Product Details

PTFE-lined ball valve is a professionally designed to control the opening and closing of various strong corrosive media. It is widely used in petroleum, chemical, dyeing, pesticide, acid and alkali production and other industries. It is the most ideal choice for anti-corrosion valves.

Key Features

1.The valve body is a precision casting valve body, qualified material, good appearance.
2.Using FEP lining, which has extremely high chemical stability.
3.Full-bore construction for leak-free shut-off over the entire pressure range.
4.Ball and stem are cast in one piece, which increases reliability and eliminates the possibilily of vaive stem punching out,ensuring safety
5.Using a special injection molding process, the seal is reliable and zero leakage.

Standard Test

Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

Seat Test: 1.1 times the working pressure with water.

Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close).

This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.

Special Test: On request, any other test can be carried out according to special instruction by client.
