Why choose Lipin Soft Seal Plug Valves?

Lipin Soft Seal plug valves are precision manufactured with advanced grinding technology to ensure high roundness and excellent surface quality. Due to the self-lubricating properties of the soft sealing material, the valve has excellent sealing performance. This design overcomes common problems with traditional metal sealed plug valves, such as leakage, high torque, and poor corrosion resistance. The seat and plug perform well, wear resistance and long service life, 2-4 times longer than titanium or Monel.

Performance advantages

All parts in contact with the medium are made of advanced soft sealing materials, with high chemical stability, hardness, wear resistance and corrosion resistance.
Material diversity

In addition to traditional materials such as carbon steel, Inconel and Monel, valve plugs can also be made of advanced materials such as PTFE and rubber to extend the service life of the valve.
Wide range of applications

Ideal for industries such as power, petroleum and chemical processing, especially in challenging environments with high wear, strong corrosion, high temperature and high pressure.
Excellent quality

Lipin adheres to high quality standards and minimizes maintenance requirements.
Efficient operation

The soft-seal plug valve is compatible with manual, electric, pneumatic and hydraulic actuators, significantly increasing operating efficiency.
Top Service team

Key Components of Soft seal plug valve

The Soft seal 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

guides medium flow and provides structural support.

Cock

Cock allows medium to pass through or precisely block.

Stem

Turn the cock 90° for quick opening and closing.

Seat

Contact the cock to create a secure seal, activated by upstream pressure.

Sealing surface

includes soft seals to meet various application requirements.

Actuator

Control the movement of the valve stem, adjust the position of the cock, and achieve effective flow control.

Advantages of

a soft seal plug valve

01

Improved tightness

Enhances the tightness of industrial piping systems to minimize leaks and protect the environment.
02

Cost-effective materials

Soft sealing materials such as PTFE and rubber are cost-effective and readily available, saving the use of metals and rare minerals.
03

High quality valve stem

The valve stem material conforms to national standards, and has good mechanical properties after fine polishing and corrosion resistance treatment.
04

Seal stability

Built-in elastic gasket, even in the media containing impurities can ensure stable sealing performance, prevent the valve plug stuck or broken.
05

Excellent performance

high temperature resistance, wear resistance, excellent corrosion resistance, good sealing and thermal conductivity.

Why choose a soft seal plug valve?

The soft sealing material has small deformation, high bonding strength, and high tensile strength, compressive strength and hardness. Advances in material technology have greatly improved the toughness and strength of soft seal plug valves. The application range of these valves is expanding, becoming more active in petroleum, chemical, machinery and other fields.

About Lipin Soft Sealing 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 hard-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.
