Hydraulic Elevator Flow Control Valve
Budget: ₹12,500 – ₹37,500 INR
I’m developing a new elevator valve that relies on a single acting plunger cylinder and I need a purpose-built hydraulic flow-control valve to manage it. The valve has to be solenoid-operated (simple On/Off actuation is fine), handle 100 LPM, and work smoothly anywhere between 10 bar and 60 bar.
Upward travel is powered by a constant-RPM motor; downward travel is purely gravity driven, so I must be able to start, accelerate, decelerate, and stop the car cleanly in both directions (to be controlled on the valve mechanically). During descent, speed has to remain constant regardless of load, which means reliable pressure-compensated flow control.
Core requirements
• Aluminium body and internals where possible for weight and cost efficiency.
• Integral direct-acting relief valve set to open above the chosen maximum but with a lock-out that prevents any operation below 5 bar.
• Ports, seals, and mounting pattern compatible with standard elevator power-unit layouts.
• No hydraulic shocks or chatter during transition phases.
What I’d like to receive
1. Detailed hydraulic schematic showing all ports and flow paths.
2. 3D CAD model (STEP or SolidWorks) plus fully dimensioned manufacturing drawings.
3. Sizing calculations for orifices, spool land geometry, spring rates, and relief-valve setting.
4. A brief validation—CFD or MathCAD, for example—demonstrating pressure compensation during descent and stable performance over the full 10–60 bar range.
5. Assembly, test, and commissioning procedure notes I can hand to the shop and field technicians.
If you’ve designed elevator or crane valves before, that’s a bonus, but anyone confident with hydraulic valve design, fluid simulation, and aluminium machining tolerances will have everything needed to deliver.
