| Detailed Description: |
The construction adopted by UNIVER for the spool system allows extremely interesting performances. The valve is made of only two parts, body and spool (in one piece) with fluctuating seals of special compound which reduce friction and prevenct sticking. The aforementioned features together with a high flow capacity as well as the absence of comunication between the chambers during commutation make maintenance easier, lubrication not necessary and allow a high cycle life. Apart from the typical uses of the spool system, this valve is also suitable for vacuum application, for 5/3 open centres or 5/3 closed centres |
