Frequently Asked Questions and Explanations
Please tell me the difference between the head type and the full volume type. (Answer details include a video)
There is a difference in the amount of blowout between the lift type and the total amount type. Either one can be used as long as the required amount of blowout is satisfied.
What is the purpose of the safety valve lever? (There is a video in the answer details)
This is to check if the safety valve can be operated and if there is any abnormality (sticking). (Operate when the pressure on the inlet side is 75% or more of the set pressure.)
Please tell me how to select the safety valve with lever and without lever.
As a general rule, select no lever (sealed type) for fluids that adversely affect the surroundings when the safety valve operates, such as flammable / toxic and liquid. If it is necessary to check the operation of the safety valve by operating the lever, select the one with a lever.
