The VU-8303-686-5-13 model from Schneider Electric is engineered as a versatile 3-way globe valve assembly. Constructed with a durable cast iron body, this unit measures 3 inches in size, ideal for handling substantial flow in multiple applications.

This valve boasts impressive Cv ratings, measuring 110 for mixing and 120 for diverting fluid paths. It utilizes a brass trim material, further enhancing its efficiency. The actuator is designed to deliver a robust force of 337 lbf (1500 N), ensuring reliable performance in diverse environmental conditions.

Operability is facilitated via a non-spring return (NSR) mechanism, providing fail-safe capabilities under various circumstances. The valve responds to floating or proportional control signals, accommodating input options of 0-10 Volts DC, 2-10 Volts DC, or the range of 4-20 mA. Real-time feedback is available through a 2-10 VDC output.

This assembly operates effectively within a supply voltage range of 24 VAC or 20-30 VDC, making it suitable for numerous electrical installations. The enclosure maintains a NEMA 2 rating, supporting vertical mounting with conduits in place.

A humidity tolerance of 5 to 95% RH without condensation ensures functionality in varying conditions. The valve is capable of operation within temperatures from -10°C to a maximum of 45°C (limited to a fluid temperature of 138°C). The connection type adheres to ANSI Class 125 Flanged standards, promoting straightforward installation and integration into existing systems.
