Problems with the pressure relief valve
Thread Content
We are currently dealing with a DN300 self-protecting valve. The manufacturer recommends using a double-acting ball valve equipped with an accumulator, while the client prefers a single-acting valve that does not require an accumulator (the manufacturer claims that such an actuator is too large). Do you think a double-acting valve with an accumulator is better, or a single-acting valve without one?
Of course, a double-acting valve with an accumulator is better; the reason is that, just as manufacturers recommend double-acting valves with accumulators, it is a reasonable choice and the preferred option. Using a single-acting valve actuator is too large and has many disadvantages.
Personally, I think for valves above DN300, double-acting ones are better; single-acting ones are too large in size. Of course, if space permits, a single-acting one can also be used.
Uh, thank you! After communicating with the owner, they also agreed to use a double-acting one.
4# Huagongduzhe: The single-acting type relies on a spring for reset, which makes it relatively reliable. However, for DN300 models, if the torque is high, its size becomes too large.
