Perrin - 2-Way Trunnion Mounted Ball Valves

SHARE

The mounted 2-way ball valves are designed with a 2- or 3-part housing. Spring-loaded seat rings are used for sealing. Due to the absorption of the forces via the bearing journal and the control shaft, the bearing-mounted ball valve not only has lower torques compared to the floating versions, but can also be used with large nominal diameters and pressure ratings. As standard, these are sealing on the inlet side and can also be supplied as “Double Block and Bleed (DBB)” or “Double Isolation and Bleed (DIB)” versions on request.
