II. Structural Features & Operating Principle

• Configuration:​ Three-port solenoid valve, pilot-operated via an external air source. The solenoid drives the pilot valve, which in turn controls the main spool.
• Seal Material:​ Seat seals use NBR or similar rubber, suitable for water, coolant, etc.
• Stem Bushing:​ Material has hardness and strength not exceeding the stem’s, and does not form galvanic corrosion with the stem or body when immersed in water.
• Water Hammer Suppression:​ Design reduces water hammer by approximately 20%, suitable for frequently cycled coolant lines.
• Modular Design:​ Can be banked with SJ2000/SJ3000 series valve manifolds. Up to 16 double solenoid valve stations or 32 single solenoid valve stations can be connected via a 34-pin connector, facilitating easy station addition/removal and valve replacement.

III. Typical Applications

• Machine Tool Coolant Control:​ On/Off control of coolant for lubrication, cooling, and chip flushing in machining centers, lathes, milling machines, etc.
• High-Pressure Cooling Systems:​ Suitable for high-pressure coolant applications for lubrication, chip flushing, and cooling, such as deep-hole drilling, high-speed grinding.
• Industrial Cleaning Equipment:​ Liquid on/off control in spray and wash systems.
• Water Cooling Systems:​ Acts as a solenoid shut-off valve in industrial water cooling equipment, controlling the supply of cooling water or coolant.

IV. Installation & Usage Precautions

• Installation Direction:​ Arrow on valve body must align with medium flow direction. Do not install backwards.
• Line Cleanliness:​ Clean piping before installation to prevent welding slag, metal chips, etc., from entering and damaging seals.
• Filter Protection:​ Install a filter upstream of the valve to prevent debris from jamming the spool.
• Voltage Matching:​ Ensure power supply is DC24V with correct polarity to avoid coil burnout.
• Ambient Temperature:​ Avoid use in high-temperature, corrosive, or highly vibrating environments.
• Regular Inspection:​ Periodically check valve body and joints for leaks, and coil for overheating. Replace seals or coil as necessary.

V. Selection & Replacement Guidance

• Pressure Match:​ Ensure system pressure is within 0–3 MPa. Select a higher pressure rating if needed.
• Media Match:​ Confirm media is water or coolant. For oil, corrosive liquids, or gases, verify seal material compatibility.
• Voltage Match:​ Confirm control voltage is DC24V. Select corresponding model for AC or other voltages.
• Port Match:​ Confirm port size is 3/8″ Rc. Select corresponding model for other sizes/threads (e.g., change ’10’ to ’06’ or ’04’).

VI. Pricing & Procurement Reference

• Approx. Price:​ Around ¥1,850 per unit (MOQ ≥1 unit. Exact price subject to supplier quote).
• Procurement Channels:​ Available through SMC authorized distributors, industrial automation platforms, or e-commerce platforms (like 1688). Provide full model SGH130A-30G10Y-5WZ​ for inquiry.

VII. Distinction from “Cryogenic Valves”

SGH130A-30G10Y-5WZ is a coolant solenoid valve with a max. operating temperature of 100°C, intended for liquid control at ambient or moderately elevated temperatures, not​ for cryogenic systems.

• Cryogenic Valves:​ Typically used for media below -50°C or even -196°C. Require materials like low-temperature carbon steel or austenitic stainless steel, meet low-temperature impact test requirements, and often feature extended bonnets, self-venting designs, etc.
• Coolant Valves (“冷用阀”):​ In industrial automation, commonly refer to “coolant valves” for machine tool cooling, high-pressure cooling, etc. Media temperature typically ranges from 0 to 100°C, distinctly differing from cryogenic valves in materials, construction, and application temperatures.

Summary:

SGH130A-30G10Y-5WZ is a solenoid valve for liquids like coolant and water, operating at 0–3 MPa with DC24V power. Its main uses include machine tool cooling and high-pressure cooling. Ensure pressure, media, voltage, and port compatibility during selection. Pay attention to flow direction and line cleanliness during installation. Regular inspection and maintenance ensure long-term, reliable operation.
