Product Introduction

Flanged ball valves are quarter-turn rotary valves offering tight shutoff, high flow capacity, low pressure drop, simple construction, easy maintenance, and long service life. The full-bore design passes media with near-zero flow loss.
Available in on/off and modulating configurations, they are built for applications requiring bubble-tight isolation. They handle gas, liquid, steam, wastewater, and fibrous media, and serve oil & gas, chemical, metallurgy, light industry, pulp & paper, power, and refrigeration.

Driven by an electric actuator, the ball rotates 90° between open and closed positions. Compared with gate and globe valves, they are more compact and lighter, simplifying pipeline installation.

Features

Bubble-tight shutoff — Dual-seat spherical sealing delivers zero-leakage performance for leak-free media containment.
Wear-resistant, long service life — PTFE seats are self-lubricating and low-friction against the ball, extending service life.
Flexible flow control — Ball ports are offered in rectangular, V-port, and O-port configurations to match different control requirements.
