Description of High-Performance Butterfly Valve:

ZECO is one of the world’s leading manufacturers of high-performance butterfly valves. Based on many years of research, development, and field experience, the ZECO design is superior to, and more versatile than, the high-performance butterfly valve design offered by other manufacturers. ZECO products are produced under ISO9001 quality management system. Every production process has corresponding management system documents and management system procedures to ensure that each valve meets or exceeds international standards or user requirements. ZECO high-performance butterfly valve is a mature product for oil and gas processing, heating, power, water and waste water treatment industries, especially suitable for harsh environments and industrial applications requiring rated pressure and temperature rating. ZECO has professional manufacturing experience in high-performance butterfly valves, with outstanding quality records and fast delivery times in the industries it serves.


Features of High Performance Butterfly Valve:

1. 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;

2. 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;

3. 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;

4. The gland flange design of ZECO high-performance butterfly valve applies load against packing gland to prevent external leakage. Fully adjustable.
