Hunt Valve: Proportional Poppet Valve

Hunt Valve Proportional Poppet ValveHunt Valve has announced a new proportional poppet valve for descaling applications that lasts three to five times longer than traditional poppet valves. By eliminating the effects of water hammer and system shock, this innovative poppet valve technology promotes safety in the plant and cuts operating costs in half.

At steel mills, persistent water hammer in high-pressure piping systems often leads to burst pipes, cracked welds and descale header damage. Hunt Valve’s proportional poppet descale valve can be programmed to eliminate water hammer in the system. Typically, the speed is only reduced for the last 10 to 20% of the stroke, just before completely shutting off flow to the descale header. This slow rate of closure can be fine-turned via the integrated local control interface or programmable logic controller (PLC).

Spirax Sarco: VLM20 Inline Vortex Flowmeter

Spirax Sarco VLM20 Inline Vortex Mass FlowmeterSpirax Sarco announces the rebranding of the VLM10 Inline Vortex Flowmeter to VLM20. The VLM20 utilizes a common electronics platform that is now available in all the new 20 Series Meters to improve reliability and ease of use across the product line. The VLM20 utilizes a SMART multivariable transmitter with integral temperature and pressure sensor giving users an elegant all in one solution for their measurement needs. A precision 1000 Ohm RTD and absolute pressure sensor are used to calculate density for mass flow and thermal energy flow from chilled, hot water and condensate return system.

The VLM20 is precise and reliable with a steam or gas mass flow accuracy of ± 1.5% of rate over a wide 30:1 flow range. Digital communications deliver real-time calculations of density, temperature, pressure, mass and thermal energy flow using Modbus RTU, BACnet® MS/TP and HART® communications in addition to the standard analog, pulse and relay outputs.

The VLM20 is available in line sizes ½" to 12" with flange ratings up to 600lb. ANSI. Wafer connections are also available from ½" – 4". Wetted material includes carbon steel and 316L stainless steel.

ASCO: Zoned Safety Capabilities in Numatics 503 Series Valve Manifold

ASCO Manifold Zoned SafetyASCO has introduced the capability to integrate multiple safety zones within a single Numatics 503 Series valve manifold. This new zoned safety approach helps the design engineer satisfy the Machinery Directive 2006/42/EC and comply with ISO 13849-1 while eliminating the components and complexity found in discrete safety circuits.

The zoned safety concept is an integrated approach to machine safety and control that greatly simplifies the design of a redundant pneumatic safety circuit with a manifold system. The Numatics 503 Series can create up to three independent electro-pneumatic safety zones, while also allowing independent non-safe sections to co-exist within one manifold assembly. The operator does not have to shut down the entire machine by releasing compressed air with a redundant safety/control dump valve. Instead, the Numatics 503 Series valve manifold can be configured to shut down air and power only to the group of valves that controls the machine’s motion in the operator’s vicinity.

Val-Matic: Air Valve Sizing Software

Val Matic AirValveSoftwareScreenShotVal-Matic’s AirValve Sizing Program is a web-based software program designed to aid in selecting Air Valves along a pipeline. Users are able to enter and save design information specific to their pump, water pipeline or wastewater forcemain to calculate the locations and sizes of AWWA Air Valves. The program will also calculate the collapse pressure, slope and gravity flow in the pipe. Recommendations are given for Air Valve locations, sizes and model numbers for pipeline and pump discharge locations. To use the software, visit www.valmatic.com.
