Applied in automatic and remote control installations as flow control elements to adjust flow of liquids and gases. Type Z3M is designed to mix two streams of medium, whereas type Z3R is designed to split one stream into two.
Recommended for application in city-heating and HVAC systems, as well as many branches of industry. They can be delivered with P/R actuators (basic option) or with P1/R1; P3/R3 actuators (upon request) electric actuators, manual drive type 20 or with no drives.
We can adjust the control valve to match your individual needs.
