We often talk about the demands of the energy sector—the extreme temperatures, the corrosive media, and the sheer force of pressure required to keep things running. In these high-stakes environments, choosing the wrong valve isn't just a maintenance headache; it can be a catastrophic failure that halts production and compromises safety.

At Cornerstone Valve, our specialty is building the kind of robust, dependable valves that perform flawlessly when the pressure is on. We’re here to talk about the workhorses of critical industrial systems: the high pressure ball valve and the importance of investing in true severe service ball valves.

Pushing the Limits: The High Pressure Ball Valve

When your application operates above standard pressure classes—think thousands of PSI—you can’t rely on a general-purpose valve. You need a piece of equipment specifically engineered to maintain structural integrity and leak-free operation under constant, punishing force. This is the domain of the high pressure ball valve.

A typical ball valve is simple: a sphere with a bore in the middle rotates 90 degrees to start or stop the flow. But a high pressure model requires specialized design and metallurgy to prevent the pressure from deforming the ball or pushing it away from its seats.

Key Engineering Features for High Pressure

The difference lies in the details—details that Cornerstone Valve meticulously controls in our manufacturing process:

• Trunnion Mounting: Unlike floating ball valves where the ball is held in place solely by the pressure of the fluid, high-pressure valves rely on a trunnion (a shaft) at the top and bottom of the ball. This fixed support absorbs the immense pressure forces, reducing operating torque and ensuring a reliable, tight seal.

• Forged Body Construction: Forging produces a uniform, dense grain structure in the metal, eliminating the potential weaknesses and porosity found in some cast materials. This results in superior strength and resistance to pressure fatigue.

• Deep-Well Engineering: Our designs utilize advanced techniques, often exceeding standard API 6D or even API 6A requirements, to handle pressures up to 15,000 PSIG, common in deep well and hydraulic applications.

The goal of every high pressure ball valve we build at Cornerstone Valve is to provide superior shut-off performance with minimal maintenance, ensuring your fluid control is secure, no matter the force applied.

Beyond Pressure: True Severe Service Ball Valves

While high pressure is a major challenge, true "severe service" means a valve must handle multiple extreme conditions simultaneously. Your fluids might be corrosive (like sour gas), abrasive (slurry or sand), extremely hot (thermal processes), or cryogenic (LNG). A standard valve would quickly wear out, leak, or fail entirely.

Severe service ball valves are designed to operate reliably in these demanding environments, minimizing downtime and replacement costs. This is where Cornerstone Valve truly excels.

What Defines Severe Service?

A severe service application typically involves one or more of these challenging factors:

Every severe service ball valve from Cornerstone Valve is custom-engineered to address the specific combination of pressure, temperature, media, and cycle frequency unique to your plant.
