Top Entry Ball Valve

What is the self-sealing method
of the top entry ball valve

When the operated device is rotated or moved, the valve stem transmits force to the valve ball, and causes the ball to rotate. By controlling the angle of rotation of the ball, the degree of opening and closing of the fluid passage can be controlled. When the spool is in full contact with the valve seat, the ball valve will be in a closed state, and the fluid cannot pass through; and when the spool is rotated to separate from the valve seat, the ball valve will be in an open state, and the fluid can pass through smoothly. And the ball and seat of the top entry ball valve adopts a special structure form, the sealing ability will be stronger, can effectively prevent fluid leakage.

Key Components of Top Entry Ball Valves

The top entry ball valve mainly consists of the following six parts. This component ensures that the top entry 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

Top Entry Ball Valves

01

Convenient maintenance

This valve is top entry design, the ball crown and support ball body from the upper part of the valve; Maintenance only need to open the valve cover to lift out the ball crown and support ball body can be repaired and sealing ring and other accessories, do not have to unload the entire valve from the pipeline, which gives the underground pipeline, especially industrial ball valves to bring a great deal of convenience.
02

Good sealing performance

The sealing ring between the ball and seat of the top entry ball valve can realize good sealing effect and effectively prevent fluid leakage. Especially the floating ball valve, its ball body to apply a compression spring, so that the seat sealing surface in any case are in close contact, good sealing performance.
03

Small Fluid resistance

The channel of the ball valve is relatively straight, the fluid through the resistance is small, can provide a larger flow. Full bore ball valve basically no flow resistance.
04

Easy to operate

The top entry valve structure is simple, small size, light weight. Easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 , easy to control from a distance.
05

High corrosion resistance

Top entry ball valves often made of corrosion-resistant materials, which can resist a variety of corrosive media . The designed of the top mounted inlet type ball valve, make it in the fully open or fully closed state, the sealing surface of the ball and the valve seat and the media isolation, and when the medium flows in high speed through the valve also will not cause the erosion of the sealing surface of the situation.

Why Choose Top Entry Ball Valves?

Lipin's top entry ball valve adopts sealing ring to realize sealing between ball and valve seat; Small flow resistance, reduce energy loss and improve efficiency; When maintenance is needed, the valve cover and valve stem can be disassembled from the top, saving maintenance time and reducing the impact on production; Easy to operate, the switch can be completed by rotating 90 to realize long-distance control; According to the need of different working conditions, choose the right material and structure to adapt to the different media and environmental conditions.

About Lipin Top Entry 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

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.
