Product Description:
The 8.7BA Series is a 2/2-way normally closed piston pilot-operated solenoid valve, specifically designed for high-pressure fluid control applications reaching up to 350 bar (5,000 PSI). It is engineered to provide reliable ON/OFF control for various media including water, air, gas, and other neutral fluids, ensuring exceptional performance even in challenging high-pressure and high-temperature settings.
This valve’s piston pilot-operated mechanism requires a minimum differential pressure of 5 bar to function effectively. Such a design makes it particularly suitable for medium to large diameter piping systems that demand a high flow capacity. The robust construction includes a Stainless Steel 304 body complemented by an advanced PEEK seal material, which together guarantee outstanding durability, excellent corrosion resistance, and leak-tight operation under extreme pressure and temperature conditions.
Available in port sizes from 1/8″ to 1/2″, and featuring a standard 8mm orifice, the 8.7BA series offers reliable and precise flow control suitable for a broad spectrum of industrial applications. Manufactured in Ningbo, China, this valve is globally recognized for its quality and dependable performance within high-pressure systems.
Features:
The valve offers an impressive high-pressure capability, with a maximum working pressure reaching up to 350 bar (5,000 PSI). This makes it well-suited for various demanding high-pressure applications where reliability is critical.
It is designed to operate efficiently over a wide temperature range, from as low as -60°C up to +300°C. This versatility allows it to function reliably in both cryogenic and high-temperature environments, meeting diverse industrial needs.
Featuring a piston pilot operated design, the valve benefits from pressure-assisted operation. This design ensures dependable switching performance, requiring a minimum differential pressure of only 5 bar to operate effectively.
The valve incorporates a 2/2 way normally closed function with a spring-return mechanism. This ensures that the valve remains securely closed when de-energized, providing fail-safe operation to enhance system safety.
Constructed from premium Stainless Steel 304, the valve body offers exceptional corrosion resistance and robust structural integrity. This high-quality material choice guarantees long-term durability even in harsh environmental conditions.
Advanced PEEK seal materials are utilized to deliver outstanding leak-tight performance along with excellent chemical resistance. These seals also maintain thermal stability, ensuring reliable operation under extreme conditions.
To accommodate various system requirements, the valve is available in a wide range of port sizes, including 1/8″, 1/4″, 3/8″, and 1/2″. This flexibility enables easy integration into multiple applications.
Each model features a standard 8mm orifice that provides consistent and reliable flow control. This uniformity helps maintain stable performance across the entire product range.
Multiple voltage options are supported, including 12VDC, 24VDC, 24VAC, 110VAC, and 220VAC (50/60Hz). This wide compatibility allows the valve to be used with various control systems worldwide.
Manufacturing is supported by a high production capacity, with the ability to produce 500,000 pieces annually and 5,000 pieces weekly. This ensures a steady and reliable supply for large-scale orders and bulk demand.

Support and Services:
Our Pneumatic Solenoid Valves are engineered to provide reliable and efficient control of air flow in various industrial applications. To ensure optimal performance, it is important to follow the installation and maintenance guidelines provided in the product manual.
For installation, make sure the valve is mounted in the correct orientation and that all connections are secure and free of debris. Use clean, dry air to prevent contamination and valve malfunction. Avoid exposing the valve to extreme temperatures and corrosive environments unless specified by the model specifications.
Regular maintenance includes periodic inspection of the valve coil, seals, and moving parts to detect wear or damage. Clean the valve components with appropriate solvents and replace any worn parts promptly to avoid operational failures. Lubrication is generally not required, but if specified, use only recommended lubricants.
If you experience any issues such as the valve failing to actuate, excessive noise, or air leakage, consult the troubleshooting section of the manual. Common causes include electrical supply problems, coil burnout, or clogged ports. Replacement parts and repair kits are available to restore valve functionality.
For system integration support, our technical team can provide guidance on valve selection, sizing, and compatibility with your pneumatic system. We also offer training sessions and detailed documentation to help you maximize the performance and lifespan of your Pneumatic Solenoid Valve.
