Most Terex control valve installed in the cab switch on the dashboard, Terex control valve connecting the loader chassis switch between the gas transmission system, the normal application of Terex control valve switch, traffic safety for the protection of the loader, extended machine life and enhance economic efficiency is very important.
Terex control valve switch is connected or cut off the dual function of gas pipeline leading to the transmission brake control valve on the gas line between the Terex control valve. When traveling on level ground or loader operations, should be Terex control valve switch to "ON 'position. Thus, when the tread brake valve under the gas pedal, the gas turned on; from the air brake pressure over gas (0.45 ~ 0.65MPa), part of the brake master cylinder to the liquid, the other through the cut-off valve switch, enter the pay-speed control valve Terex control valve on the control of the cylinder; cylinder piston to overcome the return spring tension, to promote the Terex control valve stem forward, cutting shift circuit, the high pressure oil sump cited backcross cruise control, shift clutch friction plate separation, the transmission will cut off their own power. brake cut off the power transmission system, it can enable mechanical brake is sensitive, good effect, but also saves fuel.
Application part:
When driving on the ramp or loader operations, should be Terex control valve switch to "off" position. Thus, when the tread brake valve under the gas pedal, because gas cut off from the air over the part of the brake pressure gas, can not switch off the valve, Terex control valve control cylinder piston can not move forward, cut off the valve stem fixed and shift the normal oil, clutch work remains status, delivery speed detector hanging from stalls. braking power transmission system can not be cut off when the brake pedal when relaxed, machinery can be quickly started; when parking in the ramp during the machine can effectively prevent occurrence of the phenomenon of slip slope to protect the driving or operating machinery safety.
