Didtek F51 Trim Metal To Metal F60 Trunnion Ball Valves Hard Seal

Product Overview

A high-performance and highly reliable valve specially designed to cope with extremely harsh working conditions. It adopts F60 duplex stainless steel as the valve body and F51 duplex stainless steel as the key internal components, and combines metal hard seals and fixed spherical structures, perfectly solving the challenges faced by valves in high-pressure, corrosive, wearing and high-temperature environments, ensuring the long-term stable operation of the system.

Product Name Analysis

F60: Refers to the main material of the valve, which is a high-performance duplex stainless steel, equivalent to UNS S32205. It has excellent resistance to chloride stress corrosion cracking, pitting and crevice corrosion, and its mechanical strength is much higher than that of ordinary austenitic stainless steel.

F51 Trim: Refers to the material of the internal components of the valve.

Trim: In valve terminology, it specifically refers to all moving parts that come into contact with fluids, mainly including valve seats, ball sealing surfaces, etc.

F51: It is another type of duplex stainless steel, equivalent to UNS S31803. Its corrosion resistance is slightly lower than that of F60, but it has excellent overall performance and is cost-effective as an internal component material.

Metal To Metal Hard Seal: Metal hard seal. The sealing pair between the ball and the valve seat is all made of metal materials. This is in contrast to the "soft seal" that uses soft materials such as PTFE, and is suitable for high-temperature, high-pressure and particle wear conditions.

Trunnion Ball Valves: Fixed ball valves. The sphere is supported by two fixed shafts at the top and bottom. It will not shift under high pressure, so the operating torque is small and the sealing performance is stable. It is specially designed for high-pressure and large-diameter working conditions.

Core features and advantages

Outstanding corrosion resistance

Both the valve body of F60 and the internal components of F51 are made of duplex stainless steel, which has extremely strong resistance to chloride stress corrosion, pitting corrosion, crevice corrosion and various acidic media. They are especially suitable for corrosive environments such as seawater and chemical media.

Extremely high reliability and long service life

The fixed structure ensures low torque and zero leakage under high pressure.

The metal hard seal design enables the valve to maintain excellent sealing performance even at high temperatures (far exceeding the limit of soft seals) and in abrasive media containing solid particles.

Applicability to high pressure and large diameters

The Trunnion fixed design is the preferred choice for high-pressure pipelines and large-diameter applications. Its mechanical structure can effectively counteract fluid pressure, prevent ball offset, and ensure long-term effective sealing of the valve seat.

Optimized cost-effectiveness

By adopting the combination of "F60 valve body + F51 internal components", high-performance materials are used in key sealing and corrosion-resistant parts, while more cost-effective materials are applied to the main structural body, achieving a perfect balance between performance and cost.

Typical application fields

This valve is an ideal choice for the following harsh working conditions:

Oil and gas: Offshore platforms, high-sulfur oil and gas fields, gathering and transportation pipelines, natural gas processing plants.

Chemical Engineering and petrochemicals: Process pipelines for highly corrosive chemicals (such as acids, alkalis, and solvents).

Energy and Power: Flue gas desulfurization system, seawater cooling system.

Marine engineering: Ship ballast systems, seawater pipelines.

Mining and Metallurgy: Slurry conveying pipelines, treatment of corrosive media in metallurgical processes.
