HBS Sequence Valves

About HBS

Since 1967, HBS has been working on their spirit ‘advangarde technology’ in the hydraulic field. Throughout the years HBS has directed their effort to achieve the best results in quality, reliability and development. Their products are successfully utilized all over the world.  

Their Monzambano-based factories cover a surface of 12000 square meters and include the research lab, quality control department and manufacturing department. The company mission is to be more than just manufacturers of hydraulic parts.

HBS Sequence Valves

HBS Sequence Valves are high quality elements that open when an established pressure value is reached, allowing the fluid to pass to another part of the circuit. For this reason, the opening depends upon the existing upstream pressure. The pressure in the circuit that instigates the opening is kept equal to the setting value, when the valve is open. Whenever upstream pressure decreases under the setting pressure value, the valve will close.

Sequence valves are slightly similar to pressure relief valves, since they both operate based on pressure changes. The difference lies in the fact that once the set pressure level is reached, sequence valves have an actuator that diverts the medium to another part of the system to enforce the next command in the programmed sequence.

The basic function of a sequence valve is to control the sequential operation of multiple actuators. HBS Sequence Valves have an actuator that diverts the medium to another part of the system to execute the following command in the programmed sequence. This function is crucial to the performance of many different industrial systems.

Depending on their application, sequence valves go by a few different names: back pressure valve, unloading valve and balance valve.
