FONTAL PMS246-NB-D24G — 2-Position 4-Way Pneumatic Solenoid Valve, DC24V, NBR Seals

FONTAL · PMS Series · 2/4 Directional Valve · 24V DC Coil · In stock

The FONTAL PMS246-NB-D24G is an internally piloted, 2-position 4-way (5-port) pneumatic solenoid valve built around a DC24V coil and NBR elastomer seals. Designed for clean, lubricated or oil-free compressed air, it is a workhorse directional control element for machine builders and end-of-line pneumatic circuits. KOEED stocks the PMS246-NB-D24G as a drop-in replacement unit for the wide PMS series — ideal for spare-parts procurement, retrofit on legacy fixtures, and new assembly line build-out. Pair it with the discrete output modules of any major Allen-Bradley, Siemens, Mitsubishi, Omron or Schneider PLC to drive the coil directly from a 24V sourcing output.

Key Specifications

Datasheet Highlights

• Internally piloted 2/4 valve. Uses the supply pressure at port 1 to actuate the spool — no external air pilot signal required. Simplifies wiring and reduces the number of fittings in a fixture.
• 24V DC solenoid coil. The “D24G” suffix marks the standard continuous-duty 24V DC coil, suitable for direct connection to a 24V DC sourcing output of any modern PLC discrete module. The lower inrush of a DC coil also makes it quieter on contact wear than AC equivalents.
• NBR elastomer seals (NB). The standard NBR seal kit handles general-purpose compressed air within 0 to 50 °C ambient. NBR is the right pick for factory air and most lubricated or oil-free service; for chemical compatibility with aggressive fluids, a FKM (Viton) variant should be sourced instead.
• 5-port, 2-position function (4/2). Two working ports (2 and 4) feed a single-acting or double-acting cylinder, with exhaust through ports 3 and 5 in the de-energised state. Spring-return is the standard configuration — the valve returns to its default position the moment coil power is removed.
• Clean-air specification. Filtered air of 40 µm or finer is required to keep the spool bores from scoring. A typical upstream conditioning chain is FRL (filter + regulator + lubricator) with a 5 µm coalescing element on dirty shop-air lines.
• Spool-type, lapped metal-to-metal seating. Long service life under normal cycling duty. Spool and sleeve are field-replaceable; coil kits and seal kits are stocked separately for scheduled maintenance.

Typical Applications

The PMS246-NB-D24G is a general-purpose pneumatic directional valve. It is most often specified wherever a 24V DC logic output must directly drive an air cylinder, a rotary actuator, or a pilot signal to a larger process valve. Typical deployments include:

• Pneumatic cylinder actuation on assembly stations, jigs and fixtures, where the PLC drives cylinder extend / retract through a 24V DC output.
• Machine tool clamping and unclamping on CNC mills, lathes and machining centers, where a 4/2 valve feeds a single-acting clamp cylinder; commonly paired with FANUC spindle and servo systems on retrofitted cells.
• Packaging line pneumatic control — bottle indexing, label blow-off, carton flap closure, and diverter gates on conveyors. The 24V DC coil matches discrete output cards used in packaging machinery.
• Assembly automation cells driving pick-and-place pneumatic fingers, stopper cylinders, and escapement mechanisms at the heart of any factory automation work cell.
• Material handling and conveyor diverters in logistics sortation, where the valve serves as a low-power pilot for a larger flow-control device.
• Test stands and laboratory rigs in R&D environments that need a quick-replacement directional valve with a global 24V DC standard coil.
• Maintenance / MRO replacement of an OEM pneumatic valve in legacy systems where the original part is no longer available from the original machine builder.

Related Modules & Cross-Reference

The FONTAL PMS246-NB-D24G is a field device — it does not sit on a PLC backplane. What it must match, however, is the DC24V sourcing output of the controller that energises its coil. Below is a cross-reference of the discrete output modules most commonly paired with this valve across the nine KOEED brands. Always verify the pilot valve compatibility (current draw, inrush, surge suppression) and the polarity of the PLC output before wiring in production.

Selection tips:

• Confirm that the discrete output is 24V DC sourcing (PNP) rather than 24V DC sinking (NPN) — the FONTAL coil expects a sourcing driver.
• Check inrush current at switch-on (some DC coils briefly draw 2× holding current). If the per-point rating is tight, add an interposing relay.
• For vibration or inductive load, fit a flyback diode or surge suppressor across the coil terminals to protect the PLC output.
• When replacing an existing valve, capture the nameplate photo and share it via KOEED AI Diagnostic Tool for an instant cross-reference suggestion.

Warranty & Authenticity

• Tested before shipment. Each FONTAL PMS246-NB-D24G is inspected for coil resistance, insulation integrity, leak-down at rated pressure, and mechanical actuation before packing.
• Worldwide shipping. KOEED ships from Shenzhen / Hong Kong to North America, Europe, the Middle East, Southeast Asia and South America with DHL, FedEx, UPS and standard air-freight options.
• Quote within 24 hours. Send a single-line RFQ or a full BOM quotation request and our team will return availability and pricing on the next business day.
• B2B sourcing specialist. KOEED is an independent multi-brand China Sourcing Company. We are not the OEM of FONTAL, Allen-Bradley, Siemens, Mitsubishi, Omron, Schneider, Panasonic or KEYENCE, but we source against your specifications, verify the supply chain, and consolidate mixed-brand BOMs into a single shipment.
• Obsolete & hard-to-find parts. For legacy systems where the original pneumatic valve is no longer available, our sourcing team can often cross to a current-production equivalent or a quality refurbishment.
