Water-oil heat exchangers, shell and tube type, permit to cool the heat on hydraulic plants. They operate on the return line of the main hydraulic circuit, or a separate circuit, dedicated to cooling. Heat exchangers, designed to work in hydraulic systems with mineral oil or synthetic fluids, having similar lubricating characteristics.

Bourdon-tube pressure gauge with liquid filling, in stainless steel construction with vibration and shock resistant features.

The isolator needle valves used for protection of the pressure gauge, they have the double function of dampening the pressure surge, during the opening, and entirely isolating the pressure gauge. Rotating swivel nut allows accurate pressure gauge's orientation. The sealing, inserted in the nut, prevents any drawing between the connection and the gauge.
