Overview
A balance valve is a precision flow control device designed to maintain hydraulic equilibrium in piping networks. Typically constructed from stainless steel or cast iron, these valves adhere to international standards such as ISO 5208 for leakage and pressure ratings.
Application
- HVAC Systems: Balancing water flow in district heating and cooling loops.
- Industrial Process: Regulating fluid distribution in chemical and pharmaceutical plants.
- Water Treatment: Ensuring uniform pressure across filtration stages.
Precautions
- Safety: Install pressure gauges upstream to monitor differential pressure during operation.
- Maintenance: Conduct periodic calibration every six months to prevent drift.
- Replacement: Replace internal seals immediately if leakage exceeds allowable limits.
