Product Overview
Matrix Industrial Traders Motorized 2-Way Modulating Control Valves deliver fine-tuned proportional control for hydronic heating and cooling systems. Built with equal percentage flow characteristics, this assembly provides stable fluid management across variable load conditions, preventing system hunting and optimizing chiller efficiency.
Key Features
- Equal Percentage Flow Characteristic: Ensures smooth, linear temperature regulation in HVAC loops.
- High Close-Off Pressure Rating: Tight shutoff prevents energy waste and unwanted bypass flow.
- Universal Control Input: Supports 0(2)-10V DC and 4-20mA modulating control signals.
- Manual Override Mechanism: Allows manual operation during maintenance or power interruptions.
- Low Stem Friction Sealing: Dual self-adjusting PTFE V-rings for maintenance-free durability.
