THM – CV08 – Direct Acting Ball Type Cartridge (Check Valve)
Achieve absolute load-holding security and impenetrable reverse-flow protection with the THM CV08 Series Direct Acting Cartridge Check Valve. Engineered for precision and rugged reliability, this compact, ball-type logic element instantly blocks reverse fluid flow to protect sensitive downstream components and lock hydraulic cylinders in place. Capable of sustaining cartridge pressures up to 315 bar and delivering a rated flow of 30 L/min, the CV08 guarantees near-zero internal leakage (≤0.3 ml/min). Built to endure extreme outdoor environments with a massive temperature operating range, it is the ultimate compact safety valve for the heavy civil, road, and earthmoving equipment that builds our world.
Core Technical Specifications:-
- Valve Architecture: Direct Acting Ball Type Cartridge (Check Valve)
- Model Cavity Size: 08
- Maximum Operating Pressure: 315 bar (Cartridge) | 207 bar (Anodized Aluminum Body)
- Rated Flow Capacity: 30 L/min
- Internal Leakage: ≤0.3 ml/min (Maximum at 250 bar)
- Operating Temperature Range: -35°C to +120°C
- Fluid Compatibility: Mineral-based fluids (Consult factory for other media)
Key Features & Engineering Advantages:-
- Near-Zero Leakage Sealing: The high-precision, direct-acting ball mechanism creates an incredibly tight seal against the valve seat, allowing an absolute maximum of only 0.3 ml of bypass per minute at 250 bar. This ensures rock-solid load holding without cylinder drift.
- Extreme Temperature Resilience: Rated to perform flawlessly in punishing conditions ranging from freezing -35°C winters to blistering +120°C operational heat, ensuring your machinery never stops working, regardless of the climate.
- Durable Manifold Integration: The cartridge itself handles extreme 315-bar spikes, while the standard valve body is machined from premium Anodized 6061T6 aluminum alloy (safely rated for continuous 207-bar operations), providing an excellent strength-to-weight ratio for mobile manifolds.
- Compact Cavity Design: The industry-standard 08-size footprint allows engineers to design incredibly dense, space-saving hydraulic blocks for compact machinery where every millimeter counts.
- Optimized Fluid Cleanliness: Engineered for longevity when paired with proper system maintenance. Recommended filtration levels are strictly defined (ISO17/15/13 for critical applications; ISO20/18/14 for non-critical), ensuring the precision ball seat remains pristine over thousands of cycles.
Ideal Industry Applications:-
The tight load-holding, wide temperature range, and compact footprint of the CV08 Series make it a critical safety and flow-control component for:
- Heavy Civil & Road Machinery: Serving as an essential load-holding and anti-cavitation valve in the compact manifolds of asphalt pavers, road rollers, and motor graders operating in extreme weather conditions.
- Mobile Earthmoving Equipment: Securing auxiliary attachments and preventing reverse flow in the pilot circuits of mini-excavators, wheel loaders, and compact track loaders.
- Mobile Material Handling: Providing leak-free load locking for the hydraulic suspension and lifting cylinders on industrial forklifts, scissor lifts, and mobile cranes.
- Industrial Power Units: Acting as a space-saving pump isolation check valve in the centralized HPUs of manufacturing presses.
