NOV-SCHAFFER DTL ENGR 1710-4100 Solenoid Valve

NOV-SCHAFFER DTL ENGR 1710-4100 SOLENOID VALVE

The NOV-SCHAFFER DTL ENGR 1710-4100 Solenoid Valve is a premium, heavy-duty fluid control valve for high-pressure maritime automation and oilfield drilling systems. Designed by DTL Engineering Fluid Technologies, a member of the renowned NOV-Schaffer group, this solenoid valve is engineered to withstand the harshest environments on earth, from offshore drilling rigs to the engine rooms of deep-sea commercial vessels.

This valve offers quick ultra-reliable directional fluid control with a maximum permissible working pressure (MAWP) to 3000 PSI. Its corrosion-resistant metallurgy and military-spec electrical coil encapsulation protect it against salt spray, excessive humidity, thermal shock and the continual structural vibrations unique to maritime machinery areas. 1710-4100: When marine pressure cycling exceeds the capability of ordinary industrial valves, the 1710-4100 provides process continuity and failsafe system functioning.

Technical Specifications

Features: ENGR 1710-4100 Solenoid Valve

1. Heavy Duty Substructure 3000 PSI Pressure: Specifically designed for high pressure maritime hydraulic and offshore oilfield blow-out preventer (BOP) control circuits without structural degradation.
2. Marine-Grade Corrosion Resistance: Protected by specific metals designed to endure extreme exposure to marine environments, untreated sea air and abrasive drilling fluids.
3. Rapid reaction Electromagnetic Coils: These coils are designed for immediate actuation and use precision wound internal solenoids to provide rapid reaction times for critical fail safe and emergency shutoff situations.
4. Zero Leakage Internal Sealing: Utilises high durometer internal elastomeric seats for premium sealing thresholds during strenuous cyclic stresses.
5. Superior Anti-Vibration Resistance: Solid block construction may absorb mechanical resonance frequencies from neighbouring mud pumps, ship main engines and large auxiliary machinery. It weighs a substantial 9.1 Kg.

Engineer’s Inspection Insight:

When unboxing or preparing the 1710-4100 Solenoid Valve for replacement during an active drydock or maintenance window, always inspect the machined connection faces for scoring. Because this valve weighs 9.1 Kg, it is crucial to use proper mechanical lifting assistance or a rigging strap if installing it inside dense overhead valve nests. Attempting to support a block valve of this weight manually while tightening mounting bolts can lead to cross-threading or uneven seat compression.

Optimal Performance Guide:

1. Hydraulic Fluid Hygiene: The close-tolerance pilot internals of high-pressure valves like the 1710-4100 are sensitive to micro-particulate contamination. Ensure your hydraulic oil is filtered to at least ISO 4406 16/14/11 cleanroom standards before commissioning the circuit.
2. Prevent Coil Burnout: Over-voltage or voltage ripples inside unstable shipboard 24VDC/110VAC auxiliary buses can cook the electromagnetic coil. Always verify that your supply voltage matches the coil stamping exactly (±5%) and inspect the earth ground to prevent internal galvanic corrosion.
3. Solenoid Cycle Auditing: If the valve sits idle inside an emergency backup loop (such as a standby hydraulic circuit), program a weekly or bi-weekly manual stroke test. Static fluids in marine environments can cause seal stiction, which degrades response times when a sudden system emergency strikes.
