ASCO 298 398 - Pressure Operated Valves

ASCO Series 298 - 398 - 2 Way & 3 Way Pressure Operated Valves

Series 298 - 398 - Globe Valves

ASCO 298-398 range of robust 2 and 3 way pressure operated valves are ideal for use with steam, hot and cold liquids and inert gases.

ASCO 298-398 is designed to withstand most manufacturing processes even in harsh environments whilst being easy to maintain as the valve can be fully disassembled making cleaning quick and easy.

ASCO 298-398 is a cost effective solution as it has minimal heat loss when used with a hot media, the operator is designed to reduce air consumption, has a low piloting pressure meaning the valves are unaffected by dirty steam.

Mounting outdoors in any position is made possible by the valves water and dust protection system.

Series 298-398 is made of high quality robust materials enabling the product to withstand difficult and hot ambient atmospheres.  

Designed to resist the thermal shocks caused by exposure to steam and cold water, the life of the valves is greater than two million operations on saturated steam - for further flow control solutions please visit ASCO solenoid valves.
