High Velocity P/V Relief Valve

Product catalog summary
General Description
The U-ISO-H/V/G series high velocity pressure/vacuum valve is engineered to prevent flame passage into cargo tanks and manage overpressure or vacuum conditions during various operations such as loading, discharging, and thermal changes. These valves are designed to be non-hammering, non-condensate accumulating, and non-corrosive, making them suitable for marine cargo tanks. They comply with IMO MSC/Circ. 677/1009, ISO 15364, and USCG vapor control system regulations.

Basic Rule Requirements
The valves adhere to several international standards and regulations, including IMO MSC/Circ.1009, IMO MSC/Circ.677, and ISO 15364, among others.

Material Specifications
The valve components are made from materials such as ductile cast iron, carbon steel, and stainless steel 316/316L, ensuring durability and resistance to corrosion.

Dimension Table
The document provides a detailed dimension table for various models of the U-ISO-H/V/G series, specifying measurements such as height, length, and weight for each model.

Benefits
The U-ISO-H/V/G series offers several advantages, including easy full stroke check lifting, no need for greasing, low forced hinged check lifting, replaceable disc and seat, adjustable settings, and visible disc operating positions.

Optional Arrangements
There are optional arrangements available, including electric heating type, steam tracing type, and a version for special chemicals with high vapor pressure.

Conclusion
The U-ISO-H/V/G series valves are designed with safety and environmental considerations in mind, offering advanced features and compliance with international standards.
