Product Overview

High pressure stainless steel ball valves are designed for high pressure applications where reliable performance and durability are critical. These valves are constructed of high quality stainless steel (316, 304, 316L) to ensure superior corrosion resistance, strength and service life under extreme conditions. The design typically utilizes a trunnion-mounted ball configuration to ensure that the ball is held securely in place under high pressure, preventing movement and ensuring a tight seal. The valve can be used as a switch for fluid flow, providing fast and reliable shutoff in high pressure systems. It is not intended for flow regulation, but to completely open or close the flow path as required.

Typically used in the oil and gas, chemical, power generation and water treatment industries, high pressure stainless steel ball valves provide a secure, leak-free seal in even the most demanding systems.

Product Features

HIGH PRESSURE HANDLING: These ball valves are designed to withstand high-pressure conditions and are typically rated up to 4,500 psi (or higher, depending on design). They are designed for severe service where pressure control is critical.

Trunnion Mounted Ball Valve Design: Unlike floating ball valves, which are more suitable for low pressure applications, the trunnion mounted ball valve design is standard for high pressure applications. The ball valve is securely fastened to prevent it from moving under pressure, ensuring that the valve is able to withstand extreme pressures without distortion.

OPEN/CLOSE FUNCTION: The high pressure stainless steel ball valve is primarily intended for use in open/close applications as a switch for fluid flow, not as a flow control valve. It is well suited for isolation or shut-off tasks in critical systems, but not for precise flow regulation.

Rugged material: These valves are made of high-grade stainless steel (316, 304, 316L) with excellent resistance to corrosion, abrasion and high temperatures, ensuring long service life and very low wear in harsh environments.

Leak-proof sealing: The trunnion mounting design ensures that the valves seal effectively at high pressures, with zero leakage in either the fully open or fully closed position. This makes them suitable for use in systems where leakage could lead to safety hazards or system failure.

Flanged or welded connections: These valves are usually equipped with flanged (ANSI, DIN) or welded connections to ensure solid integration into high-pressure piping systems. Threaded connections are not suitable for high-pressure ball valves, as they cannot withstand the corresponding stresses.

Product Advantages

Superior Pressure Handling: The trunnion-mounted ball valve design ensures that the valve can withstand extremely high pressures without compromising its integrity. The design is ideally suited for high pressure gas transmission, steam systems and petroleum pipeline applications.

Long service life: These valves are made of corrosion-resistant stainless steel to provide long service life even in the harshest environments. They require less frequent maintenance than valves made from less durable materials, resulting in long-term cost savings.

RELIABLE CLOSURE: These valves provide reliable and tight shutoff even under high pressure conditions. This is critical to preventing accidental fluid or gas leaks that could lead to hazardous situations.

Reduced risk of failure: The use of trunnion-mounted ball valves rather than floating ball valves significantly reduces the risk of deformation of the ball valve or damage to the valve seat under high pressure, thus increasing the reliability of the valve.

Enhanced corrosion resistance: Stainless steel construction ensures high resistance to corrosive media such as seawater, chemicals, acids and alkalis, which extends the service life of the valve even in corrosive environments.
