This angle-type pressure relief valve with double lever and weights offers precise protection against overpressure in the case of low set pressures. This is a versatile alternative if the system to be protected does not fall under PED and a compact version is not necessary. The set pressure can be very easily adjusted by the user.
2018-5-1 · The valve provides double isolation from pressure at both ends of the valve. A DIB valve however cannot relieve body cavity pressure past the seats meaning its seats are not self-relieving. When using a DIB valve then an external relief system is needed to relieve pressure build-up.
