The chemical industry has strict safety and environmental requirements. Standards such as ISO 15848-2 are in place to ensure that all processes are safe. Even a small leak to the atmosphere can turn into a serious issue. Consequently, monitoring and controlling fugitive emissions has become a high-profile concern for plant operators. The requirements for valves, stems, and valve body gaskets are also very stringent.
DT4 Tank Outlet Double Seat Mix Proof Valves
The DT4 Tank Outlet Mix Proof Valves provide a high level of separation between a tank and servicing pipeline. Part of the D4 Series mix proof family, these valves help companies meet customer demands for increased product quality, productivity, and flexibility in production. They are available in a variety of sizes, ranging from DN 40 to 100.
These valves feature dual independent plugs to allow for safe filling of a tank and minimise the risk of product contamination. Their unique top-loaded design and double lip seals help them meet stringent hygienic requirements. They also feature an optional SpiralClean cleaning system.
The DT4 Tank Outlet Double Seat Mix Proof Valve is an economical alternative to more sophisticated models. Its design allows it to be installed on a tank outlet or manifold, and its dual seat design allows it to handle different pressures simultaneously. It is available in shut-off, change-over, or tank bottom configurations. It can also be equipped with a leakage chamber for increased safety.
DT4 Throttle (Needle) Valve
DT4 Throttle (Needled) Valve is a highly versatile valve used in the flow control of high purity or corrosive fluids. Available in a variety of materials, these valves feature 24 pitch metering threads and excellent linearity of flow. In addition, the valve's bubble tight shutoff feature allows for precise flow control.
It works by increasing the surface area of fuel. The pressure in an airplane carburetor throat is 12.9 psi. As the plane climbs, this pressure increases to 14.2 psi. When an airplane is in this state of operation, the fuel is fed through a low-speed needle valve. When the airplane reaches higher speeds, the fuel is fed through the high-speed needle valve.
DT4 Chemical Injection Control Valve
The DT4 Chemical Injection Control Valve is a high-pressure, ultrasonic flowmeter with a valve and controller that can be remotely operated. Designed for high-pressure chemical injections, it has an IP66 rating and is ATEX/IECEx certified. The metering valve is also tolerant to particulates and has potential applications in the biotechnology, nuclear, pharmaceutical, and chemical industries.
