Product Features
THERMOSTATIC STEAM TRAP

NST-TKF21 with the welded Stainless Steel Bellows adjusts itself over entire operating pressure range. This element discharges the condensate at approximately 10º C - 20º C below steam saturation temperature and is also resistant to water hammer.

INSTALLATION

Traps should be installed in easily accessible position and location for servicing. The maximum differential pressure stamped on product name plate must be higher than the maximum differential pressure across the trap. 

1.Pitch all horizontal inlet lines towards the stream trap to help eliminate potential water hammer problems.

2.A dirt pocket and strainer (with blow down) should always be provided before trap.

3.Union fittings or flange connection and shut off valves should be installed on both sides of trap for ease of servicing and trap testing.

4.Install a test valve in outlet pipe and cap it. This allows trap to be tested. 

5.Blowdown piping using full steam pressure for (5) five minutes prior to service. This cleaning process will remove debris from piping.

6.Perform maintenance and cleaning 2/3 days after startup until system is clean. Then perform maintenance every 6/12 months in normal operation.

MAINTENANCE

With regular check and proper maintenance you get optimum performance and a long life service from our product. The mechanism should be inspected periodically and all dirt should be removed from working parts. Worn parts must be replaced. Always renew the gasket whenever you disassemble the steam trap.
