Three-way ball valve

The oxygen specific shut-off valve is made of high-quality silicon brass or stainless steel casting, which has the advantages of high mechanical strength, wear resistance, and good safety. Used on oxygen pipelines, it has effective explosion-proof and flame-retardant properties, eliminating unsafe factors on oxygen pipelines.

I. Overview of the L-Type Three-Way Stainless Steel Ball Valve Product;

Our company manufactures Q44F and Q45F three-way ball valves, which are available in L-shaped and T-shaped designs. The L-shaped (Q44F) three-way ball valve is used for switching the flow direction of media, enabling connection between two mutually perpendicular channels. Meanwhile, the T-shaped (Q45F) three-way ball valve is designed for dividing, merging, and redirecting media flows. Specifically, the T-shaped valve allows all three channels to remain interconnected, or it can connect any two of the channels while isolating the third.

Features:

1. The three-way ball valve features an integrated design with a four-seal-seat configuration, minimizing flange connections while ensuring high reliability and achieving lightweight construction.

2. Three-way ball cores come in T-shaped and L-shaped designs, offering a long service life, high flow capacity, and low resistance.

3. Ball valves are classified into two types based on their actuation method: single-acting and double-acting. A single-acting valve is designed so that, in the event of a power failure, it will automatically return to the position required by the control system.

Applicable scenarios:

The three-way ball valves Q44F and Q45F are widely suitable for a variety of media, including water, oil, gas, nitric acid, and acetic acid.
