NDV offers ball valves compatible over a wide range of fields. Choose from our extensive line-up to meet your purpose from multi-way and v-port ball valves in addition to the standard fire safe type. We also take orders for special purpose valves used under high pressure, and those for shield machine and nuclear power plants.

NDV offers butterfly valves that excel in sealing and flow control properties. Our products have been received well as they include metal materials such as cast iron and stainless steel, and have superior corrosion resistance from PFA lining.

NDV provides the best valves for facilities with sanitary specifications, manufacturing medicine, food, and semiconductors. The bioclean diaphragm valve series are products that utilize diaphragm valve characteristics to its fullest potential with a "structure that does not contaminate fluids" and "structure with superior cleaning properties." Also choose from a selection of valves to meet requirements and the fluids from valves such as the sanitary type butterfly valve for medical containers.

Kurz offers a complete isokinetic sampling system to ensure true sample composition — from stack flow monitoring and sample capture to sample flow control. The Kurz Emissions and Sampling System provides accurate sample collection for environmental, process, and nuclear applications. It eliminates under- or over-reporting gas or particulate constituents. A wet stack option is available.

The Series 155 Mass Flow Computer is available in five models, depending on the number of flow meters and sensors in your flow meter system. The Series 155 Mass Flow Computer integrates the functions of temperature and flow measurement, closed loop flow control, flow totalization, alarms, input/output calibration, and data acquisition for up to 22 sensors.

The Kurz Series 255 Flow Averaging Transmitter is a versatile system transmitter designed for measuring flow rates in very large ducts that have non-uniform or unstable velocity profiles and/or wide temperature ranges. The Series 255 is a state-of-the-art microprocessor-based system that powers and reads up to 16 independent sensing points, providing a grand average of the flow and temperature. The Series 255 continuously reads and analyzes flow and temperature data from the individual channels, and automatically removes channels from the average that are under alarm or have been removed for service or repair. The Series 255 is designed for high reliability and high availability with multiple and independent power and communication ports so that wiring issues will not bring down the entire multisensor network.

The Model 2445 High-Temperature Portable Flow Meter is designed for very high temperatures (500°C) applications, such as coal-fired power plant stacks, and primary and secondary air ducts. The Model 2445 is available in five fixed lengths from 24” to 72” with a 3/4" diameter sensor support. The rugged all-welded construction and large size of the Model 2445 make it ideal for dirty and corrosive environments. It includes an all-metal display module, battery charger, carrying case, and several accessories.

The Model 2444 Heavy Industrial Portable Flow Meter provides the flexibility for a wide variety of field measurement applications because of multiple 16” sections that can connect up to 64.5” long. The Model 2444 works with high temperatures up to 200°C. It includes an all-metal display module, battery charger, carrying case, and several accessories.

The Model 2443 Flow Meter is a small, rugged sensor designed for velocity and temperature traverses in small- to medium-sized pipes/ducts, such as in industrial ventilation systems. The 13" long probe shield can be reversed to extend the 3/8” sensor support. It includes an all-metal display module, battery charger, carrying case, and several accessories.

The Model 2442 HVAC Portable Flow Meter is designed specifically for HVAC applications. The bendable gooseneck design and telescopic wand allows maximum flexibility in obtaining accurate traverse measurement in typically difficult location, such as ceilings, supply grates, and open areas. The wand reaches 47” when fully extended. It includes an all-metal display module, battery charger, carrying case, and several accessories

The Model 2441 Lab Grade Portable Flow Meter is excellent and well-suited for industrial hygiene and HVAC measurements. The dual-sting ceramic sensor is mounted in a ¼” diameter, 13” long sensor support with a shield/extender. The ceramic sensor provides a faster response time than the standard sensor. It includes an all-metal display module, battery charger, carrying case, and several accessories.

The Series 490-IS incorporates Kurz sensor expertise into an inexpensive miniature thermal air velocity meter that you can take anywhere. The 490-IS is ideal for velocity measurements for EPA and OSHA emission regulations for a wide variety of vapor emission sources.

The Series 504FTB in-line flow meter is designed for applications where flow disturbances or line size changes are not an issue. The 504FTB is available in 10 models for inline sizes from ½” to 4” pipes.

The Series 534FTB The Kurz 534FTB is designed with built-in inlet and outlet piping reducers/expanders to produce exceptional immunity to upstream and downstream flow disturbances caused by elbows, valves, and line size changes. The patented technology results in output with exceptional low end-to-end pressure drop and the fastest response to velocity and temperature changes in the industry.
