Steam Trap Station with Test Valves

Steam will automatically shut down as ambient temperatures rise above product solidification temperature. Select self acting temperature control for number of tracer lines.

To Drain

To drain during supervised startup or during shutdown

Steam is uniformly distributed to tracers by forged steel manifold with integral pis ton valves. After supplying heat to tracer lines, condensate is collected in fabricated manifold preassembled with steam trap stations. Three-way test valves allow for startup purging, checking of lines for blockage, isolation of trap for main tenance, and visual testing of steam trap operation. Condensate manifold has an internal siphon pipe to reduce waterhammer and provide freeze protection.
