Frequently Asked Questions

Common questions about valve selection, specifications, and certifications for this industry.

Which industrial valves are commonly used in HVAC systems?

Butterfly valves, ball valves, gate valves, globe valves, check valves and control valves are commonly considered for HVAC systems. Selection depends on pipe size, fluid temperature, operating pressure and whether isolation, reverse-flow prevention or flow regulation is required.

Which valves are suitable for chilled water systems in commercial buildings?

Butterfly valves and ball valves may be considered for isolation, while suitable control valves can regulate chilled water flow. The correct choice depends on pipe diameter, pressure drop, flow rate, temperature and the system's control requirements.

Which valves are used in cooling tower water circulation systems?

Butterfly valves, gate valves and check valves may be used depending on the cooling tower arrangement. Consider water quality, suspended solids, corrosion risk, operating pressure and the required flow capacity when selecting a valve.

How do I choose the right control valve for an HVAC system?

Consider the required flow rate, differential pressure, fluid temperature, control accuracy and actuator requirements. Correct valve sizing and suitable control characteristics help support stable temperature regulation and efficient system operation.

What is the difference between a butterfly valve and a ball valve in HVAC applications?

Butterfly valves are often considered for larger pipe sizes where compact installation is useful. Ball valves provide quarter-turn operation and are commonly used for isolation in suitable applications. The best option depends on pipe size, pressure rating, flow requirements and installation constraints.

Are actuated valves suitable for automated HVAC and building management systems?

Yes. Pneumatic or electric actuated valves can support automated isolation and flow control. Selection should consider the control signal, actuator power supply, operating torque, feedback requirements and compatibility with the building management or control system.

How do I select valves for hot water and heating circulation systems?

Check the maximum operating temperature, system pressure, flow rate, material compatibility and required shut-off performance. Confirm that the valve, seat and seals are rated for the system's operating conditions.

Why are check valves important in HVAC water circulation systems?

Check valves help prevent reverse flow, which can affect pumps and connected equipment. The suitable design depends on flow conditions, pressure drop, installation orientation and the risk of water hammer.
