Why Choose Lipin's Trunnion Ball Valve

Trunnion ball valves can adapt to high pressure and large pipe diameters. So far, the most popular use of trunnion ball valves is in pipeline services, particularly suitable for natural gas pipelines with diameters up to 60" and pressures up to Class 600. By using trunnion design, the torque required to open and close the valve is lower, so smaller actuators can be used.

Anti spray design

This design prevents the valve stem from spraying out from the valve body due to improper operation.
Diverse and high-quality materials

We provide a variety of anti-corrosion and high-temperature resistant materials, not only traditional carbon steel, but also more advanced materials, like Inconel and Monel.
Wide applicability

Lipin's trunnion ball valve plays an important part in natural gas, chemical industry, power plants and other fields.
Highlighting good quality

We focus on details and precision in the manufacturing process, adopting advanced technology and processes to ensure valve reliability and extend service life.
Multiple driving modes

The trunnion ball valve can be matched with manual, worm gear, pneumatic atcuator, electric atcuator, hydraulic atcuator, gas-liquid linkage atcuator, and electro-hydraulic linkage atcuator.

Key Components of Trunnion Ball Valves

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

Valve Body

Guides the flow of media.

Sphere

The medium passes through or is intercepted by the sphere.

Valve stem

Drives the ball to open and close quickly through 90° rotation.

Valve seat

Contact with the ball to form a seal.

Sealing surface

Soft seal and metal seal.

Actuator

The movement of a valve that controls the valve stem.

Advantages of

Trunnion Ball Valves

01

Double blocking and discharge function

Regardless of whether the trunnion ball valve is in a fully opened or closed state, the seat on the upstream and downstream sides block the fluid, and the trapped substances in the valve body cavity are discharged through the discharge valve.
02

Automatic pressure relief function

When the temperature of the medium in the valve chamber rises and causes abnormal pressure rise, the seat function alone can automatically relieve pressure, which is very important to ensure the safety of the valve when conveying liquid medium.
03

Valve stem can be extended

The valve stem can be extended according to installation or operation needs. Extended rod ball valve, especially suitable for urban gas and other occasions that require buried pipeline laying.
04

Flexible operation

The use of valve seat and valve stem bearings with small friction coefficient and good self-lubricating properties greatly reduces the operating torque of the valve. Therefore, even without providing sealing grease, the valve can be operated flexibly and freely for a long time.
05

Reliable valve stem seal

The dual seal ensures the reliability of the valve stem seal; The addition of graphite packing and sealing grease injection minimizes valve stem leakage after a fire.

Why Choose Trunnion Ball Valves?

The trunnion ball valve adopts a double piston effect design, and the pressure acts on the outer side of the end of the valve seat sealing ring, forming an effective seal between the seat sealing ring and the body. When fully open and fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface.

About Lipin Trunnion Ball Valve

Valve Body Type :

Ball
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 ball 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.
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 150-2500（ASME standards）or PN10~PN420
Actuator:

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

1/2'' to 60'' (DN 15-1500)
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.
