When the over press occurred in the line by load change.
This valve operate to keep the pressure in the line and/or protect the piping line from
the damage by over pressure and/or operate By-pass function to keep the primary
pressure in the main line.
It is external type, and an auxiliary power is not required and it can operate under
high
temperature / pressure an/or liquid of high viscosity fluid condision.
KPP-CY : The operate part is balance type. So the influence of back pressure is
small and it can control precision by sensitive acting.
KPP-PL : This is cylinder pilot type. So it can operate by small power.
That¡¯s why the size of valve is smaller than other type.
It can use in this case. |
