NOSHOK Needle and Manifold Valves

NOSHOK's patented needle and manifold valves provide an innovative design, featuring a unique body-to-bonnet, metal-to-metal seal that significantly increases the pressure range of the valve without compromising the flow coefficient. The design also assists in maintaining the integrity of the bonnet threads by segregating them from the process media.

Built for maximum durability and performance in the toughest applications, NOSHOK valves are available with Zinc-Nickel plating, which provides one of the highest levels of corrosion resistance available. Additionally, all NOSHOK valves are 100% helium leak tested to 1 x 10-4 ml/s for guaranteed performance and reliability.

Valve models incorporating this patented design include the 100 Series hard seat mini valves, 800/850 Series bleed valves, all 2-valve block and bleed valves along with 5-valve manifolds.

The Teledyne ISCO Signature® Flowmeter

Teledyne ISCO Signature® Flowmeter
The Signature® flowmeter by Teledyne ISCO was created for open channel flow monitoring software.   The meter may compute flow using regular open channel level-to-flow and area velocity conversions, as well as user-defined equations, amount to area info points, or level to stream information points, depending on the application demand.

The Signature® flowmeter has unique features to verify data integrity.  It logs key events like changes in calibration and electricity outages to validate data accuracy.  Data are readily assessed to detect any kind of information alteration.  With multiple intelligent port options and multi-parameter logging (such as pH), the Signature flowmeter gives a common platform for control activity, reporting, and communicating.

Multiple flow technologies are available so that you are able to select the best flow technologies for the measurement site and channel requirements.  Accessible technology are: bubbler, ultrasonic, constant tide area velocity, and non-contacting LaserFlow™ velocity.
