Home » Block and Bleed Valves
Swagelok® block and bleed valves are commonly used in fluid and gas systems to isolate pressure points, relieve line pressure, and support calibration or sampling. But when it comes to lead time, cost, and ease of integration, Superlok offers a direct alternative without compromising quality or compatibility.
Superlok block and bleed valves are built to deliver the same functionality and reliability as Swagelok® units, using 316 stainless steel and other corrosion-resistant alloys for long-term durability. Whether used in instrumentation panels, pressure systems, or gas skids, Superlok valves provide precise fluid control and clean isolation between active and depressurized sections. With availability in single, double, and multi-valve configurations, these valves are commonly installed in chemical processing, pharma, oil and gas, and hygienic fluid processors, where safety and uptime are top priorities. The compact, forged design reduces leak paths and simplifies installation making them ideal for tight system layouts or OEM builds.
For businesses seeking a Swagelok® alternative that’s compatible with sanitary stainless steel fittings, available without long wait times, and backed by responsive U.S. fulfillment, Superlok delivers.

Superlok block and bleed valves are engineered to meet similar dimensional specs, pressure ratings, and thread standards as equivalent Swagelok® and Parker® models making them fully interchangeable across most instrumentation and process isolation systems. Comparable form, fit, and function.
Each Superlok valve is built from 316 stainless steel with body threads and connections manufactured to ASME B1.20.1 and valve housing tolerances conforming to ASME B16.34. This ensures repeatable performance, proper seal engagement, and a consistent fit every time. Whether you’re sourcing single-valve bleed bodies or multi-port block and bleed assemblies, Superlok valves drop directly into your existing spec with zero need for redesign. As proof, we’ve attached the official SGS interchangeability and burst-test certification.
Block and bleed valves are essential components in industries where safety, isolation, and accuracy are mission-critical. You’ll find them integrated into systems across oil and gas, chemical processing, pharmaceutical manufacturing, food and beverage production, and semiconductor facilities, where process sections must be routinely isolated for maintenance, testing, or calibration.
Superlok block and bleed valves are engineered to meet the stringent demands of these industries. Built from corrosion-resistant alloys like 316 stainless steel, these valves ensure reliable shutoff and pressure venting, even in aggressive or high-temperature environments. Their compact forged designs reduce leak paths while maintaining durability, making them a preferred choice for pressure systems and high-purity applications alike. Whether used in clean in place instrumentation, hygienic fluid processors, or automated analyzer loops, Superlok’s valves provide precise fluid control without sacrificing install flexibility. Thanks to compatibility with sanitary stainless steel fittings, they’re easy to integrate into both legacy systems and new builds that demand clean, efficient operation.
From gas skids to process panels, Superlok block and bleed valves help operators reduce downtime, protect personnel, and maintain total control over isolation procedures in the world’s most demanding industries.
SuperlokUSA maintains a fully stocked U.S. inventory of high-performance block and bleed valves, available in single, double, and multi-valve configurations to meet the needs of engineers and operators across demanding industries. Whether you're working on a gas distribution manifold, test panel, or analyzer system, having the right valve on hand ready to ship is non-negotiable.
Our block and bleed valves are manufactured from 316 stainless steel and other corrosion-resistant alloys, ensuring long-term durability even in aggressive chemical or offshore environments. With compatibility across sanitary stainless steel fittings, Superlok tube ends, and NPT/ISO threads, our valves can be integrated into both new and existing systems without rework or adaptation.
Superlok’s real advantage? Availability. While Swagelok® inventory often varies by region or distributor, we centralize fulfillment and ship nationwide cutting your wait time and keeping your system online. When your pressure systems demand a proven shutoff solution, our inventory delivers.
SuperlokUSA backs up its inventory strength with coast-to-coast fast shipping because even the best components don’t help if they arrive too late. Most block and bleed valve orders ship the same or next business day, backed by live tracking and streamlined handling through our trusted carriers.

Zachary AdlerOctober 18, 2024Trustindex verifies that the original source of the review is Google. I work in an academic lab, and we have been buying Superlok products for our gas lines. Previously, we used cheap connections that always came loose and leaked gases. Since we have switched to Superlok, we have had no issues of gas leaks. Their products are high quality with good prices. Wren has been very helpful with our orders, always sending updates on the status of our orders. I would definitely recommend Superlok.

Rodney LacyJune 23, 2023Trustindex verifies that the original source of the review is Google. While installing some import German equipment we needed to adapt from Metric to standard. We called Swedglok; the manufacture of the German end of the problem. It took 30 minutes to figure out what I was needing and to find that it will take a week to get it. I called Superlok. Wren knew right away what I was talking about. She had the solution in stock. During the exchange I needed to call her a number of times to up the quantity or change freight to early AM delivery. Wren was easy to reach and I felt her smile from my end of the phone. Good companies are made Great by the staff they employee. If this was an interview, I would hire Wren.
