Valtec’s high-pressure ball valves are engineered to withstand pressures up to 6,000 WOG (PN 414) and 10,000 WOG (PN 700). Their two-piece and three-piece investment-cast bodies, low-torque operation, and rigorous EN 12266-1 testing deliver leak-free performance in oil & gas, petrochemical, and industrial steam environments. Fully customizable for OEM branding, these valves ensure safety and reliability under the most severe process conditions.

Q1: What Defines a “High-Pressure” Ball Valve, and Why Is It Crucial for Severe Processes?

A high pressure ball valve is characterized by its ability to maintain a full-port seal under extreme pressure ratings (≥ 6,000 WOG or PN 414). Key factors include an investment-cast body rated to PN 414 or PN 700, blow-out-proof stem design, reinforced sealing seats, and anti-static devices. In severe processes—where pressures fluctuate rapidly or media are corrosive, hot, or hazardous—selecting a properly rated high-pressure valve ensures operational safety, prevents catastrophic leaks, and minimizes maintenance downtime. Proper specification also guarantees compliance with industry standards and helps protect personnel and equipment.

Q2: What Core Construction Features Define Valtec’s High-Pressure Ball Valves?

Q5: What Are the Primary High Pressure Applications for These Valves?

High-pressure ball valves are indispensable across several critical industries. In oil and gas pipelines, they act as emergency shut-off devices and deliver precise flow control under extreme pressures to safeguard both personnel and infrastructure. Within petrochemical plants, their fire-safe construction and corrosion-resistant materials allow them to handle aggressive or flammable media without compromising safety. Meanwhile, in industrial steam and hydraulic systems, these valves maintain a tight shut-off under high temperatures and fluctuating pressures, ensuring reliable operation and minimizing maintenance downtime.

Valtec’s high pressure ball valves combine robust construction, comprehensive safety features, and certified performance up to 10,000 WOG. With flexible customization for OEM branding and severe-service applications, they deliver the reliability your most critical processes demand.
