A safety relief valve is a pressure relief valve characterized by rapid opening
pop action or by opening generally proportional to the increase in pressure
over the opening pressure. When the pressure increase in the line, this valve
protect the system to discharge the pressure more than over pressure.
Our, KORVAL, CRYOGENIC SAFETY RELIEF VALVE has many
strong point (especially it has a durability for change
and/or transformation) because it use special low material at type
and it¡¯s designed and manufactured by all sorts of rule.
KSC-D L : The large power to small power display one¡¯s ability
-DM for pilot type. It is product with correct operation,
compact size, vacuum breaker, no leakage.
The product have performance of maximum at low pressure.
It has many strong point and it is the one to use on
the ¡±CRYOGENIC TANK¡±.
KSC-SH : The is product of ¡±CONVENTIONAL TYPE¡±. It is the one to design
specially on the disc and a seat (the trim part) for high pressure,
no leakage, minimum back pressure. So the valve can stand on
high durability against impacts and corrosion. |
