Asco-P-330A

ASCO™ 330A Volume Booster Valves

Product Description

The ASCO Series 330A Volume Boosters are flexible, robust, and highly reliable boosters designed to improve the pneumatic performance of both on/off and control valves. Available in sizes from 1/2 to 2 inches, the booster range offers a great deal of flexibility. Stainless steel and aluminum versions are available covering an operating temperature range of -60° C to +90° C. Solenoid valves can be close coupled to the booster via a NAMUR pad mount, making solenoid valve selection easier as well as improving performance. A unique mounting option enables the booster and actuator to be removed without disturbing the instrument piping.

The Series 330A Volume Boosters are just one product in a broad portfolio of valve actuator control components. These range from filter regulators and solenoid valves to cabinets that enable the operation and partial stroke testing of emergency shut-down valves, forming part of a safety instrumented system.
