Steam Trap

As a Steam Trap Supplier in Dubai, UAE Valves provides high-quality industrial steam traps designed to improve energy efficiency and reliability in steam systems. By automatically discharging condensate and non-condensable gases while retaining live steam, our traps keep heat exchangers, tracing lines, and process loops operating at peak performance with reduced losses and stable pressure control.

How Steam Traps Work

Steam traps distinguish between condensate, steam, and air, opening or closing automatically to remove only what is needed:

• Float Type – a buoyant ball rises with condensate, lifting a lever to open the seat for continuous discharge at near condensate temperature.
• Thermostatic Type – a bimetallic or bellows element expands/contracts with temperature change, opening wide on cold start and closing as steam reaches the trap.
• Thermodynamic Disc Type – uses flash steam dynamics above the disc; it snaps shut under pressure and reopens once equilibrium is restored.
• Inverted Bucket Type – the bucket floats up with steam to shut the valve and sinks with condensate to open it, offering rugged performance and dirt tolerance.

The result is automatic, reliable drainage without wasting live steam.

Benefits of Steam Traps

• Maintains heat transfer efficiency and reduces steam losses
• Prevents water hammer, erosion, and corrosion in steam lines
• Provides rapid air venting during startup for faster warm-up
• Simple mechanisms with minimal moving parts for easy maintenance
• Options available to handle backpressure, fluctuating loads, and dirty service

Types of Steam Traps

• Ball Float Steam Trap – continuous condensate discharge, ideal for process heating and high loads
• Bimetallic Steam Trap – thermostatic element for high-temperature tracing and variable conditions
• Inverted Bucket Steam Trap – robust design with excellent dirt handling and air venting
• Thermodynamic Disc Steam Trap – compact disc type for high-pressure mains and outdoor service
• Thermostatic Balanced Pressure Trap – opens wide on cold start and seals as steam arrives
