3 Piece Forged Steel Trunnion Ball Valve,2-48 IN,150-2500 LB

Forged Steel Trunnion Ball Valve

Forged Steel Trunnion Ball Valve - 3-Piece Design, Super Duplex Steel

The forged steel trunnion ball valve typically features a 3-piece body construction, making it ideal for various types of pipelines. It is designed to handle pressure ratings from Class 150 to 4500 LB, PN16 to PN720, and JIS 5K to JIS 40K. This valve is used to start or stop the flow of pipeline media and can be operated manually, by worm gear, pneumatic actuator, or electric driver. Available connection types include RF Flange, RTJ Flange, butt welding, and Grayloc.

TECHNICAL FEATURES
 

• Split Body, Forged Steel, Side Entry Trunnion Ball Valve
• 3-Piece Bolted Construction: Allows for easy disassembly in the field for maintenance and repairs.
• Isolated Stem Design: The stem is separated from the ball, eliminating side loads on the stem.
• Tight Shut-Off Sealing: Ensures a leak-proof performance.
• Explosive Decompression-Resistant Seal: Designed to withstand sudden pressure changes.
• Nickel Plating: Trim parts, including the ball and seat ring, are plated with 3 mil nickel for added durability.
• Trunnion Mounted Ball: Enhances operation under high-pressure conditions, with both post and plate designs available.
• Double Block & Bleed Capability: Provides enhanced safety and isolation.
• Fire-Safe Design: Ensures operation in fire conditions according to safety standards.
• Multiple Stem Seals: Offers additional leak protection.
• Double Isolation & Bleed (DIB) Design: Available for extra safety measures.
• Pressure Relief: SPE seats provide valve cavity pressure relief to prevent overpressure.
• Sealant Injection System: Built-in system for emergency seat and stem sealing.
• Anti-Provision Design: Prevents damage under adverse conditions.
• Anti-Static Device: Minimizes risks associated with static electricity.
• Blowout Proof Stem: Back-seated design to prevent stem blowout.
• Plastic Seat Inserts: Available in RPTFE, DEVLON, and PEEK for harsh applications.
