Product Description:
The 8.7AA Series is a 2/2-way normally closed direct-acting solenoid valve specifically designed for high-pressure fluid control applications up to 300 bar (4,300 PSI). It offers dependable ON/OFF control suitable for various media including water, air, gas, and other neutral liquids.
This valve is built to perform exceptionally well in demanding environments that involve high pressure and elevated temperatures. Its direct-acting mechanism guarantees consistent operation even from zero differential pressure, making it an ideal choice for applications that require precise control throughout the entire pressure range.
Constructed with a robust Stainless Steel 304 body and equipped with PTFE seal material, the 8.7AA Series ensures excellent durability, corrosion resistance, and leak-tight integrity under extreme conditions. It is designed to withstand harsh environments while maintaining reliable performance.
The valve is available with port sizes varying from 1/8″ to 1/2″ and orifice dimensions between 1mm and 3mm, offering versatile flow control capabilities. With Cv values ranging from 0.03 to 0.25, it can be tailored to meet diverse operational requirements.
Manufactured in Ningbo, China, the 8.7AA Series solenoid valve is recognized worldwide for its quality and reliability in high-pressure fluid systems.
Features:
The valve is designed to handle demanding high-pressure environments, with a maximum working pressure reaching up to 300 bar (4,300 PSI). This makes it suitable for applications that require robust and reliable performance under intense pressure conditions.
It supports a wide temperature range, compatible with media temperatures from as low as -60°C to as high as +200°C. This versatility allows the valve to operate effectively in both cryogenic and high-temperature scenarios.
Featuring a direct acting operation with a spring-return mechanism, the valve can function starting from zero differential pressure (0 bar). This ensures dependable performance throughout the entire pressure spectrum.
The valve operates as a 2/2 way normally closed unit. Thanks to its spring-return design, it remains closed when de-energized, providing a fail-safe operation that enhances safety and reliability.
Constructed with a premium Stainless Steel 304 body, the valve offers outstanding corrosion resistance and structural strength. This durable construction is ideal for long-term use in harsh and challenging environments.
Equipped with high-performance PTFE seals, the valve delivers excellent leak-tightness, chemical resistance, and thermal stability. These features ensure consistent and safe operation across various demanding conditions.
To provide precise flow control, multiple orifice sizes are available, including 1mm, 1.5mm, 2mm, 2.5mm, and 3mm. Correspondingly, the Cv values range from 0.03 to 0.25, allowing for tailored performance according to specific application needs.
The valve also offers a wide selection of port sizes—1/8″, 1/4″, 3/8″, and 1/2″—ensuring flexible integration into various system configurations.
It supports multiple voltage options such as 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC (50/60Hz), making it compatible with a broad range of control systems and applications.
Backed by a strong production capacity, the manufacturer can reliably supply up to 500,000 units annually and 5,000 units weekly. This ensures availability for bulk orders and consistent supply chain management.
