Valworx 524310 球阀
Air Actuated 3-Way L-port PVC Ball Valve 1-1/4" - Double Acting
Valworx
Series: 5243 , Valworx 524310 air actuated 3-way PVC ball valves are used to control the flow of water and other compatible liquid media (not suitable for compressed air or gas). The L-port flow pattern can be used as a diverter valve or a selector valve. Ideal where NSF approved construction is required for potable drinking water as well as other industrial applications. Double acting actuators use an air pilot signal to open (position 2) and air to close (position 1). Actuator has standard ISO/Namur interface for mounting optional direct mount solenoid valve and other accessories. These actuated ball valves can be mounted in any orientation. Both female NPT and IPS socket end connectors are included with each valve. Advantages of air actuated ball valves over other type valves may include: higher flow rates, higher pressures, higher temperatures, wider media compatibility, straight through flow path and reduced water hammer. Ball Valve Standard Features Industrial quality True Union design Full Port for unrestricted flow Union nut locking device prevents back-off Four ball seat design allows for full pressure at any port Energized PTFE ball seats for lower torque and extended life Micro-adjustment of the ball seats Leak free dual stem seal design Certified per NSF61 G and NSF372 for use with potable/drinking water Air Actuator Standard Features Actuators designed for minimum 1 million cycles Rugged quarter turn rack & pinion design Highly visible valve position indicator Dry or lubricated pilot air Factory lubricated for normal life Anodized aluminum body with polyester coated end covers ISO/Namur mounting for valve accessories Options (see Accessories) Direct mount solenoid valves Position confirmation limit switches with visual indicator
