Abstract
A pneumatic valve uses a body made of a synthetic material with a plurality of internal fluid ducts opening onto a face of the body via respective orifices. A metal plate is arranged in contact with the aforesaid face and is provided with sockets aligned with respective ones of the duct orifices and each containing a tapped hole capable of receiving a threaded connecting pipe. Resilient O-rings are used to provide a fluid-tight seal between the sockets and the ducts.
