Product Description

MN Series Urea-Specific High-pressure Regulating valve

The components of this series valve is maximally constructed from stainless steel.The upper valve body has an integral forged special stainless steel structure to avoid any corrosion caused by environmental conditions.

The bonnet adopts a monobloc design, avoiding flange connections and dead zones. Its streamlined flow channels design and integrated valve core-valve stem structure ensure superior and reliable valve performance.

The MN series urea-specific high-pressure regulating valves is standardly equipped with a pneumatic diaphragm actuator. For higher thrust requirements, a heavy-duty spring-return cylinder actuator can be optionally selected based on actual working conditions. Meanwhile, a side-mounted worm gear handwheel or top-mounted manual hydraulic pump is available as an option to ensure smooth, long-term, and reliable valve operation in specific working conditions.
