Schroeder Valves – Automatic Recirculation Valve (ARV) The Schroeder Automatic Recirculation Valve (ARV) protects centrifugal pumps from low-flow damage, dry running, overheating, and cavitation. It operates fully mechanically and requires no electrical power, sensors, or external controls. Core Function Installed on the pump discharge, the ARV ensures the required minimum flow at all times. When system demand drops below the safe operating range, the valve automatically opens a bypass and recirculates excess flow back to a tank or suction line. When normal flow returns, the bypass closes. This prevents: Excess internal heat Cavitation and erosion Seal and bearing damage Premature pump failure The pump remains within its defined operating limits without external intervention. Key Characteristics Self-acting hydraulic operation Integrated check and recirculation function Fast, stable response to flow changes Compact, robust construction Suitable for high-pressure and high-temperature service Material options such as carbon steel or stainless steel allow adaptation to various process media. Typical Applications The ARV is used where pump protection is critical and flow conditions fluctuate, including: Power generation and district heating systems Chemical and petrochemical plants Water treatment facilities Industrial processes with variable demand In these environments, maintaining minimum flow is essential for operational reliability and equipment longevity. As part of the portfolio of Schroeder Valves, the Automatic Recirculation Valve provides a reliable, maintenance-friendly solution for continuous centrifugal pump protection.

The harmful gases and odors caused by the activities of industrial facilities and enterprises pose a great threat to human and environmental health. It is necessary to develop some systems to protect our environment from these harmful substances. Gas purification systems installed in this direction contribute significantly to ensuring environmental safety. ERGIL Chemical Gas Washing Systems prevents the formation of acid rain by purifying the acidic gases from the exhaust before being released into the sky.

The Scully Connect Plus Sensor is an advanced tool-less overfill prevention sensor that allows for quick, easy and error-free installation of your overfill prevention system. It will save hours of installation time, prevent mis-wiring of the system, and allow for trouble-free connections. The patent pending sensor and cabling system has been designed for reliable operation and maximum safety. The sensor features a connector for simple sensor installation and replacement, and the new sensor levers allow for tool-less sensor access in tight spaces. The exterior cable connectors on the cap feature marine-grade watertight fittings. The sensor and cap have been extensively tested to withstand extreme environmental conditions.

The Scully Rack Tester is an advanced, comprehensive, portable tester approved for testing in hazardous locations. It allows Scully customers and field personnel to quickly assess any Scully overfill prevention, earthing and vehicle identification rack controller for proper equipment operation. In the event of a malfunction, it facilitates problem isolation and resolution.

Low-Profile Secondary Seal The Seal King low-profile secondary seal was specifically designed to give storage tank owners the ability to maximize tank working capacity. With its extremely low profile, the Seal King increases the working capacity of a floating roof tank, allowing tank owners to increase competitiveness and profitability. The Seal King also has unsurpassed vapor-sealing ability and exceptional water-shedding capability.

The Sealmaster floating roof seal system was developed over 35 years ago, with the goal of making a seal that adjusts to the irregularities of tanks while remaining gas-tight and virtually maintenance-free. The solution is the Sealmaster seal system. The Sealmaster is comprised of fully hardened compression plates, extending from the floating roof rim to the tank shell and down into the stored product, thereby providing a non-combustible protective sheath over a fully-heat-welded vapor barrier encapsulating the entire vapor space.

Thank you for attending StocExpo 2024! We look forward to seeing you on 11 & 12 March 2025!

SILEA series 513 semi-automatic coupler is used in the petrochemical industry when a dry coupling is required. It is mainly used to connect a bottom loading arm or a hose to a tanker equipped with a bottom loading adapter manufactured according to API RP 1004 standard regulations. The SILEA 513 coupler grants the loading operation without spillage and totally safe conditions to the operator, It complies with the European ATEX 94/9/EC and the PED 97/23/EC Directives.

Our services division provides commissioning and installation support, routine maintenance and inspections (PMIs), emergency repairs, retrofits and equipment upgrades, troubleshooting services, and -- in some markets -- full emission-testing services. The team is backed by a deep bench of engineering experts in emission control equipment design and operations. AEREON also maintains comprehensive inventory of the spare parts required to keep equipment operating efficiently including, in select markets, vapor combustors or flares that are available on a rental basis.

BJLM-80H servo tank gauges with MF smart displacers can be used to set up a Smart Tank Gauging System with multiple functions integrated in one gauge, aiming at measuring the bulk liquid stocks stored in ambient pressure. It features with MF displacer in which the density sensor, temperature sensor and water interface probe are integrated together. It performs multiple measurements upon commands, including the measurements for the liquid level, temperature, density, water interface level, and the tank bottom, and conducts the calculations of the volume, VCF and mass, providing data for custody transfers either in volume or in mass.
