Esfahan Steam Equipment - 442 TYPE BALL FLOAT HEAVY DUTY STEAM TRAP

1. 442 TYPE BALL FLOAT HEAVY DUTY STEAM TRAP

Description:
	The 442 type of ball float heavy duty steam trap is designed for using the place where much amount of drain is expected such as heat exchangers, dryers or headers. These traps have simple constructions and reliable operations due to their lever float type, with cast iron bodies. It is available in two models: a- With a manually adjustable air venting needle valve ( Model 442 F ) b- With integral automatic thermostatic air venting facility ( Model 442 FT )

Limiting Conditions :

Body design conditions	PN 10
PMA - Maximum Operating pressure	5 kgf/cm²
TMA - Maximum Operating temperature	150°C

Capacities:

Maximum Continual discharge amount ( m³/ h)

	0.3	0.5	1	2	3	4	5
DN25	1.10	1.75	3.00	4.50	5.60	6.50	7.20
DN32	1.10	1.75	3.00	4.50	5.60	6.50	7.20
DN40	2.10	3.30	5.10	6.60	7.80	8.80	9.50
DN50	2.10	3.30	5.10	6.60	7.80	8.80	9.50

Note: Capacities shown are based on discharge at saturation temperature. In 442- FT, when discharging sub-cooled condensate the air vent provide extra capacity. Under start up conditions the thermostatic air vent will be open, and will provide additional condensate capacity to outlet.

Installation:

The trap should be installed in horizontal pipeline with the direction of flow as indicated by the arrow on the trap body.

How to Order:

Example: DN40 - 422 - FT ball float thermostatic steam trap.
