Pressure controlled take off for air-brake valve - has screw fitting for optional addition to standard air-brake valve

摘要

The pressure control valve for an air brake is fitted with a side duct normally closed by a hollow stud complete with non return valve. This allows the garage to fill the brake system with a control pressure for brake checks. The ducts also allows the fitting of an automatic pressure control for the tyres. The pressure control valve is fitted as a universal unit and can be uprated to include the tyre pressure control facility as an optional extra.
