ADVERTORIALS Three-way ball sector valve with electric actuator


With the new type 4083, Schubert & Salzer presents a three- way ball sector valve with electric actuator for operation in diverting or mixing functions. The quarter turn valve with a supply voltage of 24–240 V DC/AC (50/60 Hz) enables high-precision control over a wide control range with Kvs values that are around 20% higher than those of common alternatives. Due to the special contour of the ball sector, the total volumetric flow remains virtually constant in any valve position.


Due to their unique properties, electrically or pneumatically actuated three-way ball sector valves offer particularly high added value in the temperature control and mixing processes of the steel, chemical, food and beverage industries as well as in power generation, the manufacture of plastic and rubber products and for use in test benches.

The SFC3000 is far more than just a dedicated flow computer. It can operate on a number of levels from a supervisory machine to a standalone flow computer or as a system component. With its touch screen VGA display and extensive processing capabilities, combined with simple to use controls and unique operating software, it can function as a complete station supervisor integrated into a flow computer housing. Designed specifically to meet the needs of the worldwide liquid hydrocarbon and gas measurement markets, the SFC3000 is intended to


positively contribute to both management and conservation of the world’s dwindling energy resources by providing both versatile and accurate measurement and incorporating state of the art designs and components. The SFC3000 flow computer should be considered the “brains” of a flow measurement system and requires a number of peripheral components to take measurements.

North Ridge Pumps supplied four heavy-duty horizontal multistage pumps to a client requiring the transfer of diesel at 30 bar pressure and a flow rate of around 60 m³/h. Since the client prefers to mount their own motor and baseplate, the pumps were provided in bareshaft form. They are being used at a thermal power plant to convert heavy fuel oil (HFO) into diesel.


Why might a power plant change from HFO to diesel? The switch may be made for several reasons, such as: • Environmental compliance: Switching from HFO to ultra- low sulphur diesel cuts sulphur dioxide emissions by 99%


and reduces particulates and CO2 by ~70%. • Fuel price and supply: HFO is cheaper, but diesel may be preferable if HFO prices rise or supply becomes unreliable.


• Operational flexibility: HFO requires heating and performs poorly at low loads, while diesel flows easily and ensures stable combustion. • Efficiency and maintenance: Diesel avoids engine problems linked to HFO at low loads, improving performance and reliability. • Availability: Diesel is often more practical for remote areas lacking consistent HFO supply.

Optimising Hydraulic Performance: Overcoming Challenges of Precision Flow Measurement


Titan Enterprises shares key insights to help engineers and operators navigate challenges of precision flow metering to ensure accurate measurements and safe process operations.


Metering liquids under pressure may seem straightforward at first glance - install a flowmeter in the product line, connect it to an instrument, control the measurement with on-board software, wire in a valve and pump, and switch the flow system on. However, real-world applications reveal a host of complexities that must be addressed to achieve precise and repeatable results.


Today’s advanced process and fluid handling systems demand highly precise flow measurement, and even slight incon- sistencies in system design can lead to inaccuracies, wasted product, or disrupted processes.


Where hydraulic systems are concerned, flowmeters play a critical role in maintaining the integrity and effectiveness of such systems used for instance, in hydraulic test rigs, calibration, confirmation of hydraulic pump outputs, plus setting and adjustment of flow control valves. Maintaining consistent process conditions, however, can be challenging. Hydraulic systems rely on the precise movement of fluid to transmit power, and any deviation from the required flow rate can lead to performance issues, excessive wear, or system failure. For instance, process conditions such as temperature fluctuations throughout the day can alter fluid viscosity and volumetric flow measurements, impacting flow measurement accuracy. Ideally hydraulic system designs should aim

to minimise as many variables as possible within a reasonable cost. Once this foundation is established, equipment such as flow meters, pumps, and valves can be selected to effectively compensate for any parameter variations.


Flowmeters are designed to measure the rate and/or volume of fluid flowing through a hydraulic system via a variety of outputs, from a simple mechanical display to full data logging, providing real-time data on the rate of fluid movement. This enables operators to monitor system health, detect leaks or blockages, and optimise performance. Accurate flow measurement is also crucial for maintaining consistent pressure and ensuring that actuators and other components receive the correct volume of fluid, which is vital for achieving the desired mechanical output.


Hydraulic fluids are typically viscous oils, petroleum or synthetic-based, utilised for their stability at operating temperature and lubricating properties, although water-based liquids (HFA, HFB), Water Glycol Fluids (HFC) and increasingly Biodegradable Hydraulic Fluids are also used within hydraulic systems. Titan Enterprises offer a range of flowmeters for hydraulic systems ranging from 10 to 950 bar, with bespoke flow variants and OEM versions also available.
