Products Description
In HVAC and water system, ball valves are used as automatic control valves.
It has adjustable flow ratio, high reliability and long ser vice life. It uses graphite to
strengthen the valve body sealing ring and double EPDM valve stem sealing ring.
It has integrated valve distribution butterfly inside and is not afraid of reverse pressure difference. It has the characteristic of equal percentage flow.
Its high turn-off pressure is 1.4MPa. The rated working pressure is PN20. The maximum working pressure difference is 0.35Mpa. It has a manual actuator short-circuit push button. Working temperature is -5 to 121 °C.
It is suitable for central air conditioning, hot and cold water supply system, steam humidification, etc.
