Cast Iron Pressure Control Valve | SV1 SV2 SV5 SV11 | SBV1 SBV11 SV1E | Sequence & Unloading Valve

SV & SBV Series Cast Iron Pressure Control Valves

Product Overview: The SV and SBV series are versatile core components for pressure management in industrial hydraulic systems. Constructed with high-strength Cast Iron Bodies, these valves offer exceptional wear resistance and fatigue strength, maintaining structural integrity under high-pressure conditions. By reconfiguring internal pilot lines and spring settings, this series can function as Sequence Valves, Unloading Valves, or Low-Pressure Relief Valves. From the compact SV1/SV2 to the high-capacity SV11/SV12 specifications, they provide precise pressure setting and stable shifting characteristics.

Featured models: SV1, SV2, SV3, SV4, SV5, SV7, SV9, SV11, SV12, SV13, SV14, SV15, SV17, SBV1, SBV11, SBV12, SV1E, and SV2E.

Key Technical Advantages:

• Multifunctional Control Logic: Supports internal/external pilot and internal/external drain combinations for sequential motions, system unloading, or remote pressure control.

• High-Strength Cast Iron Material: Precision-cast valve bodies suppress vibrations caused by hydraulic pulses, significantly reducing operational noise.

• Wide Pressure Adjustment Range: Equipped with various high-linearity springs to ensure sensitive regulation without pressure drift across all pressure levels.

• Low Pressure Drop Design: Hydrodynamically optimized internal galleries ensure minimal energy loss even during high-flow operations.

• Flexible Mounting Options: Available in Subplate Mounting or Threaded Connections for seamless system integration.
