Welded Y-type forged steel stop valves are high-performance stop valves suitable for high-pressure and high-temperature conditions in various industrial fields.

Definition and Application

Welded Y-Type Forged Steel Check Valves are a type of check valve connected by welding, primarily used in industries such as oil, chemicals, fertilizer, and electricity. They are suitable for cutting off or connecting media like water, oil products, steam, and acidic media.

Design and structural features

Design features of the焊接Y型锻钢截止阀 include:

The valve body and cover are焊接connected to ensure sealing and strength.

The sealing surface is made of Stellite hard alloy, offering wear-resistant, corrosion-resistant, and friction-resistant properties, thus extending the service life.

The valve rod has been heat treated and surface nitrided, enhancing its corrosion and friction resistance.

Utilizing a bellows-sealed design, it eliminates the drawback of rapid aging and leakage in the packing of ordinary valve stems, enhances energy efficiency, and boosts the safety of production equipment.

Application Scenarios and Advantages

Welded Y-Type Forged Steel Check Valves are suitable for the following scenarios:

High-pressure and high-temperature conditions, such as deep-sea platforms and Sinopec pipelines.

Low flow resistance design, reducing pressure drop of the medium in the pipeline.

‌Extended sealing life, tested for 100,000 cycles of opening and closing, ensuring long-term stable operation.‌

‌Smart operation experience, the low-torque design enhances operational efficiency._
