API 6D Forged Steel Flanged Ball Valve:Manual,DN 15-250 1/2

Characteristics of manual flanged ball valve:
1.Advanced valve seat: valve seat designed with years of experience in manufacturing ball valves ensures valve seal, low friction coefficient, small operation torque, various seat materials, and a wide range of application.
2. Handle with errorless switch: Using flat head valve rod to connect to the handle will not misplace so as to ensure that the on-off state of the handle deixis is in line with the valve.
3.Locking device: to prevent the valve from being switched with misoperation, there is a locking hole in the position where the valve  fully open and close to ensure that the valve is in the right place.
4.Structure avoiding flying of Valve rod : Valve rod is a low-installed type to avoid flying out by pressure while after the fire disaster,it can form metal contact with the body to ensure the valve rod of sealing.
Suitable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.
Applicable temperature: -196 ℃ ~ 350 ℃
Drive modes: manual, pneumatic, electric, hydraulic,ect.

Nominal diameter: DN 15-250 1/2 "- 10"
