Hy-Lok Valves

PG Flowteknik Scandinavia is an authorized Hy-Lok distributor
PG Flowteknik Scandinavia has been an authorized Hy-Lok distributor since 2006 and has built a strong customer base in Denmark and Sweden over the years. What these customers have in common is a strong focus on quality, fast delivery, and reliable service.

Hy-Lok is known for supplying tubing connection and flow control components to industries such as oil & gas, petrochemical, power generation, shipbuilding, and semiconductor manufacturing. In recent years, their components have also proven highly suitable for the green energy sector.
Hy-Lok is recognized globally as a competitive alternative to established brands within instrumentation and process industries, offering cost-effective and fully compatible solutions for industrial piping systems.

History and Development
Hy-Lok was founded in 1977 with a focus on the design and production of double ferrule compression fittings and is today represented in more than 70 countries.

Hy-Lok Technology and Applications
The product portfolio includes double ferrule fittings, valves, manifolds, filters, and quick connect couplings. Across the entire range, products are available in multiple thread types and can be supplied with the double ferrule system.
They are designed for high-pressure and high-integrity applications and manufactured in materials such as stainless steel, brass, and advanced alloys including Monel, Hastelloy C276, and Super Duplex.

Hy-Lok emphasizes precision machining and quality assurance to meet the requirements of industries with high safety standards. Their components are widely used in process instrumentation, laboratories, marine applications, and energy systems where reliable sealing and corrosion resistance are critical.

Since 1977, Hy-Lok has developed into an international brand with certifications such as ISO 9001, as well as ASME and PED approvals.

 

Hy-Lok Ball valves

BALL VALVES

Hy-Lok ball valves are designed for safe and reliable shut-off in instrumentation and process systems.
They combine compact design with high pressure and temperature resistance, ensuring long service life, low leakage risk, and stable operation – even in demanding industrial applications.
A key advantage of many Hy-Lok valves is the integrated ferrule connection, providing a secure, leak-tight installation without additional fittings. This reduces installation time, minimizes errors, and increases overall system reliability in compact and process-critical installations.

Hy-Lok needle valves

NEEDLE VALVES

Hy-Lok needle valves are designed for precise flow control and safe shut-off in instrumentation and process systems where accuracy is critical.
They are engineered for high pressures and demanding operating conditions, delivering stable and repeatable control with excellent sealing performance and long service life.
In addition to threaded connections, Hy-Lok needle valves are available with integrated ferrule connections, ensuring direct, leak-tight installation without the need for additional fittings.

Hy-Lok relief valves

RELIEF VALVES

Hy-Lok Relief Valves provide reliable protection against overpressure.
They ensure controlled pressure relief and stable operation in applications with high requirements for safety, repeatability, and documentation.
Designed for demanding conditions and long service life with high integrity and operational reliability. Available with integrated ferrule connections for compact, leak-tight installation without additional fittings, reducing installation time and minimizing errors.

Hy-Lok Check Valves

CHECK VALVES

Hy-Lok check valves are designed to effectively protect instrumentation and process systems against backflow.
They ensure stable, one-directional flow in applications with high demands for operational reliability, process control, and repeatable performance.
The design is optimized for demanding conditions, offering long service life, high integrity, and reliable operation.
Integrated ferrule connections enable compact, leak-tight installation without additional fittings.

Hy-Lok ultra high purity valves

ULTRA HIGH PURITY VALVES

Hy-Lok Ultra High Purity (UHP) valves are designed for applications where cleanliness, material quality, and process control are critical.
They ensure contamination-free shut-off in installations with strict requirements for repeatability, documentation, and surface finish.
UHP valves are available with integrated VCR / ZCR face seal fittings, weld ends, or ferrule fittings to ensure the cleanest possible, leak-tight installation.

Hy-Lok manifolds er udviklet til kompakt og overskuelig samling af ventiler og instrumentering i proces- og målesystemer.

MANIFOLDS

Hy-Lok manifolds are designed for compact and efficient integration of valves and instrumentation in process and measurement systems.
They provide safe isolation, venting, and pressure equalization in applications with high requirements for reliability, repeatability, and documentation.
The design is optimized for demanding operating conditions and long service life, offering high integrity and robust construction.
Many Hy-Lok manifolds are available with integrated ferrule connections, enabling compact, leak-tight installation without additional fittings—reducing installation time and improving overall system reliability.
