ASCO 330 Series volume booster 

ASCO 330 Series volume booster from Emerson can be used in control and on/off aplications, and where partial stroke testing is required

Unique features enable improved reliability and easier maintenance and commissioning.Emerson has introduced the ASCO 330 Series volume booster to enable faster process valve opening and closing speeds. The booster can be used in both on/off and control applications and where Partial Stroke Testing (PST) is required.  Ideally suited for use in the upstream and downstream oil and gas market, the valve is flexible, robust and highly reliable. Available in stainless steel and aluminium, the booster complements other actuator control products from Emerson. These include switch boxes, solenoid valves, filter regulators and positioners.

Initially launched in ½" and 1" sizes, the 3/3 volume booster has been designed to simplify installation and maintenance tasks. The NAMUR pad mount for the solenoid valve makes the assembly compact and increases response speed. A unique connection option enables the valve to be removed from line without disturbing the pipework, simplifying maintenance and improving mean time to repair (MTTR). A modular inlet filter means that it is not necessary to have a high flow filter regulator upstream of the valve.  A compact filter regulator upstream of the solenoid valve is normally sufficient.

The combination of material options, certification and the fact that the booster can be used for on/off or control simplifies engineering, selection and spares holdings. The ASCO booster is SIL3 capable and has a wide range of certification, including ATEX and CUTR. Furthermore, the valve has been designed for use in temperatures from -60°C to +90°C, ensuring compatibility with environments ranging from the Arctic to the desert.
