SOLENOID OPERATED DIRECTIONAL VALVE

SWH-G03 SHOCKLESS TYPE
FEATURES

• Indicating lights and bolt kits are standard.
• Coil screws are especially designed to prevent shocks.
• Electrical connections are joint box type or Hirschman DIN type plug-in connector.
• Joint box is waterproof and dust-resistance.
• The space for electrical connections is large enough for connection layout.
• Electrical connection points are aligned with the axial direction to be compatible with modular system.
• The valve mounting screws are on the outside of the body for ease of installation and repair.
• High pressure up to 310 BAR (4500 PSI), large flow rates up to 80 LPM (21 GPM).
• The ideal design of flow passages to minimize pressure drop.
• High back pressure up to 160 BAR (2350 PSI)
• Manufactured with specifications that allows for parts and accessories interchangeability.
• Specifically designed to control the shock or "bang" in hydraulic systems.
• Minimizes the effect of pressure peaks or instantaneous high flow rates common in many hydraulic systems.
