The Fisher 8590 high-performance butterfly valve offers three connection options – splined, square, or keyed shaft – providing flexible compatibility with various actuators to meet different installation requirements.
Its innovative pressure-assisted seal design ensures tight shut-off while allowing the use of smaller, more economical actuators, fully compliant with ASME B16.34 shut-off standards.
The optional ENVIRO-SEAL packing system features precision-polished stems and live-loading technology, significantly enhancing sealing performance and operational stability.
For demanding applications, the valve can be equipped with corrosion-resistant trim and bolting materials, making it particularly suitable for harsh environments including sour service conditions.
During installation, the valve body self-centers on pipeline flange bolts, greatly simplifying the installation process while ensuring precise alignment.
The carefully engineered sealing design positions retainer screws away from sealing surfaces, completely eliminating potential interference with sealing performance.
Notably, the valve features balanced bi-directional torque characteristics – maintaining consistent opening/closing torque regardless of pressure direction – greatly simplifying actuator selection and system design, making it an ideal choice for critical applications.
