Superlok check valves are engineered for reliable, unidirectional flow control preventing reverse flow and protecting system integrity. With a range of cracking pressures, end connections, and body styles available, these valves are trusted in chemical processing, fluid handling, and hygienic applications where precision matters.
Manufactured from corrosion-resistant alloys and sanitary-grade stainless steel, Superlok check valves deliver bubble-tight sealing, excellent resistance to system pressure swings, and minimal maintenance requirements. They’re built for demanding use whether you’re working with clean in place instrumentation, gas lines, or hydraulic networks.
Need dependable performance under pressure? These check valves offer smooth, consistent shutoff and precise fluid control keeping your system efficient and leak-free.
Whether you’re looking for a standard inline valve or something adjustable, SuperlokUSA gives you the options you need fast shipping, high-quality machining, and rock-solid performance. Add control, cut downtime, and make sure your fluid system runs exactly how it should.
Superlok check valves are engineered for consistent performance under pressure, delivering precise fluid control with durable, corrosion-resistant alloys. Built to the highest standards, they perform reliably even in harsh or sensitive environments.
From oil and gas to clean in place instrumentation and hygienic valves for food-grade systems, Superlok’s check valves adapt to a wide range of use cases. Our lineup supports everything from basic shutoff to complex pressure regulation.
Each Superlok check valve is designed to ensure true one-way flow, protecting critical systems by preventing backflow and preserving pressure integrity.
Used in pressure systems across chemical, pharmaceutical, and industrial plants, the SHCV series is trusted for its robust sealing and safety features—even in high-temperature or corrosive applications.
Superlok’s compact, one-piece and adjustable check valve options simplify installation and reduce system maintenance. These valves integrate easily into tight layouts without sacrificing performance.
Need something tailored? Superlok provides custom configurations to match your flow rate, cracking pressure, or material requirements—helping engineers hit spec without compromise.
When fluid control matters, Superlok check valves offer a dependable, cost-effective alternative to Swagelok®. Built for precision, durability, and pressure stability, these valves are engineered to perform in high-stakes environments from chemical processing and oil & gas to clean energy and instrumentation. Whether you’re managing backflow in sensitive pressure systems or integrating new components into existing pipelines, Superlok delivers the performance you need without the Swagelok® price tag.
These valves are a direct alternative to Swagelok® check valves, with full interchangeability in form, fit, and function. That means no need to rework your setup just drop them in and go. Superlok valves are trusted for critical flow direction control, especially in systems that require precise fluid control and uninterrupted operation. Manufactured with corrosion-resistant alloys and machined to tight tolerances, Superlok check valves ensure smooth, leak-tight operation under varying pressures and temperatures.
For operations requiring clean in place instrumentation, or hygienic fluid control in food, pharma, and semiconductor environments, Superlok’s compact valve designs minimize system complexity while maximizing reliability. Add in competitive lead times, U.S. inventory, and responsive support, and it’s clear: if you’re using Swagelok®, it’s time to take a serious look at Superlok.
