| Part Number | 702-21-09230 |
| Type | Hydraulic Control Valve (Pilot-Operated Directional Valve Pressure Relief Valve) |
| Function | - Controls hydraulic fluid flow direction/pressure in the circuit - May act as a proportional or on-off valve for actuators (e.g., cylinders, motors) |
| Hydraulic Parameters | - Max Working Pressure: 350 bar (5076 PSI) - Rated Flow: 80 L/min (21.1 GPM) - Operating Pressure Range: 5-350 bar (72.5-5076 PSI) - Response Time: ≤50 ms (from neutral to full stroke) |
| Port Connections | - Inlet/Outlet Ports: SAE 3/8"-18 ORB (O-Ring Boss) or M22×1.5 metric threads - Pilot Port: 1/8" NPT (for remote control signal) - Number of Ports: 4-way (P, T, A, B) for directional control |
| Control Type | - Actuation: Pilot pressure (hydraulic) or manual override - Spool Position: 3-position (neutral, forward, reverse) with spring-centered return |
| Material | - Body: Cast iron (GGG40) or aluminum alloy (ADC6) - Spool: Chrome-plated steel (hardness ≥HRC 55) - Seals: FKM (Vito-n, -20°C to +150°C) for high-temperature resistance |
| Mounting | - Style: Subplate mount (ISO 4401 standard) or flange mount - Bolt Pattern: 4-bolt M8×1.25 (100mm × 80mm spacing) |
| Filtration Requirement | - Recommended Filter Rating: ≤25 μm (ISO 4406: 18/16/13) to prevent spool wear |
| Design Features | - Low-pressure drop (≤1.5 bar at rated flow) for energy efficiency - Built-in damping for smooth operation and reduced pressure spikes - Neutral position leakage: ≤50 mL/min (at max pressure) |
| Weight | 3.5 kg (7.7 lb) (cast iron body) / 2.0 kg (4.4 lb) (aluminum body) |
| Standards Compliance | - ISO 12261 (hydraulic fluid power components) - CE (Machinery Directive 2006/42/EC) |
