TIVAL mechanical pressure switch FF 4 GL
TIVAL FF4 GL pressure switch - approved for shipbuilding and offshore use
The TIVAL FF4 GL is a high-performance pressure switch with GL approval (Germanischer Lloyd) for use in shipbuilding and in offshore applications.
It is optionally available with a Perbunan diaphragm and silumin pressure connection for pressure ranges from 0.11 to 32 bar or with a plastic piston and stainless steel pressure connection for 4 to 250 bar. The pressure connection H (G 3/8″ female thread, DIN 1725/2) complies with the VDE 0660, IEC 337-1 and IEC 553-1 standards. Thanks to the marine cable gland and the additional earthing terminal, the FF4 GL offers maximum safety and reliability under maritime conditions - e.g. for starter compressors or in other marine systems. It has a large connection compartment, separate adjustment of the upper and lower switching points, an easy-to-read scale and high repeat accuracy.
