Hydraulic valves
for every
circuit function.
Directional, pressure, flow control and check valves from Parker, Vickers, Eaton and Danfoss — supplied with the application engineering knowledge that comes from designing and building complete hydraulic systems ourselves.
The right valve
for every
hydraulic function.
Hydraulic valves govern every function in a fluid power circuit — direction, pressure, flow and check. Selecting the wrong valve, or specifying to a generic catalogue rather than the actual system requirements, is the most common root cause of hydraulic system reliability failures we see in the field.
Because Fluidline designs and builds complete hydraulic systems — power packs, cylinders, unloaders, cranes — we source and supply valves with genuine application knowledge. We know which Parker proportional valve suits a load-sensing circuit, which Eaton directional valve handles the cycle frequency in a sugar mill drive, and which Vickers pressure relief setting protects a crane hoist. That knowledge is what we bring to every valve enquiry.
We supply directional control valves, pressure control valves, flow control valves and check valves from Parker, Eaton (formerly Vickers), Danfoss and Vickers-branded legacy stock. We also supply complete pre-assembled manifold blocks to customer schematics, machined and tested in our Kundli facility.

Four valve families
for complete
circuit coverage.
Directional Control Valves
4/3 and 4/2 spring-centred and detented spool valves for controlling actuator direction and hold. Available in solenoid, pilot and manual actuation in NG6, NG10 and NG16 bodies.
Pressure Control Valves
Direct-acting and pilot-operated pressure relief valves, pressure reducing valves, sequence valves and counterbalance valves. Critical for system protection and load-holding in crane and cylinder circuits.
Flow Control Valves
Throttle valves, pressure-compensated flow controls and proportional flow valves for speed regulation. Available in fixed and adjustable configurations, meter-in and meter-out arrangements.
Check & Pilot-Operated Check
Standard check valves for backflow prevention and pilot-operated check valves (POCVs) for load holding in vertical cylinder and crane hoist circuits. Available in inline and cartridge format.

systems we serve.
More than a
distributor.
Application Engineering
We have designed and built complete hydraulic systems for 25 years. When you ask us to specify a valve, we are drawing on real system-level knowledge, not just a product catalogue.
Stock & Fast Dispatch
Standard directional, pressure and flow control valves in common sizes are held in stock at our Kundli facility. Most stock orders ship within 2–5 working days.
Manifold Assembly
We design, machine and assemble complete manifold blocks to your hydraulic schematic, with all valves pre-fitted and leak-tested before dispatch. Reduces site commissioning time significantly.
