Sand-vik 55194637 Safety Proportional Valve
Part No. 55194637 is an original electro-hydraulic proportional relief valve for Sand-vik DD/DL series underground drill rigs. It realizes stepless proportional pressure regulation and overpressure protection for hydraulic systems. This cartridge valve comes in black finish.
1. Basic Information
- Part Number: 55194637 (Full code: 551 94637)
- Brand: Sand-vik
- Type: Proportional pressure relief valve with safety unloading function
- Applicable Models:
- DD Series: DD2100, DD2710, DD3110 and other underground development drill rigs
- DL Series: DL2100, DL2710 and other longhole drill rigs
- Matched equipment: Hydraulic circuits of RDX5 hydraulic rock drills
2. Core Functions
- Proportional pressure regulation: Receives 0–10V DC or 4–20mA electrical signals to adjust system pressure continuously and linearly.
- Safety relief: Releases pressure proportionally when overloaded, protecting hydraulic pumps, motors, rock drills and other precision components.
- Load sensing: Automatically adjusts pressure according to working load to save energy and reduce heat generation.
3. Key Specifications
- Working Pressure: 0–350 bar (Max regulating pressure: 350 bar)
- Flow Range: 2–80 L/min
- Input Signal: 0–10V DC or 4–20mA
- Coil Voltage: 24V DC (standard for drill rigs)
- Material: High-strength carbon steel valve body, hardened valve spool, FKM rubber seals
- Operating Temperature: -30℃ ~ +120℃
- Installation: Cartridge type, fits standard valve cavities
4. Appearance & Structure
- Cylindrical black cartridge valve body with a proportional solenoid mounted on the top.
- Integrated assembly consisting of valve spool, spring and proportional solenoid, equipped with O-ring seals.
- Original marking: Part number 55194637, Sand-vik logo, voltage and pressure parameters.
5. Replacement & Compatibility
- Genuine replacement: 55194637 (single standard model, no upgraded variants)
- Interchangeability: Not compatible with Epiroc 606001108 or other similar parts due to different brands, port sizes and control logic.
- Installation position: Main hydraulic valve block, for pressure control circuit of rock drills.
6. Common Faults & Maintenance
- No pressure output: Burnt coil, stuck valve spool or signal loss.
- Unstable pressure: Contaminated hydraulic oil, worn seals or faulty proportional amplifier.
- Maintenance cycle: Inspect every 500 working hours. Replace hydraulic oil, clean filter elements and regularly check coil insulation.
