Product Overview

A three way ball valve controls and redirects flow between multiple pipelines using a compact quarter-turn design. Commonly available in L-port and T-port configurations, it is ideal for flow diversion or mixing in water treatment, HVAC, chemical, and industrial systems, offering reliable sealing and efficient operation.

Product Features

Flexible flow control with L-port or T-port design for diverting or mixing media
Tight shut-off performance ensured by precision ball and seat design
Quarter-turn operation for fast, low-torque control
Robust materials suitable for water, oil, gas, and chemical applications
