applications.

Valves must be installed in a piping system whose normal pressure and temperature does not exceed the stated rating of the valve. It may be hazardous to use these valves outside of their specified pressure and temperature limitations. To ensure ease of operation, adjustment, maintenance and repair, valve siting should be decided during the system design phase. To prevent imposing strain on the valve seat, pipe work and valves must be adequately supported.

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.
