Pressure relief valve - Import export

As emergency venting device for installation on storage tanks with a VRV to protect against hazardous excess pressure but minimize the loss of gas/vapours. Also suitable as replacement of a manhole. This device does not protect against the hazard of explosion or stabilized burning.

Application as installation explosion-proof and endurance burning proof for certain flammable liquids of the explosion group IIA with a maximum experimental safe gap (MESG) > 0.9 mm and a maximum operating temperature of 60 °C. As venting and breather device for fixed roof tanks to prevent inadmissible pressure and vacuum and to minimize gas losses by variable pressure setting of the weight-loaded and/or spring-loaded valve devices. Installation of an explosion-proof condensate drain device is possible.

As end-of-line armature, for venting apertures on tank installations. Used mainly as venting and breather device for fixed roof tanks. Used to prevent inadmissible pressure and vacuum and to minimize unwelcome gas losses or inadmissible emissions respectively. The housing is mounted perpendicularly on a tank roof. The product vapours can be discharged through a collective line into the atmosphere connected to the line flange on the pressure side.

Application as inline armature with venting and breather valve function for vessels. Preferably used for installation in pipes.

Application as end-of-line armature for venting and breathing of tanks. Tested and approved against atmospheric deflagrations for all materials of the explosion group IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65 mm and a maximum operating temperature of 60 °C. Vertical mounting (for tank roofs) with an integrated elbow as an option.

As end-of-line armature, for venting apertures on tank installations. Used mainly as venting and breather device for fixed roof tanks. Used to prevent inadmissible pressure and vacuum and to minimize unwelcome gas losses or inadmissible emissions respectively. The housing is mounted perpendicularly on a tank roof.

Proof for products of explosion group IIA with a maximum experimental safe gap (MESG) > 0.9 mm and a maximum operating temperature of 60 °C. Mainly used as equipment of fixed roof tanks for venting and inbreathing to prevent undue pressure resp. vacuum and undesired losses of vaporization, respectively undue emissions. Installation on top of storage vessels. Available with an explosion and endurance burning proofed condensate drain device.

Application as inline armature with venting and breather valve function for vessels, used preferably for installations in pipes. The exhaust air is carried away via a pipe. The ventilation is also effected via a pipe, which is preferably used to carry inert gas. Functions the same as KITO® VD/o3-… (type sheet F 18 N).
