The ARI CONA TD Steam Trap with PN63 pressure rating and screwed connections is a compact, highly durable solution for removing condensate and non-condensable gases from steam systems. Operating on the thermodynamic principle, this trap delivers rapid and efficient discharge without allowing live steam to escape, making it ideal for applications where reliability and energy efficiency are key.
Designed for high-pressure environments, the PN63-rated body ensures safe operation in demanding process conditions. The screwed connections offer simple installation and replacement in threaded pipelines, particularly useful in tight or remote areas. With no moving float or lever parts, the CONA TD is exceptionally resistant to water hammer, freezing, and wear — ensuring minimal maintenance and long operational life. This steam trap is perfect for steam tracing lines, main headers, and small heat exchangers across a wide range of industries.

FAQ's
What is the difference between a valve and an actuator?
What types of actuators are available?
The main types of actuators are:
Pneumatic actuators – use compressed air for fast, reliable operation.
Electric actuators – use electrical power for precise control.
Hydraulic actuators – use fluid pressure for high-torque applications.
Each type offers unique advantages depending on the environment, media, and system control needs.
How do I choose the right actuator for my valve?
To select the correct actuator, consider:
Valve type and torque requirement
Power source available (air, electric, or hydraulic)
Operating environment (temperature, humidity, hazardous area)
Control signal type (on/off or modulating)
Matching actuator torque and compatibility with the valve’s ISO mounting ensures reliable performance.
What are the main types of valves used in automation?
The most common valves in automated systems include:
Ball valves – for tight shutoff and quick operation.
Butterfly valves – for larger flow control with compact design.
Globe valves – for precise throttling and flow regulation.
Check valves – to prevent backflow.
Gate valves – for full bore flow isolation.
What’s the difference between a double-acting and spring-return actuator?
Double-acting actuators use air (or power) to both open and close the valve.
Spring-return actuators use air to open (or close) the valve, and a built-in spring to automatically return it to a safe position when power or air is lost — ideal for fail-safe operation.
How often should valves and actuators be serviced?
Regular maintenance intervals depend on operating conditions, but a good rule of thumb is to inspect every 6–12 months.
This includes checking for leaks, lubrication, seal wear, and actuator responsiveness to prevent unexpected downtime.
