The QR-1C™ valve is generally mounted on the axle and serves two spring OPERATION When a brake application is made, air pressure enters the supply port; the diaphragm moves down, sealing the exhaust. In its standard con fi guration the valve is designed to deliver within 1 psi of control pressure to the controlled device; however, for special applications the valve is available with greater differential or zero hysteresis. Air flows into the emergency port of the spring brakes from the QR-1C™ valve delivery ports. Also for: Qr-1c. At the same time, air pressure forces the edges of the diaphragm down and air flows out the delivery port. It is mounted close to the chambers it serves. The double check valve prevents a service and emergency brake application from occurring simultaneously. The double check valve prevents a service and emergency brake application from occurring simultaneously . When a brake application is made, air pressure enters the brake valve port; the diaphragm moves down, sealing the exhaust.
