Product Description
LIC Hydraulic’s PVAC Series pilot hydraulic control valves (including PVAC1, PVAC2, and PVACBL) are the “brain” of high-precision hydraulic maneuvering. Designed to reduce high system pressures into stable, manageable pilot signals, these valves are critical for the operation of excavators, cranes, and specialized mobile machinery. We offer 100% Drop-in Interchangeability for complex specifications like PVAC1PCMNS35 and PVAC2MCMNSJW35. Featuring hardened steel spools and precision-machined bores, every PVAC valve undergoes 100% pressure-stability testing to ensure a smooth, lag-free operator experience even in high-vibration mining and construction environments.
Technical Specifications (Bulleted List)
Series Framework: PVAC1, PVAC2 (Single or Integrated block), PVACBL (Standard Relief/Reduction).
Set Pressure: $2.0\text{ MPa}$ (20 bar) to $3.5\text{ MPa}$ (35 bar) standard options.
Max Inlet Pressure: $35\text{ MPa}$ ($5076\text{ PSI}$).
Flow Capacity: Optimized for pilot signaling, typically $5\text{–}15\text{ L/min}$.
Connectors: JW/JP series (Deutsch/Amphenol compatible) for electronic-control versions.
Fluid Compatibility: Standard mineral-based hydraulic oils (ISO VG32/46).
Key Technical Advantages
Precision Pressure Regulation: Integrated dampening elements filter out main pump pulsations, delivering a “rock-steady” pilot flow that eliminates joystick jitter and improves safety.
Low Hysteresis Performance: The micro-finished spool ensures minimal friction, providing an instantaneous response to operator input—essential for complex, multi-function coordinated movements.
Compact Integrated Manifold: PVAC2 units allow for the integration of filters, relief valves, and solenoids in a single block, reducing the hydraulic footprint and potential leak points.
Heavy-Duty Construction: Built from high-grade alloy steel, the internal components are resistant to abrasive wear, ensuring consistent pressure settings over thousands of operational hours.
Application Areas
Excavator Controls: Providing pilot oil for joysticks and travel pedals.
Mobile Cranes: Precise load-sensing pilot signal distribution for winches and booms.
Industrial Robotics: Pressure reduction for hydraulic grippers and actuators.
Expert Maintenance Tips
Verify Pilot Pressure: After installing a PVAC1PCMNS35, always verify the output with a calibrated gauge. Improper pilot pressure is the leading cause of “sluggish” machine response or failure to release hydraulic brakes.
Strict Filtration Standards: The internal orifices of pilot valves are extremely small ($<1\text{ mm}$). To prevent spool sticking, ensure your pilot filter ($10\text{ micron}$ absolute) is replaced at the recommended intervals.
O-Ring Integrity: During the installation of PVACBL units, ensure all mounting surfaces are pristine. Because pilot valves are often located near the operator cab, even a minor weep can result in significant messy buildup in sensitive areas.
