product range for operations in diverting or mixing functions with the new type 4083. The quarter turn valve with a supply voltage of 24 – 240 V DC / AC( 50 / 60 Hz) enables high-precision control( rangeability of 100:1) 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 Kv value( volumetric flow) remains virtually constant in any valve position. OVC states its resilient seated butterfly valve has been designed to meet the demanding needs of today’ s water and industrial systems. This new valve is engineered for superior durability and reliability, offering a pressure rating of 250 – 300 PSI for dead-end service( up to 24” sizes). The vulcanised seat design ensures a secure, long-lasting seal and enhanced resistance to wear, chemicals and temperature variations, making it ideal for a wide range of applications. The heating of valves is particularly necessary for special applications such as when the media must remain fluid, according to Hartmann Valves. The company’ s new ball valve design integrates the heating jacket into the ball valve body and eliminates the need for welding double jackets. This effectively reduces the distance between the heating medium and the medium to be heated, which significantly improves heat transfer. Azbil Corporation has begun sales of its 6000 Series of control valves. Conforming to the IEC 60534 international standard, the 6000 Series represents a core product for the petroleum refining, petrochemical, chemical and related industrial markets. With an optimal design based on CFD analysis, the 6000 Series significantly enhances control performance while contributing to overall productivity improvements throughout a plant’ s lifecycle. GEMÜ has introduced the D41 diaphragm valve as part of its latest product generation, featuring EasyLock technology. This innovation allows maintenance in seconds, reduces complexity, and makes handling diaphragm valves significantly easier, reshaping the future of valve design. The pneumatically operated GEMÜ D41 is designed for aseptic manufacturing applications. Its sealing concept uses the newly developed GEMÜ diaphragm, which hermetically separates the actuator from the working medium. SAFI Valves presented an improved version of its best-selling butterfly valves, widely used in the chemical industry. The new range covers DN50 to DN150 and brings significant enhancements. These include:

built-in ISO 5211 plate for easier actuator installation; no visible metal parts for higher resistance in corrosive environments; gasket identifiable by disc colour( red for EPDM, green for FPM); lower operating torque for smoother operation; improved Kv for better flow performance; and available in PVC, PP, PVDF with EPDM or FPM sleeves. ORBINOX has re-engineered the PA pinch valves for diverse applications, such as mining, water treatment, flue gas desulphurisation, pulp & paper and the chemical industry. The new PA model pinch valve is a heavy-duty, enclosed construction full-bore valve with elastomer sleeves for flow shut-off and control in abrasive and corrosive slurries applications. The sleeve is the only part in contact with the media, no other mechanical parts are required and it is a maintenance-free part.
Forewarned is forearmed
Safety- always a top priority in any industry – is especially important where processes rely on, or produce, potentially hazardous chemicals. When incidents do occur, investigations conducted by bodies such as the CSB( The U. S. Chemical Safety and Hazard Investigation Board 5) can help to drive chemical safety, thereby protecting communities, workers and the environment.
Whilst valves are mentioned in some of the CSB’ s bulletins, the valves themselves are not necessarily the root cause of the incident. For example, in a 2023 Safety Alert, the CSB advises that while a discharge from emergency pressure-relief systems can help protect equipment from unexpected and undesired high-pressure events, it can also seriously harm or fatally injure workers and cause extensive damage to a facility if the discharge is not made to a safe location.
