Home » Relief Valves
SuperlokUSA®’s pressure relief valves are critical safety components designed to protect pipelines, equipment, and systems from excessive pressure buildup. Each relief valve automatically releases pressure when it exceeds safe operating limits, preventing damage, leakage, or catastrophic failure. Engineered for precise fluid control and long-term durability, Superlok pressure relief valves are constructed from 316 stainless steel and corrosion-resistant alloys for superior strength and reliability in demanding environments.
With excellent sealing integrity and leak-free performance, these valves are built to handle high-pressure applications across industries like oil and gas, chemical processing, and hydraulic systems. Offered in multiple configurations, pressure ratings, and temperature tolerances, Superlok relief valves are adaptable to meet your specific system requirements.
These valves feature compact, precision-machined components that enable consistent, repeatable performance in high-pressure environments. Available with Viton (FKM), EPDM, or Kalrez sealing options, Superlok pressure relief valves maintain stability and resilience across a wide range of operating conditions. Depending on the seal material, temperature ratings range from -57°C to 260°C, making them a reliable choice even in extreme environments.
Superlok’s commitment to clean-in-place instrumentation and safety-driven design makes these relief valves ideal for hygienic fluid processors and pressure systems requiring uncompromising performance and efficiency.
In fluid and gas systems, pressure relief valves are essential for protecting pipelines, equipment, and personnel from dangerous overpressure events. For decades, Swagelok® has been a widely used brand in this space but Superlok relief valves have rapidly emerged as a trusted alternative. Designed for precise fluid control, system protection, and long-term reliability, Superlok’s relief valves offer a strong balance of quality, performance, and cost-efficiency.
Engineered from 316 stainless steel and corrosion-resistant alloys, Superlok pressure relief valves are precision-machined for leak-tight operation and consistent performance across a wide range of applications. Whether you’re working in oil and gas, chemical processing, pharmaceutical manufacturing, or hydraulic systems, Superlok valves are built to maintain safety and control in demanding pressure systems. Their clean-in-place compatibility and broad temperature tolerance make them ideal for hygienic fluid processors as well.
For teams looking to streamline system maintenance and enhance equipment protection, Superlok provides a compelling Swagelok® alternative. With multiple pressure ratings, temperature sealing options, and a modular design that supports easy installation, Superlok relief valves give engineers the flexibility they need without compromising on performance.
