FAQs
Install with flanged DN50 mating ports, aligning bolt holes precisely to avoid flange distortion. Use appropriate gaskets and torque per standard DIN/ISO flange specs to ensure a leak-free seal. Verify that the valve orientation and access for inspection are suitable for maintenance routines and inline accessibility.
Key specs include a 50 mm nominal diameter (DN50), 2/2 normally closed function, flanged body in cast steel, and FPM seat seals. Operating temperature is −10 to 50 °C with an operating pressure range of 0.1 to 10 bar. Port size is DN50, and the valve operates without an integrated solenoid.
Yes. The DN50, 2/2 NC configuration with a robust cast steel body suits many packaging and process control applications. Its solenoid-free design simplifies control wiring, while the 0.1–10 bar range supports common pneumatic systems. For high-cycle applications, confirm the specific duty cycle in the datasheet and ensure alignment with your control philosophy.
Verify CE compliance for your region, IP ratings for enclosure protection, and SIL compatibility if the valve participates in safety-related functions. The data sheet for 8303703.9100.00000 should list the exact certifications; if not visible here, consult the datasheet or contact the supplier to confirm current certifications before integration.
The absence of a solenoid reduces electrical components and potential failure points, lowering maintenance needs and energy use. The cast steel body and FPM seals deliver durability in challenging environments, contributing to longer service life and reduced replacement costs. Regular inspection of seals, flange integrity, and mounting fasteners supports steady performance and predictable ROI.
