Product Overview

Top-mounted ball valve is a kind of control valve with compact structure and stable performance, which is widely used in petroleum, chemical, electric power, metallurgy and municipal engineering industries. The valve is suitable for water, gas, oil and corrosive media, with good high temperature resistance, corrosion resistance and pressure resistance. The top-mounted ball valve adopts a unique top-mounted design, the valve body and the actuator can be conveniently separated to facilitate on-site maintenance and overhaul, reduce downtime and ensure long-term stable operation of the system. Its ball body is quickly opened and closed by the actuator, with full flow, high flow rate and low flow resistance characteristics. Product advantages include good sealing performance, simple operation, long service life, easy maintenance, suitable for high-frequency opening and closing conditions. Top-mounted ball valves are widely used in cutting off, regulating and controlling fluids, which can effectively improve the safety and efficiency of pipeline systems. The valve is especially suitable for applications requiring high reliability and low leakage, and is an ideal valve choice for industrial automation systems.

Product Features

TOP-MOUNTED DESIGN: The top-mounted design is a highlight of this ball valve. With this design, the internal components of the valve, including the ball, stem and seat, can be accessed from the top of the valve body. This design makes maintenance and repair easier because there is no need to remove the valve from the pipeline, which significantly reduces downtime and labor costs.

Meets API 6D: This valve meets the rigorous standards of API 6D, the International Pipe Valve Code. It is designed to provide reliable performance in piping systems, ensuring a secure, leak-proof seal even under severe conditions.

Full bore and trunnion mounted ball valves: The full bore design ensures unobstructed flow paths for maximum flow and minimum pressure drop. Trunnion-mounted ball valves provide excellent support and precise flow control, even at high pressures, resulting in increased valve reliability and service life.

DURABLE CONSTRUCTION: The valves are typically made of high quality materials such as carbon, stainless, or alloy steel to provide superior corrosion resistance, mechanical strength, and toughness in extreme environments. Top-mounted ball valves can withstand severe operating conditions, including high temperatures and pressures.

Leak-proof design: The valve's design incorporates a variety of sealing characteristics, including metal-to-metal seals and soft seats (PTFE, PEEK), to ensure a reliable seal even under high pressure conditions.

MODULAR CONSTRUCTION: The modular construction of API top-mounted ball valves means that individual parts such as seats, balls and stems can be easily replaced without replacing the entire valve. This modular design provides significant cost savings and extends valve life.

Actuation Options: The valve is available with a variety of actuation options, including manual, electric, and pneumatic actuators. Electric actuators provide precise control, while pneumatic actuators offer fast and reliable operation for automated systems.

Advantages of the top entrance design:

Easier maintenance and repair: The main advantage of the top-mounted design is ease of maintenance. Because the valve body is fixed, internal components can be replaced or repaired without removing the entire valve from the pipeline. This reduces downtime, lowers maintenance costs and increases system uptime.

Reduced Installation and Disassembly Costs: The top-mounted design eliminates the need to remove the valve from the pipeline for servicing, thus eliminating costly and time-consuming installation and disassembly procedures. This reduces overall maintenance costs and improves operational efficiency.

Enhanced Safety and Operational Efficiency: Top-mounted ball valves minimize the need for system shutdowns or piping disassembly, which improves safety and maintains continuous operation. The design also facilitates inspection and maintenance in hazardous environments, reducing exposure to hazardous chemicals or high-pressure fluids.

Extended Valve Life: Trunnion-mounted ball valves and full bore design ensure that wear and tear on the valve is minimized, thus extending its service life. The top-entry valve design speeds up servicing and ensures that the valve operates for long periods of time without significant degradation in performance.

HIGH PRESSURE AND HIGH TEMPERATURE RESISTANCE: The top-mounted ball valve is ideal for high pressure and high temperature applications in the oil and gas, chemical and power generation industries. The valve can withstand extreme operating conditions and maintain reliable sealing performance under harsh conditions.

Reduced risk of leakage: The API 6D standard ensures that the valve meets stringent sealing requirements. The top entry design and its advanced sealing mechanism further minimize the risk of leakage and ensure safe and reliable operation.
