Norgren 8303703.9151.23050 Solenoid Valve - IP65
Part Number: 8303703.9151.23050
Quick Summary
Norgren 8303703.9151.23050 solenoid valve provides DN50 flow control for industrial piping. Operators often struggle with leaks, downtime, and compatibility gaps between actuation methods and established piping standards. Its IP65 protection ensures reliable performance in dusty and wash-down environments, while a -10 to 50 °C temperature range and 0.1 to 16 bar operating window support broad process needs. The cast steel body with a FPM seat seal delivers durability and predictable actuation, reducing maintenance intervals. For engineers, this means easier integration into existing valves & flow control systems and improved overall automation reliability in harsh plant environments.

Feature: Cast steel body offers high mechanical strength and chassis rigidity for long-term reliability in harsh environments. Business Impact: This minimizes deformation risks, reduces maintenance cycles, and lowers total cost of ownership. Application: Ideal for DN50 line control in heavy industry where vibration and exposure are common. Feature: Indirectly actuated solenoid with 2/2 normally closed operation ensures tight shut-off and energy-efficient control. Business Impact: Improves sealing integrity, reduces energy consumption, and shortens actuation times. Application: Suitable for pilot-operated control in pneumatic systems across manufacturing lines. Feature: Port Size DN50 and nominal 50 mm diameter standardize interfaces. Business Impact: Reduces integration effort with manifolds and piping, lowering installation time and risk of leaks. Application: Fits common industrial fluid circuits and retrofit projects. Feature: IP65 ingress protection enables operation in wash-down and dusty environments. Business Impact: Enables reliable performance in harsh production areas, minimizing unplanned downtime. Application: Ideal for food and beverage, chemical, and general process automation in challenging environments. Feature: Operating temperature -10 to 50 °C and operating pressure 0.1 to 16 bar provide broad process compatibility. Business Impact: Supports diverse applications without multiple part numbers, cutting inventory complexity. Application: Applies to pneumatic and light hydraulic circuits in process automation. Feature: FPM seat seal enhances chemical compatibility and seat life. Business Impact: Extends service intervals and reduces replacement costs. Application: Useful in environments with oils, coolants, and many solvents in standard industrial lines.

FAQs
To install, ensure you have a DN50 flange-compatible manifold and follow the Norgren installation guide EN1377005MO. Mount using recommended torque on flange bolts, align port orientation, and seal with the appropriate gasket. Connect the coil wiring per the specified voltage and verify the IP65 enclosure remains sealed before commissioning. Refer to the Datasheet for torque values and wiring diagrams.
The valve operates from 0.1 to 16 bar and from -10 to 50 °C. Staying within these limits ensures reliable 2/2 normally closed actuation and consistent seating with the FPM seal. Exceeding the range may impact response time, sealing performance, or longevity, so select alternatives rated for higher pressures or extreme temperatures if your process requires it.
Yes. The IP65 ingress protection rating means the valve is protected against dust ingress and water spray, making it appropriate for wash-down and dusty industrial environments. Ensure connectors and maintenance practices preserve enclosure integrity, and use compatible cleaning routines to avoid compromising seals or electrical connections.
This valve carries IP65 protection as documented in the product data. Its cast steel body and FPM seat seal are chosen for durability and chemical compatibility in standard industrial settings. While CE labeling specifics aren’t listed here, the IP65 rating provides a clear indication of suitability for protected environments in general industrial automation projects.
Use the official Installation Guide to pre-wire the coil, prepare a spare stem seal kit, and confirm flange torque values before operation. Keep a small inventory of DN50 gaskets and seals, and schedule preventive maintenance based on cycle counts. Properly sealed enclosures and correct wiring reduce field failures and extend valve life, lowering overall maintenance costs.
