Description
When over pressure occurred in the line by load change. This valve operates to keep the pressure in the line and/or protect the piping line from damage and/or operate By-pass function to keep the primary pressure in the main line. It is external sensing type, and an auxiliary power is not required and it can operate under high temperature / pressure an/or liquid of high viscosity.
TPP-CY
The operate part is balance type. So the influence of back pressure is small and it can control precision by sensitive acting.
TPP-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.
