Norgren 8303700.9150.00000 Cast Steel DN50 Valve 2/2 NC
Part Number: 8303700.9150.00000
Quick Summary
Norgren 8303700.9150.00000 cast steel valve provides solenoid-free, normally closed control for DN50 piping. In many processes, coil-powered valves introduce EMI, wear, and higher energy use; this model minimizes that risk while delivering reliable shut-off. While the datasheet lists operating range and materials, certifications such as CE conformity, SIL suitability, and IP-rated protection should be confirmed on the official datasheet and in your system requirements. Its DN50 flange compatibility, cast steel body, NBR seals, and 0.1–16 bar range support efficient integration with standard pneumatic loops, delivering durable, low-maintenance performance for industrial automation opportunities. This translates to reduced downtime, easier installation, and lower total cost of ownership in manufacturing environments.

Solenoid-free, normally closed operation eliminates coil wear and electromagnetic interference, delivering a maintenance-light control path. The business impact is lower energy use and fewer failure points, translating into higher line availability for packaging, bottling, and process automation. Cast steel body provides high mechanical strength and durability in demanding industrial environments. This construction reduces replacement frequency and total cost of ownership, supporting long service life in air preparation, plant automation, and high-cycle pneumatic circuits. DN50 port size with flange connections enables straightforward integration with standard piping and existing manifolds. This reduces installation time and eliminates the need for adapters, making it ideal for retrofit projects and new lines in manufacturing and packaging plants. Materials - Body: cast steel; Materials - Seat Seal: NBR. The combination ensures robust sealing under 0.1–16 bar and -10 to 50 °C conditions. It supports predictable performance and simpler maintenance in everyday industrial use. Operating range of -10 to 50 °C and 0.1 to 16 bar covers typical factory air systems, enabling broad applicability. The 2/2 NC operation and DN50 size align with standard automation circuits, helping engineers design efficient, cost-effective solutions while meeting safety and reliability targets. Range 83030 and the IMI Buschjost branding help with compatibility in spare parts and stock management; The valve is designed to slot into existing Norgren and IMI Buschjost lineups, streamlining procurement.

FAQs
Install the valve using standard DN50 flange hardware and tighten to the manufacturer’s flange torque specification. Ensure correct orientation for a 2/2 NC circuit and connect the supply air to the appropriate port. Refer to the Installation Guide (PDF) for step-by-step guidance and best practices to avoid leaks and ensure reliable operation.
The valve operates from -10 to 50 °C and supports 0.1 to 16 bar (1.45 to 232 psi) inlet pressure. It uses a DN50 port size with a cast steel body and an NBR seat seal, suitable for standard pneumatic lines in general industrial environments. Always validate your specific media compatibility per your system requirements.
Yes, the solenoid-free 2/2 NC design is well-suited to dry, clean compressed air and many inert gas applications common in packaging and process automation. Its flange connection and DN50 bore support mid-to-high flow requirements. For solvent-containing or aggressive media, verify compatibility with the NBR seal and consider alternative elastomers if needed.
The provided data does not specify explicit certifications. CE conformity, SIL suitability, and IP ratings are common for this class, but must be confirmed on the official datasheet. Download the Datasheet (PDF) and Installation Guide (PDF) from the links to verify applicable certifications for your region and safety requirements.
Solenoid-free operation eliminates coil wear and reduces electrical infrastructure, lowering maintenance costs and the risk of electrical faults. The robust cast steel body and NBR seals offer durable service in typical factory conditions, contributing to higher uptime and lower total cost of ownership over the asset life. Expect simplified spares management with range 83030 integration.
