HOKE Inc. was founded in 1925 in the United States of America. In 1998, HOKE Inc. was acquired by the CIRCOR group, which is now one of the largest manufacturers of instrumentation valves and fittings, grab sampling systems and fluid control equipment in the world. HOKE valves offer a wide range of capabilities for various applications.

The DYNA-PAK design of our needle and ball valves provides superior sealing performance while reducing maintenance costs. Due to the alternate wafers of TFE and metal spacers design, stem leakage is eliminated. It also provides reduced operating torque, helps eliminate fugitive emissions and reduces the need for frequent packing adjustments.


In the early 60’s, HOKE Inc. took the industry by storm with the introduction of the GYROLOK Tube Fitting. All GYROLOK fittings are machined with total precision, ensuring a long-life and maximum performance.

Till this day, no other manufacturer has been able to improve on its unique design.

We strongly believe that no matter how good the manufacturing and design of our valves and fittings, only proper installation and handling can bring out its true value.

We strive to provide integrated custom solutions and end-user training programs to ensure that your installers and technicians thoroughly understand the product function and can effect proper installation and maintenance. We understand that safety is never optional, and are committed to improving and perfecting HSE practices through our workshops and additional support material.


Our range of HOKE tubings are available in various sizes and alloys, and can be ordered in metric and fractional measurements.

We also offer instrumentation tubings that meet ASTM A213/A269 standards, They fit perfectly with HOKE fittings to achieve reliable and leak-free connections.


GO REGULATOR was first introduced to the US market in 1962. Since then, its unmatched quality and excellent performance has been well recognised by global users. GO REGULATOR has always been the No. 1 choice of end users, especially in the process analytical field.

The GO product line includes single and dual stage, back pressure, dome loaded, high purity, liquid and gas pressure regulators, heated and vaporising regulators, and filters for process analyzers.


CIRCLE SEAL CONTROLS (CSC) was established in the US in the 1940s. CSC is committed to providing the most superior check and pressure relief valves, which are widely used in aviation, aerospace, alternative fuel and special gases industries. Till today, CSC remains the best choice for safety and system reliability for the aerospace industry among others.


We also offer a range of Grab Sampling and Custom Closed Loop Sampling Systems, expertly designed to meet the need for continuous tests and analyses. Such sampling systems have a wide range of applications across numerous fields such as oil & gas, petrochemical, chemical, refinery, power, pharmaceutical and even pulp and paper operations.

SilcoTek is the world’s leading provider of high-performance inert coatings applied by chemical vapor deposition (CVD). We became a coatings company because we have a passion for helping people and businesses conquer their most difficult material challenges and to develop Game-Changing Coatings that move scientific and industrial technology forward. SilcoTek offers custom coating services at our dedicated CVD coating facility. We don’t sell coated products because we’re solely focused on helping our customers improve their products.


CIRCOR manufactures flow and motion control products for the world’s most severe-service and mission-critical applications—from valves to instrumentation, actuation to pumps, motors to regulators.

Texas Sampling Inc.

Texas sampling (TSI) manual continuous sample system fulfils a variety of sampling needs. Our lowest priced basic system, the manual continuous sample system is a closed-loop sampler that is ideal for minimal pressure and temperature applications.

All manual continuous sampling systems collect emission -free representative samples of process while ensuring operator safety, easy to install and simple to operate, the sample is dispensed into the sample bottle by merely turning a valve.

Process pressure forces the sample through our patented valve design into the bottle and with process needle purge (PNP system), zero dead volume is ensured throughout the sample valve assembly.


DEKORON UNITHERM is the largest manufacturer of pre-insulated and heat traced bundles in the US. They serve global users by providing custom-design heat traced/control systems. This helps end-users achieve process efficiency, tangible energy saving and reduce pollution emissions.


Kinglai Hygienic Materials Co., Ltd. founded in 2000, is a manufacturing-oriented enterprise mainly engaged in R&D, production and sales of Hygienic materials with high-purity stainless steel as a base metal.

Main products are key components for Hygienic fluid pipeline system and ultrahigh vacuum (UHV) system, including vacuum chamber, sanitary pump, valve, flange, Tubes & fittings, etc.

They are mainly applied in such fields which need processing pollution control as biopharmaceuticals, electronic cleaning, and food.

Colson X-Cel Ltd

The company was founded by Andrew Taylor to manufacture small to medium CNC machined parts, with its first base being Wadsley Bridge near Sheffield.

The business quickly expanded; excellent quality of product combined with a commitment to customer service and reliability led to growth and the expansion into specialist areas:
