Hgh Performance Butterfly Valve is an innovative double offset design product with advanced world-leading technology. This butterfly valve has a unique structure with ultra-reliable sealing performance, wide working conditions, and low operation torque.
Specifications of High Performance Butterfly Valves
The resilient seat design of ZECO high-performance butterfly valve is designed to provide a more optimized solution for the field with wear-out and low torque requirements, and to easily replace the seat after seat damage without the need for special tools;
ZECO high-performance butterfly valve is equipped with composite bearings on the stem above and below the disc. The composite bearings have PTFE and epoxy filament winding, which reduces torque in the switch and reduces wear between the stem and the body for longer service;
ZECO high-performance butterfly valve’s fireproof bi-directional resilient seat design ensures zero leakage of the valve during normal operation. The metal-to-metal seal of the seat after fire meets or exceeds the industry “fire safety” specification;
The gland flange design of ZECO high-performance butterfly valve applies load against the packing gland to prevent external leakage. Fully adjustable.
ISO 5211 top plate for direct mounting of a wide range of actuators, handles, and gears
Adjustable stem packing features pull down gland with easy access without removal of the actuator
Tangential wedge pins are offset from the center of the stem putting them in compression rather than shear
Disc stop is designed to prevent disc rotation in the wrong direction and potential seat damage
Retainer clip provides blow-out proof stem
Live-loaded stem seal system by a set of Belleville springs. Rocker shaped gland bridge compensates for uneven adjustment of gland bolts
“Bear-X” bearing has excellent thermal, chemical, and wear resistance
One piece body with extended neck
Self-energizing flexible lip seal soft seat design. Two points of contact on fire-safe metal seat design
Applications of High Performance Butterfly Valve
High Performance Butterfly Valves are specially designed for applications in the chemical, hydrocarbon processing, pulp & paper, water & wastewater, and HVAC industries worldwide. The valve was designed with an understanding that process industries need products that provide exceptional performance while reducing the total cost of ownership.
