５．
Selection of Nominal Size
(１)
Select the trap which shows the safety factor 4
～
5 for an actual use. That is, when discharge capacity of 100 kg/h is
needed, it is economical to use the trap which has the performance of 400
～
500 kg/h.
(２)
You must consider back pressure in order to select the discharge capacity because the trap discharge
condensate according to a difference (operating differential pressure) between the inlet pressure and the outlet
pressure (back pressure). For example, when the inlet pressure is 1.0MPa and the outlet pressure is 0.2MPa,
these are the discharge capacity for operating differential pressure of 0.8MPa.
Max. Continuous Discharge Capacity

Installation
6.1 Warning and Caution for Installation
Warning
(
１
)
Plumb in the piping of the outlet side to the safe place where blowing steam condensate can not affect.
※
It is dangerous if fluid blows out.
Caution
（１）
Remove foreign matter and scales from the lines before connecting the valve.
※
Failure to do so may prevent the valve from functioning correctly.
※
Be sure not to make sealing agent or seal tape go into pipe.
（２）
When installing, confirm if the direction of fluid flow matches with inlet and outlet port of the product
respectively.
※
If installed in opposite direction, it will not function as designed.
（３）
Carry out the securing of pipes and the product properly.
※
If exert excessive stress to the valve, it may result in malfunction.
（４）
Do not disassemble the trap unreasonably.
※
Disassembling the trap at your discretion may affect the original performance.
（５）
When installing, secure the space for the maintenance and checking (cleaning of the screen).
※
It is needed to carry out the maintenance and inspection (cleaning of the screen).
