Detail
23QT-L15 two-position, three-position normal air control valve is a new type of air control valve, is the original QF506 dual-use relay modified generation of products.
23QTL15 two-position three-way normal air control valve is composed of valve body, valve stem, valve cover, piston, lower cover, seal, spring and other parts.
The valve has a gas source port (P), an output port (A), an exhaust port (O) and a control port (K). The valve is in a constant state with no control gas, with the gas source port connected to the output port. In the state of control air, the piston and spool in the valve move forward to cut off the passage between the air source port and the output port, while opening the passage between the output port and the exhaust port, and the compressed air in the actuator and output line is emptied through the air holding port. The valve is used in the pneumatic control system of oil drilling rigs and geological exploration rigs for long-distance control and near-distance air inlet and outlet. The valve can also be used in the pneumatic system of other devices.
