SOLENOID OPERATED DIRECTIONAL VALVE

SWH-G03 SERIES

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.
• 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), allows for large flow rates up to 120 LPM (32 GPM).
• 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.

ELECTRICAL SURGE CONTROL MODEL SWH - G03 - *** - D ** - ** - LS

FEATURES
• Suppresses the surge voltage.
• Eliminates sparks between relay contacts.
• Extends the life of the relay contact.

EFFECTS

• Improves the reliability of the control relay.
• Extends the life of conventional relays.
• Can be operated with a miniature relay.
• The RAC rectifier built-in DC model eliminates sparks at the control relay contact. It can be directly operated with a PLC (programmable logic controller).
