New Pressure and Vacuum Relief Valve for Cryogenic Applications


The new PROTEGO® PM-HF will be launched at the StocExpo!

The PROTEGO® PM-HF pilot-controlled pressure and vacuum relief valve is an advanced development of the PM/F model. The PM-HF now allows pressure settings of up to 15 psi - 1,034 mbar to be made. Its persuasive design features an improved flow efficiency and extreme seal-tight capability. The valve is available in a soft-seating configuration. Minimized product losses and, hence, reduced environmental impact are guaranteed. The valve can be put to service in applications where temperatures as low as -196°C prevail.
The PROTEGO® PM-HF has furnished proof of its excellent performance in extensive endurance tests conducted under overload and in tough climatic conditions.
