High Pressure Plug Valve

NSV High Pressure Plug Valve

Designed for severe service in oil & gas, LNG, and chemical industries, this plug valve provides reliable shut-off under high pressure and corrosive conditions. The body is cast from ASTM A995 duplex stainless steel for superior strength and corrosion resistance.

Key Features

Body Material Cast ASTM A995 Gr. 4A / 5A / 6A duplex stainless steel (optional)

Operation Gear

Pressure Rating Class 150 to Class 1500 (PN20 to PN250)

Size Range 1/2" to 20" (DN15 to DN500)

Valve Type Full port, straight-through plug valve

Design Standard API 607

Operation & Advantages

The valve opens and closes with a 90° turn via gear operation, suitable for high-torque applications up to Class 1500. The full-port design ensures minimal pressure drop and unrestricted flow. Soft-seated construction provides bubble-tight shut-off, while the duplex stainless steel body resists pitting, crevice corrosion, and sulfide stress cracking.

Typical Applications

LNG terminals, offshore platforms, sour service pipelines, seawater systems, and chemical processing plants requiring manual reliability and corrosion resistance.

Quality Control & Service

Valve design and manufacturing comply with ASME B16.34, and sealing performance is verified through API 607 fire-safe testing. A complete compliance documentation package is provided with each shipment. Our technical team provides support for installation and field assistance.
