PROTEGO® Emergency Pressure Relief Valves (available with CMS Pumps) are used when extremely high venting rates are required due to fire on the outer surface.
Tank protection is available via 3 products PROTEGO® VD/SV-PA Pressure and Vacuum Relief Valve, PROTEGO® ZM‑R Nitrogen Control Valve and PROTEGO® ER-V-LP Emergency Relief Valve
Types
The VD/SV -PA(L) type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent flow performance. Typically the valve is installed in the in- and outbreathing lines of tanks, vessels and process apparatus to protect against unallowable high and low pressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to set vacuum. The product vapors can be discharged through a collective line connected to the line flange on the pressure side.
Pressure and Vacuum Relief Valve with pipe-away connection
The PROTEGO® blanketing valve type ZM-R is a highly developed low pressure reducing valve. This valve is typically used to inert or blanket tanks, vessels or other process systems with nitrogen or other blanketing gases by controlling the tank pressure to its desired value.
High nitrogen or blanketing gas supply pressures up to 16 bar / 232 psi are safely reduced down to only a few mbar / inch W.C..
Blanketing Valve low pressure reducing valve
The PROTEGO® Type ER-V-LP valve is a sophisticated pressure relief valve for applications in which a high flow efficiency is of the essence. It is primarily used as an emergency pressure relief valve on storage tanks, vessels, silos, and process engineering equipment.
