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 tasks. It can operate efficiently under pressures up to 350 bar (5,000 PSI), making it ideal for demanding applications requiring robust and dependable valve performance.
This valve is engineered to provide reliable ON/OFF control for a variety of media, including water, air, gas, liquids, and other neutral substances. Its piston pilot-operated mechanism needs a minimum differential pressure of 5 bar to function, which makes it particularly suitable for medium to large diameter pipeline systems that demand high flow capacity.
Constructed with a Stainless Steel 304 body, the valve boasts excellent strength and corrosion resistance. It also incorporates advanced PEEK seal material, enhancing its durability and ensuring leak-tight operation even under extreme pressure and temperature conditions.
The 8.7BA Series comes with port sizes ranging from 1/8″ to 1/2″ and features a standard 8mm orifice. This flexibility allows it to deliver reliable flow control across a broad spectrum of industrial applications. Manufactured in Ningbo, China, this valve is recognized worldwide for its quality and dependability in high-pressure system solutions.
