Product Description
SL6 & SL10 Series Pilot Operated Check Valves (Subplate Mounted)
Product Overview: The SL Series Pilot Operated Check Valve is a cornerstone for ensuring precise positioning and fail-safe locking in high-performance hydraulic systems. Designed for subplate mounting, these valves allow free flow in one direction and controlled reverse flow only when a pressure signal is applied to the pilot port.
This category features premium configurations from the Yuken-type SL-G01 and Rexroth-type SL10 series, including the decompression-capable SL10-PB3-4X/SO311 and the versatile SL-G01-C6-R-D2-31. They are the premier choice for pressure-holding circuits in injection molding machines, CNC machine tools, hydraulic presses, and heavy-duty lifting equipment.
Key Technical Advantages:
Advanced Decompression Feature: The SL10-PB structure incorporates a decompression poppet to relieve system pressure before opening the main spool, minimizing hydraulic shock.
Zero-Leakage Integrity: Hardened precision seats guarantee zero internal leakage during long-term pressure holding, effectively preventing actuator drift.
High-Pressure Durability: Rated for operating pressures up to 31.5 MPa, capable of withstanding demanding industrial duty cycles.
Universal Compatibility: Complies with ISO 4401 mounting standards, ensuring direct interchangeability with major international brands for simplified maintenance.
