Why choose Lipin Metal Seal Plug Valves?

Lipin's Metal-sealed plug valves are manufactured using state-of-the-art grinding equipment and technology. The spool exhibits high roundness precision and exceptional surface quality. Following the grinding process for both the spool and seat, advanced materials with self-lubricating properties are employed to achieve outstanding sealing performance. The valve overcomes common drawbacks associated with metal sealed plug valves such as leakage, high torque requirements, and poor corrosion resistance. Both the seat and spool demonstrate remarkable wear resistance and service life that is 2-4 times longer than titanium or Monel valves.

Performance Advantages

All components in contact with the medium are constructed from highly stable and rigid materials boasting excellent wear and corrosion resistance.

Key Components of Metal-sealed plug valve

The Metal-sealed plug valve mainly consists of the following six parts. This component ensures that the plug valve remains efficient and stable during operation and maintains a zero leakage record.

Valve Body

Guide medium flow.

Cock

Control medium flow by opening or blocking channels.

Stem

Rotate the cock to quickly open or close the valve.

Seat

Seal with cock to prevent leakage.

Sealing surface

Made of durable material to ensure tight sealing.

Actuator

Controls the movement of the valve stem and adjusts the position of the cock.

Why choose a Metal sealed plug valve?

Metal-sealed plug valves are made of advanced materials with minimal deformation and high bonding strength. The small ionic radius and high ionic charge of the crystal make the valve have excellent tensile strength, compressive strength, elastic modulus and hardness. Advances in toughening technology and nano-ceramics have significantly increased the toughness and strength of these valves, broadening their range of applications. Metal sealed plug valve is used more in petroleum chemical machinery industries because its performance reliability."

About Lipin Metal-sealed plug valve

Valve body type:

Plug
Valve body material:

Cast WCB carbon steel (general application), forged A105 carbon steel (general application), 304/316 stainless steel, alloy (corrosion resistance, extreme conditions), etc.
Valve stem material:

When the valve body material is ordinary carbon steel, the valve stem material is usually CR13 series martensitic stainless steel (American standard 410 and 420 stainless steel materials) or higher-grade austenitic stainless steel materials. When the valve body material is stainless steel, the valve stem material is usually austenitic stainless steel (American standard SS304, SS316) with a grade no lower than the valve body material and a higher grade corrosion-resistant alloy material (Hastelloy, Monel, Inconel alloy) etc.
Valve Disc material:

The valve stem material is basically the same as the valve ball, plus carbon steel electroplating ENP anti-corrosion material, unless there are special requirements. The material of the ball is also ZrO2, AI2O3, SiC, Si3N4, etc.
Seat material:

The Metal-sealed metal valve seat and fixed soft-sealed valve seat support ring of the ball valve should be made of the same material as the ball.
Seat sealing surface material:

The valve seat material is basically the same material as the ball, except for special requirements.
Pressure level:

Class 150-600（ASME standards）or PN10~PN100
Actuator:

Manual handwheel, electric actuator, pneumatic actuator, hydraulic actuator
Sizes:

1/2'' to 20'' (DN 15-500)
Temperature:

Depending on the material used, operation can occur within a temperature range of -50°C to +400°C, although specific materials may alter this range.
