Water Valves

Water valves for buses – precise control of the heating circuit

In the heating systems of buses and coaches, where coolant lines can extend for up to a dozen metres, the efficiency of water valves is crucial to system performance. In the water valves category on the Peterbus.pl marketplace, we offer a wide selection of components for controlling coolant flow in 24V systems. Our valves ensure leak-tightness and smooth adjustment, enabling effective heating of the passenger compartment and driver’s cab.

The Peterbus range includes:

• Cable-operated heater valves: Classic mechanical solutions in which the driver physically changes the valve opening using a slider or knob.

• Pneumatic valves: Components that use the bus’s compressed-air system to open or close the water circuit, often used in large heating circuits.

• Manual shut-off valves: Ball and butterfly valves installed in the engine compartment or beneath the floor, used to shut off individual heating sections during servicing or the summer season.

• Three-way and diverter valves: Components that allow the coolant flow to be redirected between different circuits (e.g. engine – unit – heaters).

• Dedicated parts for specific brands: Water valves compatible with VDL Bova Futura, Mercedes-Benz, Setra, MAN and Scania.

Our water valves mainly come from dismantled original vehicles in good working order and are rigorously tested for pressure tightness and unobstructed flow. By choosing an original used part from our range, you can be sure that the valve body and port diameters will fit the factory hoses perfectly, eliminating the risk of coolant leaks.

A sticking valve, no response to temperature adjustment or visible glycol leaks are signs that immediate replacement is required. A faulty valve can cause air to enter the system or lead to overheating of the auxiliary heating unit. Peterbus experts will help you select the right valve based on the connection diameter or OEM number. Choose proven hydraulic solutions from Peterbus.
