ASCO JOUCOMATIC 521 Series Pneumatic Valve Body

Description

This is a 52100078 solenoid valve body from ASCO JOUCOMATIC, a high-quality component for building reliable pneumatic control circuits. As a 5/2-way, double solenoid (bistable) valve, it provides precise control over pneumatic actuators like cylinders. The valve shifts position with an electrical pulse and holds its state until an opposing pulse is received, making it energy-efficient for applications where the state is held for long periods. This item is the valve body only; solenoid coils must be purchased separately to complete the assembly.

FAQ

This valve body is designed for ASCO's standard range of solenoid operators (coils). You need to select a coil with the correct voltage (e.g., 24V DC, 110V AC, 230V AC) and form factor that matches the stem on the valve body. Always consult the ASCO 521 series datasheet to ensure compatibility.

This is a bistable (double solenoid) valve body. It has provisions for solenoid operators on both ends. A pulse of electricity to one solenoid shifts the spool, and it will remain in that position until a pulse is sent to the opposite solenoid. It does not have a spring return.

The ASCO 521 series valves typically have a maximum operating pressure of 10 bar (1 MPa). The flow rate (Kv) for the G1/4 inch version is approximately 0.75 m3/h or 750 l/min. Please verify these values in the official product datasheet for your specific application requirements.
