Two-Way Pilot-Operated 12V Solenoid Valve 1/4" - Code 27567
The professional-grade 1/4" 2-way pilot-operated solenoid valve (Product Code: 27567) is a high-performance fluid-dynamic component engineered for the automation and section control of liquid lines on agricultural boom sprayers, mist-blowers, and industrial spraying arrays. Powered by a low-voltage 12V DC system for secure integration with vehicle electrical systems, this valve ensures rapid switching metrics, leak-proof shutting, and premium operational stability across demanding field environments.
Design Details and Hydro-Mechanical Architecture
This technical solenoid valve is configured with a "Normally Closed" (NC) circuit logic, restricting fluid flow when de-energized to serve as a reliable safety barrier against accidental chemical runoff or compound contamination. Utilizing an advanced pilot-operated (servo-assisted) diaphragm mechanism, the assembly harnesses the differential fluid pressure across the line to assist the main diaphragm stroke, enabling smooth modulation of fluid volumes up up to 4.5 liters per minute within a 0 to 8 bar operational pressure range. The mechanical infrastructure incorporates a specialized bayonet-style armature tube alongside an integrated rubber coil-retaining dampener, a pairing developed to streamline field replacement routines and isolate the coil assembly from severe machine-induced vibration loops. To withstand the aggressive chemical breakdown triggered by concentrated pesticides, liquid herbicides, and copper solutions, all internal components and reciprocating plungers are fully manufactured from heavy-duty Stainless Steel (INOX). Premium elastomeric sealing materials ensure an extended fluid temperature spectrum rating from -10 up up to +130°C, locking in operational reliability regardless of seasonal weather extremes or high-temperature fluid loops.

Installation Guidelines and Fleet Rig Setup Advice
- Hydraulic Flow Path Alignment: Strictly follow the designated stream direction during pipeline assembly. Connect the primary supply line manifold to Port 1 (INLET) and link the secondary output hose feeding the boom jets to Port 2 (OUTLET).
- Coil Fitment and Vibration Dampening: Leverage the quick-lock bayonet design to mount the 12V drive coil over the armature core. Verify that the rubber coil-retaining dampener is properly seated to absorb mechanical impact shocks stemming from rough terrain or vehicle engines, preventing core stress fractures.
- Pre-Assembly Flushing Protocol: Thoroughly rinse the fluid conduits to clear away chemical crystals or installation debris before locking the valve into the grid, preventing sediment entrapment on the pilot seat. Flush with clean water at the close of every treatment block to preserve the internal Stainless Steel assemblies during storage blocks.
