Pressure Balanced Twin Plug Valve, API 6D/API 599, 1/2-16 IN

Key Specifications / Features

The Pressure Balanced Twin Plug Valve is manufactured to API 6D and API 599 standards. Available in sizes from 1/2 to 16 inches and pressure ratings from Class 150 to 1500 LB, this valve is constructed from various materials, including ASTM A216 WCB, A217 WC6, A352 LCB, and A351 CF8/CF8M/CF3/CF3M, ensuring compatibility with diverse media and operating conditions. Its pressure-balanced twin plug design reduces torque and enhances sealing performance.

The pressure-balanced twin plug valve is designed for reliable primary and secondary tight shutoff, ensuring system integrity. Traditionally, achieving system integrity required two separate isolation valves, a spool piece, and a bleed valve, leading to higher costs, increased weight, and a greater risk of emissions due to multiple flanged connections. This twin plug valve integrates dual plug valves within a single body, featuring a bleed valve positioned between them. Available in a bi-directional configuration, it offers both metal and rubber seat options, meeting ANSI Class VI standards for superior sealing performance.
