ASCO E290B053 Angle seat valve
It is a high-performance pneumatic angle seat valve designed for industrial fluid control and suitable for efficient on-off control of liquids, gases and steam. The valve adopts a 45° angle seat structure and has the characteristics of large flow, low flow resistance and fast response. It is widely used in food and beverage, pharmaceutical, chemical and HVAC industries.
