The trap contains a float valve mechanism which modulates to discharge condensate continuously at steam temperature, while non-condensible gases are released by a separate internal thermostatic air vent.
In the interests of development and improvement of the product, we reserve the right to change the specification.

Sample SpecificationSteam traps shall be of the mechanical ball float type having cast steel bodies with stainless steel internal parts. The piping connections shall be horizontal in-line, and the body shall incorporate mounting legs with drilled pads. The traps shall have an integral thermostatic air vent. The trap body shall be horizontally split and all internal parts shall be completely serviceable without disturbing the inlet and outlet piping.
InstallationThe trap should be located below and close to the equipment drain point. A pipe-line strainer should be installed ahead of the trap, and full port isolating valves should be placed to permit servicing. The mounting legs should be bolted to a firm horizontal support. Access above the trap must be provided for servicing.Complete installation instructions are given in IMI 2.3041.
MaintenanceThis product can be maintained without disturbing the piping connections. Complete isolation from both supply and return line is required before any servic-ing is performed.
The trap should be disassembled periodically for inspection and cleaning of the valve mechanism and air vent.
Complete installation and maintenance instructions are given in IMI 2.3041, which accompanies the product.
