Three-way ball valve

[Product Use] 

 Q45F type PN16~PN40 T-shaped three-way ball valve is available in T-shaped and L-shaped. The T-shape enables the three orthogonal pipes to connect with each other and cut off the third channel, playing the role of diversion and confluence. The L shape can only connect two pipelines that are orthogonal to each other, and cannot maintain the interconnection of the third pipeline at the same time, and only play the role of distribution. 

 [Product Features] 

 1. The three-way ball valve adopts an integrated structure in structure, with a sealing type of four-sided valve seats, with few flange connections and high reliability. The design is lightweight. 

 2. The three-way ball core is divided into T-shaped and L-shaped, with long service life, large circulation capacity and low resistance. 

 3. The ball valve is divided into two types: single-acting and double-acting. The characteristic of the single-acting type is that once the power source fails, the ball valve will be in the state required by the control system.

Product Application Scope

These devices are suitable for accurately controlling media such as gases, liquids, steam, etc., and maintaining process parameters such as pressure, flow rate, temperature, and liquid level at given values. Especially suitable for work environments where the allowable pressure difference is small and the allowable leakage is also small, and the pressure difference is not significant.
