Temperature SensorThis sensor is temperature proportion type. The sensor part sense the temperature, and the liquid will expands or contracts by the temperature change. It can operate the main shaft stem in the sensor pocket and It’ll make a valve open/close by this working. This item usually used to Temperature Regulating valve by Korval.

● FEATURE AHS-BT : This type is that the temperature control part is on the sensor part and only use liquid. Standard type. AHS-BV : It is possible to set the temperature on the valve and it can free to use based on location of sensing

system establishment. It is liquid only. AHS-CT : It is possible to set the temperature on the valve and it react sensitive , only use air. AHS-CV : It is possible to set the temperature on the valve, it can do accuracy set temperature because of dual

sensor therefore it can cover the temperature change, only use air. Usually it used on place of wide temperature change.

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 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.

KPP-CYThe operate part is balance type. So the influence of back pressure is small and it can control precision by sensitive acting.

KPP-PLThis is cylinder pilot type. So it can operate by small power. That’s why the size of alve is smaller than other type. It can use in this case.
