Used across industries like petrochemical, water treatment, industrial gas processing, and chemical manufacturing, Superlok plug valves offer exceptional versatility. From high-pressure environments to compact installations with tight spatial constraints, these valves deliver precise fluid control and dependable performance.
Whether you need a space-saving, low-torque shutoff valve or a high-flow solution for rugged service, Superlok’s plug valves are designed to keep pressure systems efficient, safe, and easy to maintain.
Superlok plug valves are built to handle pressures of up to 3000 psig (206 bar) at a standard temperature of 100°F (37°C). This impressive pressure rating ensures that our valves can withstand the rigors of high-pressure environments without compromising performance.
These plug valves are designed to operate reliably in a broad temperature range, from as low as -10°F (-23°C) to as high as 400°F (204°C). This wide temperature tolerance makes them suitable for both cold and high-temperature applications.
Superlok plug valves feature a straightforward one-piece body design. Crafted from 316 stainless steel, these valves are not only durable but also resistant to corrosion, ensuring a long service life even in harsh operating conditions.
Every Superlok plug valve is built for dependable shutoff in demanding fluid and gas systems. With precision-machined internals and consistent sealing performance, they reduce the risk of leaks, pressure loss, and costly unplanned downtime.
Rated up to 3000 psig, Superlok plug valves are engineered to perform in high-pressure gas and liquid systems where strength and pressure integrity are non-negotiable. Ideal for isolation points in critical pressure systems.
Built to handle extreme service conditions from -10°F to 400°F, these valves provide reliable operation across a broad range of industrial and environmental applications—no matter the temperature swings.
Constructed from 316 stainless steel, Superlok plug valves deliver long-term durability even when exposed to aggressive media, harsh chemicals, or coastal humidity—making them a strong choice for corrosion-resistant fluid control.
The compact, one-piece body design minimizes leak paths and simplifies maintenance. Fewer parts mean easier installation, faster repairs, and greater system reliability—all without sacrificing performance.
From oil and gas and chemical processing to water treatment and petrochemical systems, Superlok plug valves are trusted across industries that demand precise fluid control with zero compromise.
Swagelok® plug valves have long been a staple in industrial fluid systems but Superlok plug valves have emerged as a reliable, cost-effective alternative that delivers the same performance, precision, and durability. In systems where fast shutoff, tight sealing, and corrosion resistance are critical, Superlok provides a smart solution without the premium price tag.
Superlok plug valves are precision-machined for high-pressure and high-temperature applications. Built from 316 stainless steel and other corrosion-resistant alloys, they’re engineered to withstand harsh conditions while maintaining smooth, low-torque operation. These valves are trusted across industries like oil and gas, chemical processing, water treatment, and petrochemical production, offering dependable sealing even after repeated cycling.
With leak-tight performance, wide compatibility, and rugged construction, Superlok plug valves are a strong drop-in alternative to Swagelok® models especially for teams looking to optimize system performance without compromising on quality. For procurement teams and engineers seeking alternatives, Superlok plug valves offer consistent performance, excellent availability, and simplified integration into existing pressure systems.
Whether you’re outfitting a new build or replacing aging infrastructure, Superlok delivers the durability and value today’s operations demand.

Superlok plug valves are designed to match the dimensions, pressure ratings, and port configurations of Swagelok® and Parker® equivalents making them fully cross-compatible with most instrumentation and process systems. You get the same form, fit, and function with consistent sealing and low operating torque.
Each valve is precision-machined to strict tolerances under ASME B16.34 and relevant pressure equipment codes. Threads are cut to ASME B1.20.1 standards to ensure reliable installation across system components, while internal flow paths are engineered for minimal pressure drop and smooth quarter-turn actuation.
Superlok plug valves are leak-tested and rated for high-pressure service up to 3000 psig and can be supplied with full interchangeability and pressure performance certifications.
Plug valves aren’t just another component—they’re a workhorse in any system that needs quick, reliable shutoff without babysitting. Superlok plug valves get used in the kind of industries where failure isn’t an option: oil and gas, chemical processing, refineries, water treatment plants, pharma production, and food-grade fluid systems.
What makes plug valves stand out is their ability to shut off flow instantly with a simple quarter-turn no hassle, no hunting for tools, no waiting on actuators. And when you’re dealing with high pressure, aggressive chemicals, or tight piping runs, that matters. Superlok builds theirs from 316 stainless steel, so they handle corrosive media, hot fluids, and repetitive cycling without wearing out or leaking over time.
You’ll see these valves used for anything from isolating lines during maintenance to purging equipment, controlling sampling lines, or handling backflow in pressurized systems. Their compact, low-torque design makes them perfect for space-constrained skids and control panels where you need dependable shutoff that fits. Point is they work wherever flow control is critical, and downtime is expensive.
Superlok plug valves are chosen by engineers who don’t have time for replacements, and ops teams who just need their systems to run clean and smooth. They’re spec’d when you need to trust that the valve you install today will still hold tight two years from now.
When you're dealing with tight project schedules, shutdown windows, or critical system maintenance, you don’t have time to “check back next week” for a valve that should be in-stock. That’s why SuperlokUSA keeps a fully stocked inventory of plug valves ready to ship no games, no guesswork.
We maintain a wide range of plug valve configurations in 316 stainless steel, from compact inline designs to high-flow models. NPT, socket weld, and panel-mount options are stocked and prepped for immediate fulfillment. Whether you're buying two valves for a sampling line or a full batch for a chemical process system retrofit, we’ve got what you need on the shelf, not on backorder.
Bottom line? When your system is down or your install is scheduled, Superlok gives you the peace of mind that your plug valves will be there when you need them not stuck in transit or tied up in distributor limbo.
