Product Overview

The Worm Gear Operated Wafer Triple Offset Butterfly Valve is designed to offer exceptional sealing performance and durability in a variety of industrial applications. Featuring a triple offset design, this valve ensures minimal wear on the sealing surfaces, providing a tight and long-lasting seal. The worm gear actuator allows for precise control, offering smooth operation even in demanding environments. Its wafer-style body provides ease of installation and maintenance, while the triple offset design significantly reduces torque requirements, making it suitable for high-pressure and high-temperature systems.

Product Features

The butterfly valve features a three-eccentric sealing design, ensuring minimal wear between the valve seat and disc, and providing a tighter seal.
The seal ring is made from stainless steel, combining metal sealing with flexible double sealing advantages, offering excellent sealing performance and corrosion resistance at both high and low temperatures, along with a long service life.
The disc’s sealing surface is welded with a cobalt-based hard alloy, providing wear-resistant properties and extending its lifespan.
The large-frame butterfly plate structure offers high strength, a larger flow area, and reduced flow resistance.
This folder-type hard-sealed butterfly valve provides bidirectional sealing, allowing installation regardless of media flow direction or available space, making it versatile for any installation orientation.
The actuator supports multi-position installation (90° or 180° rotation), making it user-friendly and adaptable.
