PRODUCT INTRODUCTION

A concentric butterfly valve, also known as a centerline butterfly valve, is a quarter-turn rotary valve where the stem axis, disc center, and body center are collinear. It controls flow via 90 rotation of the disc, widely used in water supply, HVAC, chemical, and power industries for low-to-medium pressure (PN16) and ambient temperature (89) applications.

PRODUCT FEATURES

Simple & Compact Design

Small size, light weight (30%60% lighter than gate valves of the same diameter); wafer/lug connection, minimal installation space, multi-orientation installation, easy maintenance.
Low Flow Resistance & Good Regulation

Low flow resistance (0.10.5), full bore flow for energy efficiency; nearly linear flow characteristic with good regulation accuracy.
Reliable Soft Seal

Soft seal (EPDM/NBR/PTFE) for bi-directional bubble-tight shutoff; replaceable seat for long service life; leakage rate meets ANSI B16.104 Class VI.
Flexible Actuation

90 quick open/close with low torque; available with manual, gear, pneumatic, electric actuators.
High Cost-Effectiveness

Low manufacturing and maintenance cost, ideal for large-diameter (DN50DN600) systems.
