Product catalog summary
Introduction
Taloar Changzhou's document on Fluid Systems for 2023 focuses on differential pressure control valves used in HVAC systems, particularly in variable flow systems. These valves maintain a constant differential pressure, enhancing system efficiency and control accuracy while reducing noise and energy consumption.
Specifications
The document details two main products: the PC320 and PC1000 differential pressure control valves. The PC320 is made of bronze, suitable for pressures up to 350 PSI, and operates within a temperature range of -10°C to 120°C. The PC1000, made of ductile iron, supports pressures up to 400 Kpa and similar temperature ranges. Both models feature a low-resistance Y-shaped structure and do not require external power sources.
Applications
These valves are used to stabilize differential pressure in HVAC systems, preventing issues like noise and system imbalance. They simplify hydraulic balance commissioning and allow for regional balance without the need for re-commissioning when system changes occur.
Installation Recommendations
Proper installation requires sufficient space for maintenance and a strainer to prevent blockages. The document emphasizes aligning flow direction with the valve's arrows and ensuring adequate straight pipe lengths before and after the valve.
Commissioning and Adjustment
Valves are pre-set to initial differential pressure values and can be adjusted using a hand wheel. The document provides a table for adjusting pressure ranges based on valve size.
Conclusion
Taloar's differential pressure control valves are designed to enhance the performance and reliability of HVAC systems, offering precise control and energy efficiency. The company emphasizes quality and user satisfaction in its product offerings.

Taloar Changzhou FLUID SYSTEMS, 2023 Recommendations on Installation 1. The valves are designed with multiple external copper parts, please handle with care during transportation or installation to prevent the valves failing to operate due to damage in the pipes. Large-sized valves are designed with lifting screw holes (2%"~10" valves designed with two M12 screw holes on their shells). 2. All valve bodies are casted with flow direction arrows. During installation, please ensure the medium flow directions in pipeline systems are consistent with the directions of the arrows. 3. Each valve is affixed...
