What Is the ASCO FTX8320A021M010856 Solenoid Valve?

The ASCO FTX8320A021M010856 is an industrial-grade solenoid-operated valve with a 24–32 VDC coil and 1/4-inch port size. Manufactured in the United States by ASCO (an Emerson Electric brand and the world's leading solenoid valve manufacturer), it is built for pneumatic and fluid automation applications requiring fast, reliable switching with low DC power consumption. NSMP (New Surplus Military Part) designation indicates it was manufactured to military procurement standards for ruggedness and long service life.

In short: The ASCO FTX8320A021M010856 is a US-made, 24–32 VDC, 1/4-inch industrial solenoid valve — engineered for pneumatic and fluid control in automation systems, test rigs, and process equipment where dependable on/off flow control is critical.

Key Features and What They Mean

1. 24–32 VDC Wide-Range Coil

What it means: The solenoid coil accepts a DC input voltage from 24V to 32V, providing flexibility across different control system power rails.
Why it matters: Industrial DC control circuits commonly use 24 VDC — this valve integrates directly without an additional power supply or AC/DC converter.
Result: Simplified panel wiring, reduced component count, and compatibility with standard PLC digital output modules.

2. 1/4-Inch Port Size

What it means: The valve body features standard 1/4-inch NPT or BSP ports (verify from product label), fitting common pneumatic tubing and hydraulic hose sizes.
Why it matters: 1/4-inch is the most widely used port size in industrial pneumatic systems, making this valve a drop-in replacement for a broad range of existing installations.
Result: No adapters or custom fittings required in most applications — faster installation, fewer leak points.

3. ASCO Engineering Heritage — US-Made

What it means: Designed and manufactured in the United States under ASCO's quality system, widely regarded as the benchmark in solenoid valve reliability.
Why it matters: ASCO valves are specified in mission-critical applications — from power plants to pharmaceutical lines — where unplanned valve failure means production loss.
Result: Proven MTBF (Mean Time Between Failures), readily available technical documentation, and global service support through the Emerson network.

4. NSMP (New Surplus Military Part) Provenance

What it means: Manufactured under military procurement specifications, which typically require extended temperature range, vibration resistance, and documented material traceability.
Why it matters: Military-spec components are built to a higher durability standard than many commercial off-the-shelf equivalents.
Result: A robust valve you can deploy in demanding environments — outdoor installations, mobile equipment, and high-cycle automation cells.

Key Specifications

Typical Applications

• Pneumatic Actuator Control: Directs compressed air to pneumatic cylinders, rotary actuators, and grippers in automated assembly and packaging lines.
• PLC-Controlled Process Valves: Switched by a 24 VDC PLC digital output to control air or fluid flow in batching, dosing, and dispensing systems.
• Coolant / Lubricant Lines: Opens or closes coolant or cutting fluid flow in CNC machining centers and metalworking equipment.
• Test Rigs & Lab Automation: Provides precise, repeatable flow switching in hydraulic/pneumatic test benches and R&D experimental setups.
• Medical & Analytical Instrumentation: Suitable for gas and fluid handling in analyzers where reliable solenoid performance is mandatory.
• Compressed Air Blow-Off Systems: Controls timed air pulses for parts cleaning, drying, and ejection in high-speed production lines.
• Mobile Hydraulic Equipment: Military-spec robustness makes it suitable for vehicle-mounted hydraulic and pneumatic systems subject to vibration and temperature extremes.

Frequently Asked Questions

"Can I power this solenoid valve directly from a 24V PLC output?"

Yes, the FTX8320A021M010856 is designed for 24–32 VDC operation, which aligns with standard industrial PLC digital output modules. However, always check the coil inrush current against your PLC output card's maximum switching capacity. If the coil current exceeds the card rating, use an interposing relay. For exact wattage/current draw, refer to the ASCO datasheet for this specific model number, or contact Moritta@KOEED.COM for assistance.

"Is this valve normally open or normally closed?"

The NC (Normally Closed) or NO (Normally Open) configuration is stamped on the valve body or coil nameplate. ASCO FTX-series valves are available in both configurations — verify the marking on the unit you receive, or check the photos on this listing. If you need a specific configuration for your application, email Moritta@KOEED.COM before ordering and we will confirm.

"What does NSMP mean, and is this valve new?"

NSMP stands for New Surplus Military Part — it is a brand-new, unused valve manufactured to military procurement standards, typically as overstock from a defense contract or institutional purchase. It has never been installed or operated. KOEED verifies condition visually before listing; after you order, we will send photos and a video of the exact unit for your confirmation before shipping.

"What thread standard is the 1/4-inch port — NPT or BSP?"

ASCO valves manufactured in the United States typically use NPT (National Pipe Thread). However, this specific part number may use NPT or an alternative standard. The thread type is usually marked on the valve body adjacent to the port. We recommend checking the listing photos or contacting us at Moritta@KOEED.COM for confirmation if your application requires a specific thread standard.

"What media can flow through this valve?"

ASCO solenoid valves are commonly rated for air, inert gases, water, and light oils. The exact media compatibility depends on the valve body material (typically brass or stainless steel) and the internal seal material (NBR, FKM, EPDM, or PTFE). Verify the seal material from the product label or datasheet before using with aggressive chemicals, high-temperature fluids, or food-grade media.
