77000042 BW100AC Brake Hydraulic Valve Assembly

Product Introduction:

The Brake Hydraulic Valve of the Bomag roller is a key electric control component of the hydraulic braking system. Its core function is to receive operation instructions or controller signals, and realize the tight-loose switch of the brake by controlling the on-off and flow direction of hydraulic oil. It locks the brake with spring force in normal state; when powered on, it connects the oil circuit, and the hydraulic thrust pushes open the brake pads to release the brake; when powered off, it cuts off the oil circuit and drains oil to quickly trigger the brake. This valve adapts to working braking, parking braking and emergency braking scenarios, and can link with emergency buttons and PLC systems. It can respond quickly to ensure safety in case of failure, and also has a dust-resistant and vibration-resistant protective design. It is a core part to ensure the safety of equipment start-stop and operation reliability.

What are the core functions of this Brake Hydraulic Valve?

The core functions of this Brake Hydraulic Valve are as follows: It receives operation signals or controller commands to control the on-off and flow direction of hydraulic oil, thus switching the brake between tight (braking) and loose (releasing) states. In normal state, it keeps the brake locked with spring force. When powered, it opens the oil path, using hydraulic pressure to release the brake; when power is off, it cuts off the oil path and drains oil to quickly start braking. It works for working braking, parking braking and emergency braking, and can link with emergency buttons and PLC systems, responding fast to ensure safety in case of faults. Its dust-resistant and vibration-resistant design also helps maintain reliable operation.
