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.

Key Features & Functions

» Optional Bore Patterns: Available in Venturi, Regular, Short, and Standard configurations.
» Metal-to-Metal Seated Design: Ensures durability and reliable sealing.
» Injection Grease Sealed Design: Provides enhanced sealing for the stem and seats.
» Fire-Safe Construction: Designed to meet fire safety standards for secure operation in critical applications.

Product Characteristics

» Inverted Pressure Balance Design: Ensures stable and balanced operation under varying pressure conditions from different directions.
» Enhanced Sealing Structure: Utilizes a specialized sealing mechanism to effectively prevent fluid leakage when the valve is in the closed position.
