Product Description:
The 7FA Series is a direct-acting solenoid valve with a 3-way normally open configuration, engineered for accurate regulation of various media including air, water, steam, gas, and light oil. It is specifically designed for use in compressor and industrial systems where precise control is essential.
Constructed from durable brass or stainless steel, the valve boasts strong resistance against harsh operating conditions. It also offers a selection of seal materials such as NBR, EPDM, and FKM, allowing it to perform reliably across a broad temperature spectrum.
Its design incorporates a subplate mounting feature, which facilitates straightforward installation either within compact manifold assemblies or as an independent unit. Available orifice sizes range from 1.6mm to 4.0mm, and it can operate at pressures up to 15 bar.
Offering outstanding flow control capabilities, the 7FA Series is well-suited for challenging applications that demand rapid response times and operate with zero minimum pressure differential, ensuring efficiency and reliability in every use.
Features:
The valve features a 3-way, normally open (NO) direct-acting design, ensuring reliable performance and ease of operation. This configuration allows for efficient control of fluid flow in various applications.
Constructed primarily from brass as the standard body material, there is also an option for stainless steel to accommodate more demanding environments. This choice provides durability and resistance to corrosion.
The valve offers multiple orifice sizes—1.6mm, 2.5mm, 3.0mm, and 4.0mm—allowing flexible flow capacity tailored to different system requirements. Additionally, a common top orifice size of 1.5mm is maintained across all models.
It supports a pressure range from 0 up to 15 bar, with zero differential capability, meaning it can operate even at very low or no pressure. The exact maximum pressure tolerance depends on the selected orifice size.
To ensure compatibility with various media, the valve is equipped with multiple seal options including NBR (operating between -10°C to +80°C), EPDM (from -30°C to +120°C), and FKM (from -30°C up to +150°C). This makes it suitable for a wide range of fluids.
Voltage options are versatile, covering 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC at 50/60Hz frequencies, facilitating integration into different electrical systems.
The valve is designed for subplate (base) mounting, which is compact and simplifies maintenance efforts. This mounting style enhances serviceability and installation convenience.
Its broad media compatibility includes air, water, steam, gas, oil, and other non-corrosive fluids, making it applicable across a diverse range of industries.
Operated through direct-acting mechanics, the valve requires no minimum pressure to function, making it ideal for vacuum or low-pressure environments.
Finally, the valve delivers fast response times with quick opening and closing actions, thereby providing precise cycle control for dynamic system demands.
