Cast steel electric ball valve
1)material: WCB, cast steel
2)DN: 10~300
3)connection: Internal thread
4)PN: 1.6, 2.5, 4.0, 6.4Mpa
5)working temperature:
PTFE: ≤ 180° C
PPL: ≤ 300° C
Metel seal: ≤ 425° C
6)medium: Water, oil, steam, acid, alkal
Features:
1) Electric ball valve fluid resistance is small, has the minimum fluid resistance in all valves, with AC220V, AC380V or DC24V power supply voltage, Accept (4-20 ma, 0 to 10 ma, or 1 to 5 VDC) current or voltage signal, and can control operation, to Angle the itinerary of the output torque rotating sphere in 0 ~ 90 ° , opening and closing action or adjust the action will be finished
2) Ball core channel level off is smooth, not easy sedimentary medium, can be in-line ball. Simple structure, light weight, good sealing performance. Especially suitable for the requirement of zero leakage rate
3) The structure of the electromechanical integration design, machine servo operation and opening position feedback signal, position indicator, manual operation, and other functions, functional, reliable performance, simple connections

We are valve manufacturer specialized in the industrial valves utilized in the server application environment against high temperature, high pressure, high corrosive and low temperature or cryogenic application ranging from petrochemical, offshore, chemical, gas, power plant, shipyard to long distance pipeline and pharmacy or other industries. Valve types vary from ball valve, globe valve, check valve, gate valve, butterfly valve to plug valve, and also from tank bottom valve, sampling valve, double block & bleed valve, strainer to sight glass.
Valve material are available from Titanium, Nickel alloy, Zirconium, Nickel-Aluminum-Bronze, (Super) Duplex to alloy 20#, 904L, 310S, 321, 347 or other anti-corrosive alloys. With emphasis on quality consistency and innovative design, we gradually turn to be reliable business partner for plenty engineering companies and end users all over the world.
