Product Description

Three-way control valves are used in scenarios where three interconnected pipes need to be regulated, and there are two types: confluence (HMT) and divergence (HDT).
When the nominal diameter and pressure difference are small, confluence valves can be used in divergence applications. However, for divergence scenarios where the nominal diameter is larger than 80mm and the pressure difference is large, only divergence valves can be used.

Remarks: 1.The numbers in the dark boxes indicate the standard specification actuators matched with the valve. 2.The numbers in parentheses refer to the pressure difference in divergence scenarios, and the rest are the same for both confluence and divergence scenarios.
