Weld Neck Adaptor Flange, 230 PSI, 4" Valve

This Weld Neck Adaptor Flange is used with 4" M3P Control Valves that has a 230 PSI. The Z-one, a two-position spring return zone valve, is used in heating and air-conditioning systems. The Z-one series consist of a Z1 actuator which is easily attached to a Z2 (2-way) or Z3 (3-way) valve body. Z1 actuator is equipped with or without auxiliary switch. The Z-one actuator has a synchronous motor that winds the return spring and moves the valve paddle to the desired position. When power is removed the actuator spring returns the valve paddle. 24V actuators use a sealed reed switch for end switch, requiring no minimum current load.
