PRODUCT INTRODUCTION

Hard-seal butterfly valve (metal hard-seal butterfly valve) is a high-performance butterfly valve with metal-to-metal/hard composite sealing pairs. It mostly adopts a triple eccentric structure, achieving reliable sealing via precision-machined metal sealing surfaces. It overcomes the limitations of soft-seal butterfly valves in high temperature, high pressure, and wear resistance, and is widely used in harsh conditions like high-temperature steam, oil, and particle-laden media.

PRODUCT FEATURES

Metal-to-Metal Sealing

Sealing surfaces hardfaced with STL, nickel-based/cobalt-based alloys (HRC55-62), precision-ground with fit 95%.
Triple Eccentric Structure

Three offsets of stem, disc, and sealing surface; rolling friction during operation, minimal seal wear.
Wide Temperature and Pressure Range

Suitable for -196 to 650, pressure rating PN16~PN420, ideal for high-temperature and high-pressure applications.
High Hardness and Corrosion Resistance

High hardness sealing surfaces, resistant to particle erosion and chemical corrosion, much longer service life than soft-seal valves.
Bubble-Tight Zero Leakage

Bi-directional sealing, bubble-tight zero leakage, self-tightening as closed, compliant with API 607 fire-safe standard.
Easy Operation and High Flow Capacity

Easy operation, low flow resistance; large-bore discs use truss structure for high strength and large flow area.
Easy Maintenance

Sealing rings/seat replaceable on-site without full valve disassembly, reducing maintenance cost.
Multiple Actuation Options

Available with manual, gear, pneumatic, electric, and hydraulic actuators to meet various automation requirements.
