Product Overview
HVAC Valves are essential components in any heating, ventilation, and air conditioning system, responsible for controlling the flow, pressure, and direction of water, steam, or other fluids circulating throughout the system. From isolating sections of piping for maintenance to modulating flow rates for precise temperature control, valves play a critical role in ensuring system efficiency, safety, and reliability.
Our HVAC valve offerings cover a comprehensive range of manual and automated valves, supported by a selection of instrumentation for system monitoring and control. All valves are designed and manufactured to meet the stringent demands of HVAC applications - including chilled water, hot water, cooling water, steam, and condensate systems - ensuring long service life, dependable operation, and minimal maintenance.
Precise Hydronic Balancing – Save Up to 20% Energy
As one of the most complex systems in a building, cooling systems can continuously improve building energy efficiency when operating at optimal performance.
A cooling system equipped with thermostatic control valves and hydronic balancing valves can save up to 20% in energy consumption. Moreover, stable water system control enhances occupant comfort - reaching and maintaining desired room temperatures more quickly. With our modular hydronic balancing solutions, you can transform your entire building into an efficient, reliable, and flexible system.
Common Valve Types by Function
Isolation Valves (On/Off Control)
Gate Valves
Provide straight-through flow with minimal pressure drop, ideal for fully open or fully closed service in chilled and hot water systems.
Ball Valves
Quarter-turn operation with excellent sealing and minimal pressure loss, suitable for isolation in HVAC piping systems.
Butterfly Valves
Lightweight, compact, and cost-effective, commonly used for on/off control in large-diameter chilled and cooling water systems.
Diaphragm Valves
Provide bubble-tight sealing, suitable for applications with strict leak-tightness requirements, such as chemical dosing lines in water treatment systems.
Control Valves (Modulating Flow)
Globe Valves
Offer precise flow control with adjustable regulation, ideal for modulating water flow to coils and heat exchangers in HVAC systems.
2-Way & 3-Way Control Valves
Used to regulate flow in chilled water and hot water circuits, providing accurate temperature control for AHUs and FCUs.
Pressure Independent Control Valves
Maintain stable flow regardless of system pressure fluctuations, ensuring consistent performance in variable flow systems.
Balancing Valves
Manual Balancing Valves
Provide static balancing to ensure proper water distribution across all terminal units in a hydronic system.
Dynamic Balancing Valves
Automatically maintain design flow rates under varying system pressure conditions, ensuring optimal system performance.
Safety & Special-Purpose Valves
Pressure Relief Valves
Protect the system from overpressure conditions, preventing damage to equipment and piping.
Check Valves
Prevent backflow, protecting pumps and system components from reverse flow damage.
Strainers
Remove debris and sediment from the system, protecting pumps, valves, and other equipment from damage.
Air Vent Valves
Automatically release trapped air from the system, preventing air pockets that can reduce system efficiency and cause noise.
