Detail
1. Characteristic:
23QA-15 two-position three-way pneumatic control valve is a new type of pneumatic control reversing valve, which is an improved alternative to the original QF506 dual-purpose relay valve.
The valve has one air source port (P) one output port (A), one exhaust port (O) and one control port (K). It can be used as a normally disconnected or normally open type, depending on actual needs.
When used as a normally broken type, connections are made according to the air port symbol.
When used as a normally open type, only the push gas port O is changed to the gas source port; when used as a normally disconnected type, the piston in the valve moves forward under the action of the control gas, and the upper spool seals with the valve seat, cutting off the passage between the output port and the gas connection port, and the gas source port is connected to the output port.
In the absence of control gas, the output port is connected to the exhaust port, and the compressed air in the actuator and output piping is evacuated through the exhaust port.
When used as a constant-pass type, in the absence of control air input, the output port is connected to the air connection port, and compressed air is delivered directly to the actuator through the channel in the valve.
23QA-L15 two-position three-way pneumatic control valve is mainly composed of valve body, stem, spool, piston, spring, seal and other components.
The valve has the advantages of smooth operation, simple installation, small leakage, large circulation area, etc.
