Buy Stainless Steel H12W-16P Check Valve PN16 Internal Thread Spring Type Vertical Design
The H12W-16P Vertical Spring Check Valve by VALVEHU is a high-performance stainless steel valve designed for vertical pipeline installations in demanding industrial environments. This spring-loaded non-return valve ensures efficient one-way flow of media such as water, oil, and other non-corrosive or mildly corrosive liquids, up to a maximum operating pressure of 16MPa.
Manufactured using high-grade materials including brass, SS304, SS316, and SS316L, this check valve delivers excellent corrosion resistance and long service life in temperatures up to 300°C. The threaded connection (ZG standard) makes it suitable for easy installation in compact piping systems where space is a constraint. Common applications include chemical processing, fluid distribution, HVAC systems, and high-pressure water lines.
The compact design features a built-in spring mechanism that provides quick closing action, minimizing backflow and water hammer. Its vertical orientation is optimized for systems requiring vertical flow control, maintaining steady pressure and safe system performance. With size availability ranging from DN15 to DN50 and standard thread sizes from 1/2″ to 2″, this valve is flexible across a wide range of flow capacities.
The H12W-16P is precision-engineered to comply with industry standards for performance and reliability. The detailed dimensions (H & L) ensure compatibility with global pipeline designs and installations.
Whether you are looking to upgrade existing pipeline systems or integrate reliable backflow protection into new installations, this vertical check valve delivers functionality and efficiency.
