Q61Y welded high-pressure hard seal ball valve
High pressure resistance: pressure can reach 1.6Mpa-42Mpa; Class:150-2500Lb
High temperature resistance: The valve seat of this ball valve adopts the structure of an American standard gate valve, so the temperature is determined by the valve body material.
Friction free: This ball valve utilizes the advantages of a two-piece spherical body when opened, first horizontally collapsing and instantly disengaging from the valve seat, and then rotating 90 degrees to fully open.
The characteristics of Q61Y welded high-pressure hard seal ball valve metal hard seal floating ball valve:
1. The valve seat adopts a cylindrical spring and truncated metal hard sealing structure, which can adapt to higher temperatures and various dust and solid particle media.
2. Adopting a bottom mounted valve stem and a reverse sealing structure to ensure reliable sealing at the packing and prevent the valve stem from coming out.
3. It has fire and static electricity prevention functions.
4. The handle and valve stem are connected in a flat square shape. Locking structures can also be added as needed to prevent misoperation.
5. This structural ball valve should be used according to the specified flow direction.
