The OILPATH OP 221: The Benchmark in Hydraulic Hoist Lift and Drop Control for Your Bogie, Tandem and Semi Tipper Truck. Made in Australia!
Upgrade your tipping efficiency and support Australian manufacturing with the industry-leading OILPATH OP 221, the leading 3 Port, Single Spool, Hydraulic Hoist Control Tipper Valve!
Unlike generic valves, the OILPATH OP 221 is specifically designed for the telescopic lift hoists found on Bogie, Tandem and Semi Tipper Truck applications.
Featuring patented technology to maximise oil flow and performance, and proudly manufactured right here in Australia.
The Secret's in the Design:
Engineered Flow Paths:
OILPATH engineers designed the internal passages to minimise pressure drop, especially during lowering (Hoist / Tipper Down). This means faster and more efficient tipping cycles. As with every valve in the OP Range, the spool bore in the OP 221 is hand-honed to individually match its hardened steel spool, producing extremely tight, consistent tolerances. That precision fitment is what keeps internal leakage low and pressure control sharp, cycle after cycle, year after year.
Smart Pressure Relief Valve:
The high-performance HYDRAFORCE relief valve offers minimal pressure drop and exceptional stability, preventing accidental over-pressurisation beyond a safe 3,200 psi.
Please Note: Relief Valve is factory set and locked to 172 bar (2,500 psi)
Built to Last:
- Heavy-Duty Construction: The valve body is crafted from high-tensile strength cast iron for unmatched durability.
- Premium Materials: Hardened steel spool and Buna-N (Nitrile) seals ensure smooth operation and long service life.
- Hand-Honed Bore Fitment: Each bore is individually honed to match its hardened steel spool, giving extremely fine tolerances and very low leakage rates — a key reason OP Range valves are known to run reliably for 20 to 30 years.
Additional Features:
- High Flow Capacity: Handles up to 160 litres per minute (Lt/min) for efficient tipping.
- Maximum Pressure: Withstands working pressures up to 220 bar (3,200 psi).
- Convenient Connection Ports: Utilises standard 1" BSPP for Oil Supply and Hoist Supply/Return port and a 1-1/4" BSPP Tank Return Port for easy installation. Test Ports are 1/4" BSPP. Compressed Air Connections for Pneumatic Actuators are 1/8" BSPT.
- Built-in Diagnostics: The 1/4" BSPP test ports allow for easy pressure checks and setting of auxiliary functions.
- Moisture-Resistant Design: The pneumatic actuator system includes a vacuum elimination feature to minimise moisture ingestion, extending valve lifespan.
- Spare Parts and Seal Kits: Always available and in stock.
Don't settle for generic solutions! The OILPATH OP221 is the clear choice for reliable, efficient, and safe tipping operations, while also supporting Australian innovation and manufacturing. Upgrade your Bogie, Tandem or Semi Tipper today and choose Australian-made quality!
Why the OP221 Costs More — and Lasts Longer
- Hand-honed bore individually matched to the hardened steel spool — not mass-tolerance manufacturing
- Purpose-engineered flow paths for minimal pressure drop on lowering, unlike generic hoist valves
- HYDRAFORCE relief valve, factory set and locked, for reliable, stable over-pressure protection
- Typical service life of 20–30 years before replacement is needed
- Spare parts and seal kits always in stock, for the life of the valve
