1 CONTROL VALVE STANDARD SPECIFICATION ON-OFF 2,3-WAY GLOBE VALVE YAD-112Q1/11231 Series YAC Series YAC Series [B-8]

Standards combined actuators are Cylinder & Diaphragm actuator is standard application.

2 GENERAL The single soft seat control valves are designed for compact and leakage zero (Metal seat : ANSI Class Ⅳ std. tight sut off : Ⅴ). The valve simple construction having low pressure loss, high accuracy flow characteristics. The flow shut-off performance complies with the JIS standards. Standards combined actuators are Cylinder & Diaphragm actuator is standard application. FEATURES Light and compact Easy to handle Ideal for packing of equipment Easy maintenance Construction is simple, and dismantling and checking are easy. High reliability and safety action Assurance for emergent safety action due to actuator of spring returns type or double acting type. Most suitable for simple instrumentation control at small and medium plants - Suitable for on-off control of 1K or less - 1 -
