| 真空负压安全阀,TFA72W不锈钢安全阀简介 | |||
| 真空负压安全阀,TFA72W不锈钢安全阀适用于温度≤200℃的负压系统,当容器内负压超过允许值时,该阀自动开启,吸入空气; | |||
| tive pressure system with temperature 200 . When the netative pressure in the container exceeds the allowable value, the valve will open automatically and absorbs air When the netative pressure in the container reaches the allowable value, the valve will close automatically so as to protect the equipment and the system. It is to be installed in normal non-negative pressure systems. When the discharge valve of the container and system has not opened, which produces the negative pressure, this valve will open TFA72W is applicable in nega-automatically. | |||
