Pressure Balance Lubricated Plug Valve – ANSI Class 150 to 1500, Inverted Design, TEJI

The Pressure Balance Lubricated Plug Valve by TEJI is engineered for reliable flow isolation in critical pipeline systems across industries such as petroleum refining, chemical processing, pharmaceuticals, fertilizers, and power generation. Designed with an inverted pressure balance structure, this valve ensures easy opening and closing under high pressure while maintaining superior sealing capabilities.

This plug valve operates under nominal pressure classes from 150 to 1500 LBS and withstands working temperatures from -29°C to 550°C, making it ideal for both standard and high-temperature fluid service. Its flip-chip pressure balance mechanism eliminates operational torque strain, providing smooth actuation across its lifespan.

A seal grease injection groove between the valve body and seat surface allows for the infusion of sealing lubricant, greatly enhancing its leak-tight performance even in demanding conditions. With a robust structure, aesthetic finish, and compact form, this valve offers reliable performance and long service life in corrosive or high-pressure environments.
