Bleed Valves

Bleed Valve By SuperlokUSA®

SuperlokUSA® bleed valves also known as drain valves—are designed for safe, controlled pressure relief in fluid and gas systems where trapped air, residual process media, or condensate needs to be vented without disrupting operations. These compact but robust valves are essential for ensuring safe shutdowns, efficient maintenance, and protecting critical components in pressurized environments.
Each bleed valve is machined from 316 stainless steel and built to perform in aggressive environments, offering excellent chemical resistance, corrosion protection, and long-term durability. The design includes a crimped safety cap to prevent unintentional disassembly during use and a precision-drilled vent hole that allows for slow, steady pressure release minimizing system shock or accidental discharge. These valves are frequently used in hydraulic, pneumatic, and instrumentation applications, particularly where pressure needs to be relieved during calibration, shutdown, or servicing.

Superlok bleed valves are available with multiple end connection styles including NPT, ISO threads, and direct compatibility with Superlok tube fittings making them easy to integrate into both legacy and new-build systems. Their compact form factor also makes them ideal for tight installs or high-density panel layouts.
If your system demands safe depressurization, reliable venting, and fast installation, Superlok bleed valves are the kind of component that keeps things clean, controlled, and running smooth.

Swagelok® bleed valves by Superlok

Swagelok® bleed valves are widely used in fluid and gas systems but Superlok offers a dependable, cost-effective alternative that doesn’t compromise on performance. Designed for controlled pressure relief, Superlok bleed valves match Swagelok® spec for spec while offering faster availability and better value for teams managing demanding systems.

Built from 316 stainless steel, Superlok bleed valves are engineered for leak-tight venting of gas or liquid from pressurized lines. The crimped cap prevents accidental disassembly, while the internal vent path provides steady, safe discharge ideal for high-pressure setups or sensitive applications like instrumentation, analyzer panels, and pneumatic control systems.

With precision threads and compatibility across NPT, ISO, and Superlok tube fittings, these valves are drop-in ready for both new installs and existing Swagelok® layouts. Whether you’re maintaining a chemical line, calibrating a gauge system, or bleeding residual pressure before service, Superlok valves offer reliable shutoff, corrosion resistance, and ease of use. For purchasing teams and system designers seeking a trusted alternative, SuperlokUSA provides high-quality bleed valves that meet the same functional standards as Swagelok® with the added benefit of fast fulfillment and a more competitive price point.
