Key Specifications / Features
The Lubricated Plug Valve, manufactured to API 599 and ASTM A105N standards, features a 2-inch (DN50) size, Class 2500 LB, and PN420 pressure rating. It incorporates an inverted pressure-balanced structure for enhanced sealing and performance. The valve is equipped with NPT threaded ends for secure and leak-proof connections, making it ideal for high-pressure applications.
The NPT Threaded End Lubricated Plug Valve is also referred to as the Inverted Pressure Balanced Lubricated Plug Valve. These valves can be designed to adhere to ANSI standards, with customization options available to meet the specific needs of the customer.
NPT End Lubricated Plug Valves are known for providing cost-effective, quick opening and closing operations with a tight, leak-proof seal. They are designed with a standard rectangular port and come with threaded end connections, available in sizes ranging from 1/2 Inch to 4 Inch.
The key difference lies in the interchangeable names (NPT Threaded End Lubricated Plug Valve vs. Inverted Pressure Balanced Lubricated Plug Valve) and the specific customization options available, allowing for flexibility in design and end connections.
