Product Description
The trunnion mounted ball valve has small torque, small deformation of the valve seat, stable sealing performance
and long service life, and is suitable for high pressure and large diameter. Advanced spring pre-seat assembly with
self-tightening properties for upstream sealing. Each valve has two valve seats, which can be sealed in each direction,
so the installation has no flow direction restriction and is bidirectional.
