ASCO S290A414 | Solenoid Valve | Size 1/2-inch
ASCO series S290 pressure operated valves with a clamp connection or butt weld connection. Because of the sloped seat and anti-waterhammer design (fluid entry behind the disc), it has a high flow rate. allows for 360-degree rotation of a large variety of piston-type operators (32-50-63-90-125mm) for optimal performance at various pilot pressures. This version is suggested for steam applications that cycle quickly. The valves meet article 3.3 of the Pressure Equipment Directive 97/23/EC.
