Air filtering and pressure relief valve
QTY series air filter pressure reducing valve is used in the general starting control system and general pneumatic pipeline need to maintain a certain air pressure conditions. It directly relies on the handle to control the pressure regulating spring to adjust the output pressure, which can realize stepless pressure regulating within the specified pressure regulating range and keep stable at the set value. When the downstream pressure (outlet pressure) of the air reducing valve exceeds the set pressure, the relief valve begins to overflow, so this series of products shall not be used directly for harmful gases that are not allowed to spill into the air. The balanced intake valve is used, so the input pressure changes in the range of higher than the set pressure have little effect on the output pressure.
