Product 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.
