Diaphragm Valves
PROTEGO® Diaphragm Valves function as pressure vacuum relief valves. The flexible diaphragm allows them to work as a dynamic flame arrester which provides
The PROTEGO® LDA-F series of liquid detonation arresters was developed for storage tanks filling and drain lines that are not continuously filled with product and sometimes contain a combustible mixture. T...
The PROTEGO® VN-A-PCPM pilot-operated diaphragm valve is a highly developed valve for pressure and vacuum relief. It is primarily used as a safety device for out-breathing in tanks, containers, and proc...
The PROTEGO® BE/AD end-of-line deflagration flame arrester provides protection against atmospheric deflagrations. The device is usually installed on vent lines of small vessels and plant equipment which ar...
The VD/SV type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent flow performance. Typically, the valve is installed in the in-breathing and out-breathing lines of tanks,...
PROTEGO® Floating Suction Units, FSU, are used in storage tanks with very high purity requirements of the substances, e.g., aviation or fossil fuels. They are designed to ensure that product in a storage t...
The PROTEGO® EH/0S vent cap allows vessels which are not pressurized to vent. This device prevents rain and dirt entering the vent line. The PROTEGO® EH/0S vent cap is not flame transmission pr...
The PROTEGO® BR/TS-80-IIB-P1.6 detonation flame arrester was developed for protecting tankships but can also be used for containers. These devices are especially used on tank ships operating on inland wate...
PROTEGO® air-drying device of types LA or LA/V is used when suction air must be dried for atmospheric venting of storage tanks where only little or no humidity is allowed to get into the tank or the s...
The deflagration-proof and endurance burning-proof P/EB-E type PROTEGO® valve is a highly developed pressure relief valve for large flows with an integrated flame arrester unit that is specifically designe...
