All-weather fire retardant atoms valve LTHF-6 type
Introduction
LTHF-6 type all-weather fire retardant atoms valve is the latest product and it integrates fire retardant and atoms valve and the latest structure is the first creation in China.
The petroleum chemical storage rank is the new type safety equipments and the biggest advantages are great performance, light, great performance, small amount of linkage and corrosion resistance and it is easy to maintain. The product can be used for the flash point is lower than 28°C A series oil and flash point is lower than 60°C B series oil as petroleum, crude oil and so on. It can work under 35°C~60°Ctemperature environment.
It can be mainly used for storage tank breath ventilated and fire retardant requirements and it can be installed on the top of storage tank to prevent the damage caused by super pressure and it can reduce the tank medium vapor loss. The all-weather fire retardant atoms valve is made according to the GB5908-97 and SY7511-87 standard.
