The OP22 pneumatically actuated hydraulic directional control valve is the benchmark for efficiency and reliability in the tipping truck industry. Unlike other products, the patent-protected design of the OP22 was specifically created for tipping applications.
Our engineers redesigned its high-performance differential area direct-acting relief valve, which now provides minimal pressure drop and incredible stability and has a feature that makes it impossible to inadvertently over-pressurise the system past 3,200 psi.
160 l/min nominal twin spool tipper truck valve
220 bar maximum pressure
Proportional operation
Optional HydraForce port relief valves
1″BSPP service ports & 1 ¼” BSPP tank port
Handle option available
Cast & manufactured in Australia
Custom-designed large internal tank galleries for low-pressure
The OP55 is a larger derivative of the OP22. Our engineers designed the galleries inside the valve casting to provide minimal pressure drop, especially in the return to tank line, which allows the most efficient hoist down times in the industry.
250 l/min nominal flow capacity
245 bar maximum working pressure
Proportional operation
1-1/4” BSPP service ports & 1-1/2” BSPP tank port
Cast & manufactured in Australia
Custom-designed large internal galleries for low-pressure drop
Designed specifically for efficient, fast cycle times on truck and trailer
¼” BSPP Test Port option for accurate PRV setting (TP)
Oilpath Electric Hoist Blocking Valves utilise HydraForce normally closed poppet valves in conjunction with an aluminium body manufactured in-house and a manual override system from the pneumatic hoist block valve. This valve utilises the world-class HydraForce hardened steel poppet system and high-quality solenoid combination, providing fast, reliable operation and low leakage.
Maximum working pressure: 210 bar (3000 psi)
Sizes: 57 lpm ½” BSPP & 115 lpm 3/4”
Voltage: 12 or 24-volt Deutsch Coils
In-line, direct-acting, solenoid-operated hoist check valve for use in block or load-holding
To raise pressure flows from port 1 to port 2
To lower flow goes from port 2 to port 1
Hardened seats for long life, low leakage, and low-pressure drop
The Oilpath OP-APV-16-22 is the third generation of this market-leading hoist-blocking product. The latest revision provides an even lower pressure drop through the body, utilising patented technology. The design also incorporates a large ratio “balanced” pneumatic cylinder, which uses extremely low (2.1 bar) air pressure to activate the system.
Maximum operating pressure: 207 bar (3,000 psi)
Flow: 150 l/min nominal
Leakage: 0.15 cc/min (3 drops/min)
Air Pressure: 80 psi ¼” BSPP connection
Service Ports: 1″ BSPP
In-line, direct-acting, pneumatically operated hoist check valve for use in block or load-holding
To raise pressure flows from port 1 to port 2
To lower flow goes from port 2 to port 1
Hardened seats for long life, low leakage and low-pressure drop.
