Product Overview

The Earth Star brass compression solenoid valve is engineered to meet the demanding requirements of industrial and scientific applications where precise fluid control is essential. Crafted from high‑quality brass, the valve offers exceptional resistance to corrosion, ensuring a long service life even in harsh environments. The exterior finish matches the brass construction, providing a uniform appearance that complements a wide range of equipment aesthetics.

Designed with a single 8.5 mm port, the valve features both inlet and outlet compression connections, simplifying installation and reducing the risk of leaks. The compression spring is calibrated to 3.0 N ±10%, delivering consistent opening and closing forces across the specified temperature range of –10 °C to 120 °C. This robust spring mechanism, combined with a coil resistance of 18 mΩ ±15%, guarantees reliable operation under varying electrical conditions.

Electrical performance specifications include an opening current of up to 180 mA and a closing current of at least 20 mA, making the valve suitable for low‑power control circuits. The compact dimensions—2.72 × 1.54 × 0.59 inches—and lightweight design (0.352 oz) enable easy integration into space‑constrained assemblies without sacrificing durability.

Each package contains two valves, providing a convenient solution for projects that require multiple units or spare parts. The part number SMT‑DF001 and UPC 671423831290 ensure accurate identification and inventory management, while the ASIN B073R973S6 facilitates online ordering and tracking.

Customer feedback highlights a 4.4‑star rating from over 200 reviews, reflecting consistent satisfaction with performance, build quality, and value. Ranked #13 in the Sheet Gaskets category and #56,681 in Industrial & Scientific overall, the valve has earned a solid reputation among professionals seeking dependable flow control components.

Usage

This solenoid valve excels in applications such as pneumatic and hydraulic systems, laboratory equipment, and sheet gasket assemblies where precise regulation of fluid or gas flow is required. Its brass construction makes it ideal for environments exposed to moisture, chemicals, or temperature fluctuations, as the material maintains structural integrity and prevents contamination of the conveyed medium.

In manufacturing settings, the valve can be incorporated into automated assembly lines to control air pressure for actuators, ensuring synchronized motion and reducing cycle times. The compression connections allow for quick swaps and maintenance without the need for specialized tools, minimizing downtime during routine servicing.

For scientific instrumentation, the valve provides a stable platform for experiments that demand accurate dosing of gases or liquids. The wide operating temperature range supports use in climate‑controlled chambers, while the low electrical current requirements enable integration with sensitive measurement equipment that cannot tolerate high power draw.

Field technicians appreciate the valve’s straightforward installation process, which involves simply tightening the compression fittings to achieve a secure seal. The 8.5 mm port size aligns with standard tubing dimensions, facilitating compatibility with existing infrastructure and reducing the need for additional adapters.

Because the valve does not require batteries and operates directly from the control circuit, it offers a maintenance‑free solution that reduces long‑term operational costs. Its reliable performance under continuous cycling makes it a preferred choice for systems that demand high duty cycles and minimal failure rates.

FAQ

What type of fluid can be used with this brass solenoid valve?

The valve is suitable for a variety of gases and liquids that are compatible with brass components. Common applications include air, nitrogen, inert gases, and non‑corrosive liquids such as water or oil. Users should avoid highly acidic or alkaline fluids that could react with the brass material.

How do I install the compression fittings correctly?

Begin by cutting the tubing to the appropriate length and ensuring a clean, square cut. Insert the tubing into the compression fitting, then tighten the nut by hand until it is snug. Use a wrench to give an additional 1‑2 turns, which creates a secure seal without over‑tightening. Verify the connection by checking for leaks under low pressure before full system operation.

Can this valve be used in high‑frequency cycling applications?

Yes, the valve is designed to handle frequent actuation cycles. The brass body and compression spring are engineered to withstand repeated mechanical stress, and the coil resistance is optimized for consistent electrical performance. For extremely high‑frequency demands, it is recommended to monitor temperature rise and ensure adequate cooling.

What maintenance is required to keep the valve operating optimally?

Regular inspection of the compression fittings for signs of wear or looseness is advisable. If the valve is exposed to dusty or particulate‑laden environments, periodic cleaning of the inlet and outlet ports can prevent blockage. The valve does not contain internal seals that require replacement, so routine maintenance is minimal.

Is the valve compatible with standard control voltage levels?

The solenoid coil is designed for typical low‑voltage control circuits, such as 12 V or 24 V DC systems. It can be driven directly from a relay or transistor output, provided the current specifications (≤180 mA opening, ≥20 mA closing) are respected. Always consult the datasheet for exact voltage and current ratings before integration.
