Triple Offset Design:

Offset 1: The valve spindle is positioned behind the seat spindle.

Offset 2: The center of the spindle is offset from the centerline of the pipeline and the valve.

Offset 3: The seat cone shaft is offset from the centerline of the valve shaft.

Main Features:

1.Triple eccentric design for sealing zero leakage.

2.Bi-directional flowing medium & metal-to-metal sealing.

3.Laminated disc seal: The elastic seal is curved and energetic, achieve tight closing in both directions. Self-aligning: expansion due to temperature fluctuations.

4.High quality sealing effect & longer service life.

5.Small installation dimension, small opening/closing torque, small fluid resistance.

6.Range of working temperature: -45℃~538℃, valve body/disc material such as CS/SS304/SS316/AS can be chosen according to working conditions.

7.Connecting type: Flange, BW, Threaded connection.

8.Application: Petroleum and petrochemical, metallurgy, chemical industry, electric power, gas, water conservancy, municipal administration, and construction industries, etc.
