Hand Lever Valve Model 4HV21008, directed at air applications, with directacting action and manual lever override. This 4port, 2position valve is designed for reliable, immediate control in compact pneumatic circuits. Key specifications Product Name: Hand Lever Valve Model: 4HV21008 Fluid: Air Action: Direct Acting Type Actuation Type: 4 Ports, 2 Positions Working Pressure: 1 to 10 Kgf/cm2 Operating Angle: 90 degrees Port Diameter: 11.5 mm (0.453 inches) Mount Size: 49 x 49 mm (1.9' x 1.9') Valve Size: 62 x 62 x 72 mm (2.4' x 2.4' x 2.8') Lever Size: 85 x 19 mm (3.3' x 0.75') Material: Plastic, Metal Key benefits Directacting design provides fast, positive response without requiring pilot signals. Manual hand lever offers immediate override and control, useful for setup, testing, and safety interlocks. Compact form factor fits into tight spaces while maintaining robust performance. Suitable for standard air systems with a 4port, 2position configuration, enabling simple routing and actuation. Broad operating pressure range (1–10 Kgf/cm2) supports a variety of pneumatic applications. Durable construction using plastic and metal combines lightweight handling with reliable longevity. Typical applications Manual control of a pneumatic cylinder in small automation cells or assembly lines. Quick shutoff or air routing in test rigs or prototyping setups where space is limited. Auxiliary or safety valve in compact pneumatic manifolds for equipment with restricted mounting area. Notes Designed specifically for air systems and 4port, 2position configurations. Leverbased actuation provides a straightforward, nonelectrical control method ideal for maintenance, diagnostics, and manual operation.
