Hy-Lok D Vertriebs GmbH products

Hy-Lok compression fittings are precision-engineered solutions favored in numerous industries including chemical and petrochemical, oil refineries, power generation, shipbuilding, and the manufacturing of paper and microelectronics. Each fitting comprises a body, front ferrule, rear ferrule, and a nut, utilizing a two-ferrule design to address variances in pipe diameter, wall thickness, and material hardness. This design ensures leak-proof connections. Hy-Lok Super Duplex UNS S32750 screw fittings stand out for their high mechanical strength and exceptional corrosion resistance, making them suitable for challenging environments like offshore oil and gas sectors and high-pressure instrumentation systems. These screw fittings are designed for easy installation with standard hand-tools, superior sealing, and resilience against vibration at elevated pressures, especially when paired with SAF 2507 pipes.

The M Series valve blocks manufactured by Hy-Lok are expertly designed for integration with pressure and differential pressure instruments, including pressure gauges and transducers. Engineered to withstand process pressures of up to 410 bar (6000 psi) and operating temperatures as high as 648°C (1200°F), these valve blocks offer versatile installation options, either direct or in-line. The compact configuration makes them suitable for confined spaces where various instrumentation functions like shut-off, blow-off, bleeding, or zero-point calibration are necessary. They are particularly effective in systems handling sour gas due to the availability of PTFE or Grafoil seal materials that accommodate high-temperature environments. In addition to valve blocks, Hy-Lok provides pressure gauge shut-off valves and related accessories, enhancing the functional deployment of instrumentation in complex industrial settings.

Because oft the finely manufactured stem tip and valve design the MT1 series metering valves allow exact metering.

Hy-Lok's BL Series Bellow Valves are engineered to provide superior leak-tightness in critical environments, predominantly serving the semiconductor, biotechnology, and pharmaceutical industries. These valves cater to the demand for maximum purity, given their design which minimizes contact with media and exhibits high chemical resistance. The series offers connection sizes ranging from ¼” to ½”, with options for manual, toggle lever, or pneumatic actuation. Each valve undergoes a thorough passivation process in a nitrogen atmosphere and is subject to final cleaning in an ultrasonic bath, ensuring optimal cleanliness and functionality. This meticulous design and manufacturing process underscore the valve's ability to deliver precise shut-off without contaminating the medium, making them an ideal choice for applications necessitating stringent purity and reliability standards.

With its different connections, the spring-loaded safety valve AV619 offers blow-off volumes from 2.6 to 90.7 m³/h with opening pressures from 5 to 500 mbar that can be individually set at the factory. Different gasket materials are available, depending on the gas type. Thanks to its compact dimensions, the safety valve offers easy installation.
