Made in Japan
Since its founding over a half century ago, TLV’s goal has been to produce dependable, long-lasting steam traps. One early outstanding success was the A3, a thermodynamic steam trap offering an amazing 10 times the durability of previous products. Behind the A3 was the concept of the “Trouble Less Valve”, from which the company name originated. From this solid foundation, the line of products and services has expanded until now, more than 50 years later, TLV has become a Steam Specialist Company – a recognized leader in the steam-engineering field.

THERMODYNAMIC STEAM TRAPS
THERMODYNAMIC STEAM TRAPS
Thermodynamic Steam Traps are also known as Disc Traps. They are equipped with a bimetal air vent ring which holds the disc away from its seat during start-up until air and cold condensate have been discharged. Hot condensate expands the bimetal and frees the disc for normal operation. The trap closes when flash steam forms under the disc and creates a low pressure region there which sucks it on to the seat. Air or steam jackets insulating the pressure chamber reduce the radiant heat losses to the environment. This prevents no-load actuation and ensures steam tight operation and durability.

“FREE FLOAT” STEAM TRAPS
“FREE FLOAT” STEAM TRAPS
This unique design, brilliant in its simplicity, is typical of TLV-products. The only moving part in this type of steam trap is the stainless steel float which is free to rotate in any plane. This gives an infinite number of seating positions, reducing wear to a minimum. There are no complicated mechanical linkages. Condensate is discharged immediately as it reaches the trap (no back-up). An inbuilt thermal high capacity air vent ensures the quick start-up of processes.

Sight Glass for Steam, Air and Water
Sight Glass for Steam, Air and Water
Compact lightweight sight glass for installation at the outlet side of steam traps to monitor trap performance and to check for steam leakage. Also recommended for checking the line flow of air and water. Suitable for small-to-large flow rates.
TLV Sight Glass have clear sighting through self-polishing, heat-resistant glass with a Moving Ball indicating the flow status.
Pocket TRAPMAN Diagnostic Tool
Pocket TRAPMAN Diagnostic Tool
Compact Pocket Size instrument employing ultrasonic and temperature detection for steam trap, valve and bearing basic operational judgements.

• Compact and easy to use
• Simultaneously measures vibration and surface temperature
• Analog and digital display plus scaled audio function assist operation assessment
• Quickly makes basic judgments for steam traps and valves to help identify where repairs or replacements may be necessary
• dB is displayed for bearing inspection to help diagnose operational status
• Band-pass filter eliminates misleading background noise, focusing on high frequencies for improved accuracy over conventional ultrasonic detectors
• Stores the results of up to 100 trap/valve and 100 bearing inspections in internal memory.
PUMP TRAPS AND CONDENSATE RETURN PUMPS
PUMP TRAPS AND CONDENSATE RETURN PUMPS
TLV Pump Traps and Condensate Return Pumps are designed for complete condensate drainage and recovery preventing “stalling” heat exchangers, temperature swings, water hammer and corrosion. Pump Traps and “Steam driven” Condensate Return Pumps are ideal for hazardous areas (operates purely mechanically, no electricity needed). They ensure a safe and economical operation of steam plants.

Thermostatic Air Vent for Steam
Thermostatic Air Vent for Steam
Compact all stainless steel air vent with “fail open” feature for steam, for vertical installation.

• Vents air automatically until close-to-steam temperature
• Compact, yet with high capacity
• Reacts immediately to changes in operating conditions
• Withstands superheat and waterhammer
• Easy to maintain and easy to clean
• Hardened SS valve seat
• Tight shut-off
Compact Reducing Station COSPECT
Compact Reducing Station COSPECT
TLV Process Steam Controls and Systems have been developed especially for the heat carrier steam. The COS-Series design takes into account that process steam for heating is in reality generally not available as 100% saturated steam, but is to a greater or lesser degree supplied as wet steam.

Special features of the Compact Pressure Reducing Station COSPECT are ease of maintenance, internal sensing line, wide pressure adjustment range and compact design.

Special components:
- Specially designed shock-absorbing spherical piston accurately maintains the set pressure and reacts quickly to primary pressure or flow fluctuations
- Super cyclonical effects separator for dry steam: separation efficiency as high as 98 %
- “Free Float” steam trap for continuous, smooth condensate discharge

Vortex Flowmeter for gas, Steam and Liquids
Vortex Flowmeter for gas, Steam and Liquids
High performance vortex flowmeter with robust sensor for highly accurate volume or mass flow measurements of gasses, liquids, saturated and superheated steam.

• DSC (Differential Switched Capacitance) sensor offers a wide measuring range, with a high resistance to thermal shock, vibration and water hammer
• Integrated flow computer calculates mass flow from measured volume flow and temperature variables.
• Capable of simultaneous pulse (interval) and analog (instantaneous) output
• Requires no maintenance, has no moving parts, and experiences no zero point drift
• Low pressure drop through body

TRAPMAN Steam Trap Management System
TRAPMAN Steam Trap Management System
Automatic High Precision Judgment of Steam Trap Operation Status

The diagnostic instrument compares ultrasonic and temperature readings with laboratory data to determine whether trap operation is normal or failed and, where indicated by the judgment, the estimated amount of steam leakage is calculated.
Steam trap malfunctions can be discovered soon after they occur, which contributes to the stable operation of the steam equipment.

- Includes Comparison Data for Thousands of Traps Brands and Models

- Compact and Easy to use

- Regular inspections with TRAPMAN ensure that energy efficiency of a steam network are continuously optimal.
