YARWAY FLOAT AND THERMOSTATIC STEAM TRAPSSLR ASSEMBLY (OPTIONAL)

DESCRIPTION

In siphon drip tubes connected to rotating cylinders or long drain lines a steam pocket may form and so the condensate does not reach the trap. This condition is normally known as steam locking and when Float and Thermostatic steam traps are used it is necessary to prevent the problem.The SLR - Steam Lock Release should be requested to bleed away that steam.All the Float and Thermostatic steam traps can be supplied with the SLR and some can even be supplied with both SLR and air vent.F881, F883 and F884 series can be supplied with air eliminator (standard), with SLR or with both air vent and SLR on request.An internal strainer can also be supplied with the F881, F881HC, F883 and F883HC models.
