Frequently asked questions
Common questions about ELV from 3G Electric.
What solenoid coil voltages does ELV offer, and how do I identify the correct replacement for my valve?
ELV stock 12V AC, 48V AC, 110V AC, and 230V AC solenoid coils. The correct voltage is determined by your control system and the existing coil part number stamped on the valve connector body. We hold coils across all standard voltages; cross-reference your valve model (e.g., ELV35002-12, ELV15012-16) with the required voltage to confirm compatibility before ordering. Coil plug styles are standardized within cavity families.
Are ELV valve replacement membranes available individually, and what material options exist?
Yes. ELV membranes are sold separately as wear parts—NBR (nitrile) is the standard elastomer offered for general air, water, and light-oil service. Membrane kits (SKU format ELV905xx) are indexed by valve cavity type (e.g., ELV90506 for ELV15012-25012 series). Verify your valve cavity size and pressure rating before ordering to ensure correct seal performance and cycle life.
Can I use a single ELV valve body with different coil voltages without mechanical changes?
Yes, within a cavity family. ELV solenoid coil cartridges are hot-swappable on the same valve body—you can replace a 230V AC coil with a 48V AC coil (or vice versa) using the matching cavity, provided the electrical connector type remains compatible. This modularity is useful for retrofit projects or when control voltage standards change on your plant floor.
What is the pressure and flow rating of typical ELV solenoid valve models?
ELV valve ratings vary by cavity design and model number. Small 2/2-way cavity valves (e.g., ELV05, ELV15 series) typically operate at 0–6 bar with flows under 50 L/min, while larger cavity designs (e.g., ELV35, ELV40, ELV50) accommodate 0–16 bar and flows up to several hundred L/min. Always cross-check your application's pressure and flow envelope against the specific model datasheet—We can provide full technical specs on request.
Do you stock ELV valve components for rapid replacement, and what is the lead time?
We hold 181 ELV SKUs including complete valves, solenoid coils, and sealing membranes. Common coil voltages (12V AC, 48V AC, 110V AC, 230V AC) and standard membranes are available in its Singapore warehouse, enabling same-day or next-day fulfillment for routine maintenance parts. Non-stock specialty orders are processed through established supply channels.
How do I determine whether an ELV valve is suitable for my fluid medium—air, water, oil, or gas?
ELV solenoid valves are designed for multi-fluid use (air, water, mineral oil, inert gases). Material compatibility is determined by the elastomer seals and internal spool finish. Standard NBR membranes suit general industrial media; for specialty fluids (e.g., aggressive oils, cryogenic gases, high-temperature steam), verify membrane and wetted-material compatibility with the valve datasheet or consult our technical support before installation.
