BRAKE SYSTEMS INC WM147BC Part Description
Manufacturer
WM147BC is a normally closed, three-way directional relay valve. A pilot pressure of 65–85 PSI must be applied to the WM147BC’s control port before the valve will open to allow supply pressure to flow to its outlet. The WM147BC will close and exhaust down-stream pressure to atmosphere when pressure at its control port descends to 65–50 PSI.
