Introduction to Top Entry Ball Valve

The top entry ball valves are a valve with a ball sealed in the center of the valve that is mounted at the top of the spindle.

Top entry high performance ball valves like the ones we offer are a popular and reliable choice. They operate at any angle and are designed to handle full bore or reduced bore pipeline sizes. Trunnion mounted top entry ball valves can also be used for an array of applications including gas, oil, water, sewage and more.

Top entry Ball valves range with the single- and double-piston seat valves, along with a variety of seal types, to provide an effective double block and bleed (DB&B) in both closedand in open position.

Top Entry Ball Valves are used to control the flow of liquid or gas into a pipe, tank, or other vessel.

Construction Materials and Features

Features a top entry design for easy and natural placement, this ball valve has a corrosion and chemical resistant flow control knob and a self-aligning spherical seat valve that can be easily serviced. The valve is made with high-quality materials that are durable for long-lasting use.

Body Configurations

Top entry ball valve body configurations include full bore, Reduced Bore, and a variety of materials including stainless steel, carbon steel,forged steel etc.

top entry ball valves for managing gas, oil, and water services.

Other Option Features

Fire-safe

The valves are manufactured and tested to fire safe API 607/API 6FA to assure the operation available in case of fire.

Antistatic

The top entry ball valve is a new generation of the valves, with an anti-static design and a simple structure, it is highly reliable and easy to operate.

Double Block and Bleed

Trunnion mounted top entry ball valve is available in double block and bleed design.It ensures minimum fluid loss when the valve is open by providing double block and bleed features. The ball and seat design also makes this valve very reliable in high-pressure applications, which are sometimes prone to leakage due to ball freeze or corrosion.

Single piston effect (SPE)

Single Piston Effect (SPE) is a type of valve that operate on the principle of the force applied to a fluid by the piston. This type of valve also has a large bore in comparison to other types, making it best suited for high flow rates.

Double piston effect seat

Double piston effect is created by a seal that has two sealing points. This design creates a hermetic seal that is leak-free for the life of the valve

Side Entry Ball Valve VS Top Entry Ball Valve

Side entry ball valves are generally installed on the side of a tank or vessel. This type of valve is often used in industries such as petrochemical, chemical, food and beverage, power generation and marine. Side entry ball valves are also used for isolation purposes.

Side entry ball valves are different from the more common top entry ball valves in that they need to be oriented horizontally for operation. The valve assembly includes an internal spindle rod and packing gland which creates a seal between the valve body and the pipe to be closed off. The rod is threaded at one end which screws into a bushing at one end of the body tube to provide rotation for opening and closing the valve. The packing gland is located around this threaded end to prevent leaks by creating a seal with the pipe when tightening down on it.

Severe Service Compatibility

A severe service compatibility top entry ball valve is one that is designed to have a tight fit with the material it is passing through. This type of valve can be used for a variety of industries and applications, including those in the oil and gas and pharmaceutical industries.

The main difference between this type of valve and other valves on the market is its ability to maintain tight seal while in use. This means that the valve will not leak or release its contents during use, so it is ideal for high-pressure applications. A severe service compatibility top entry ball valve will generally cost more than other valves, but it is worth considering if you need a product that will keep your materials safe from leaks or spills.
