Overview
The Parker K142231 is a 1/2 inch pneumatic sub-base manifold engineered for direct compatibility with Parker Schrader Bellows L665 and L675 series solenoid and pilot-operated directional control valves. This manifold base provides a robust mounting platform for stacked valve configurations, commonly deployed in Ready Mix concrete batch plant control systems and medium-duty industrial automation.
Key Features
- 1/2 inch NPT ported sub-base design for valve stacking and compact valve banks
- Direct fit for L665 and L675 series Schrader Bellows directional control valves
- Aluminum alloy construction for corrosion resistance and lightweight mounting
- Integrated pilot supply and exhaust passages for solenoid and air-pilot valve operation
- Reduces tubing length and improves pneumatic response time vs. inline configurations
- Field-proven in batch plant and material handling applications
