Overview
The Parker L6653921153 Valvair II Series is a heavy-duty, all-metal valve that will shift when called upon, even after being idle for an extended period of time. This 4-way 3-position double solenoid manifold-mounted directional control valve uses line pressure to shift the spool, providing dependable fluid flow control in hydraulic and pneumatic circuits.
Key Features
- Synthetic rubber o-ring seals specially compounded for superior wear and abrasion resistance
- Solenoids encapsulated in epoxy for low power consumption and maximum life
- Double solenoid operator for synchronized flow control
- Double solenoid valves mounted horizontally for optimal performance
- All ports blocked (APB) function in neutral position
- Plug-in connection for simple installation and maintenance

Typical Applications
This solenoid air control valve functions as a switch to control air flow in automotive, manufacturing and power transmission applications. Common uses include cylinder actuation, gate and butterfly valve control, and automated fluid circuit switching. The valve minimises energy consumption by allowing only the required amount of air to flow through a system, and aids in maintenance of consistent and stable operations, ensuring machinery runs smoothly without abrupt fluctuations.
