Castel introduce the new straight check valves "W" series, perfect for applications in refrigeration and air conditioning systems, installable on the liquid line, the suction line or, most appropriately, on the discharge line, affected by the high temperature of the refrigerant fluid.
The new series "W" can be installed in systems with refrigerants HCFC, HFC, HFO, HC and C02.

The principal new developments are laser welding of the body (fig.1), to ensure better external seal, and the laser marking on the brass body of the valve about part number, production batch, Ps and Ts values, allowing the identification and traceability of the product.
